- Normal position of the larvæ of Culex and Anopheles in the water
(a) Normal position of the larvæ of Culex and Anopheles in the water. Culex, left; Anopheles, middle; Culex pupa, right hand figure - "Earth" of the Fox
Mother fox bringing food to its young. The fox is a well-known burrower, its "earth" being familiar to many by by sight, and to all by name. Few persons, who do not know the history of the fox, would believe it to be capable of forming excavations of such extent. The fore feet of the mole are clearly formed for digging, their sharp claws penetrating the earth, their broad palms acting as shovels, and their powerful muscles giving the needful force. These limbs are essentially used for digging, and are but little employed as means of locomotion. But the fox is an admirable runner, as any hunter can avouch, and its fore limbs are formed for speed and endurance, their length enduing them with the one quality, and their muscular lightness with the other. Yet, just as the digging limbs of the mole are used fr locomotion, and enable the animal to proceed at no contemptible speed, so the running limbs of the fox are used for digging, and e nable the creature to excavate burrows of no contemptible dimensions. - 'Dinah'

) Eurasian dotterel ( Charadrius morinellus ) - 2) Plover ( Charadrius pluvialis ) - 1) Sea-pier ( Arenicola piscatorum ) .— 2) Parchmental Bristleworm ( Chaetopterus pergamentaceus ).
Tube dwellers without gills ( Abranchiata ) include the Bristleworms ( Chaetopterus), which differ markedly from all other members of the order and represent a separate family. With them, too, the body consists of three uneven divisions. The head of the species shown here is funnel-shaped, cut at the back and fitted with two probes here. The following 9 segments have elongated, flat foot stubs, which bear a bundle of brown brushes at the top edge. Very remarkable is the shape of the 5 segments of the middle section. The last 3 are missing the top foot stubs; those of the first two form a comb on the middle of the back with 2 feel-like protrusions, which extend far over the front part of the back. The lower stubs on the first segment are broad, curled towards the belly and joined here; on the other 4 segments they have a triangular shape and a sideways direction. The second segment is very swollen and purplish black in color. The posterior body part consists of about 50 members, which shine very wide due to the strongly laterally extended foot stubs. The animal in question was found in deep water on the coast of Normandy and in the Mediterranean Sea. It reaches 22 cm in length. and is surrounded by a 32 cM. long sleeve, made of a multi-layered material, resembling coarse, yellowish parchment. - 1, 2) Sand worms ( Hermella ): 1) Tubes of Hermella alveolata with its inhabitants (2). 3) Shell tube worm ( Terebella emmalina )
The third group of tube worms is formed by the gillheads ( Cephalobranchiata ), so called, because the softened thread or tree-shaped appendages for breathing are at the head or at least at the anterior segments. They inhabit tubes from which they never emerge voluntarily. Accordingly, the appendages of most segments, except the anterior ones, are much less developed than those of the free-living many-bristles, and the way of life is more peaceful, as evidenced by the absence of dental plates in the oral cavity. - 3 Giraffe

One great part of the joculator's profession was the teaching of bears, apes, horses, dogs, and other animals, to imitate the actions of men, to tumble, to dance, and to perform a variety of tricks, contrary to their nature; and sometimes he learned himself to counterfeit the gestures and articulations of the brutes. - A calf

A diagram showing the life-history and migration of the Malaria parasite, Laverania Malariæ, as discovered by Laveran, Ross, and Grassi. The stages above the dotted line take place in the blood of man. The oblong-pointed parasite is seen entering the blood at n just below No. 1. The circles represent the red blood-discs of man. Schizogony means multiplication by simple division or splitting, and it is seen in Nos. 6, 7, 8, 9, and 10. The stages below the dotted line are passed in the body of the spot-winged gnats of the genus Anopheles. A peculiar crescent or sausage-shaped condition is assumed by the parasite inside the red corpuscle No. VI. These are found to be of two kinds, male and female, Nos. VIIa and VIIb. They are swallowed by the spot-winged gnat when it sucks the blood of an infected man. Here in the gut of the gnat they become spherical; the male spheres produce spermatozoa No. Xa, which fuse with and fertilize the female spheres or egg-cells No. XI. An active worm-like form No. XIII results, which pushes its way partly through the wall of the gnat’s gut, and is then nourished by the gnat’s blood. It swells up, divides internally again and again, and is enclosed in a firm transparent case or cyst, Nos. XIV to XVIII. The cysts are far larger in proportion than is shown in the diagram, and are visible to the naked eye. The final product of the breaking up, which is called sporogony, is a vast number of needle-shaped spores or young (called Exotospores, as opposed to the Enhæmospores, which are formed in the human blood, as seen in Nos. 9 and 10, and serve there to spread the infection among the red corpuscles). The needle-shaped spores formed in the gnat’s body accumulate in its salivary glands, and pass out by the mouth of the gnat when it stabs a new human victim who thus becomes infected, No. XIX. - A dissection scene
A dissection scene - A faithful companion
A gardener, in removing some rubbish, discovered two ground toads of an uncommon size, weighing no less than seven pounds. On finding them, he was surprised to see that one of them got upon the back of the other, and both proceeded to move slowly on the ground towards a place of retreat; upon further examination he found that the one on the back of the other had received a severe contusion from his spade, and was rendered unable to get away, without the assistance of its companion! - A Fish-louse (Caligus rapax), Female

- A Ganglion of a Leech
Pear-shaped cells are set round a felt-work of nerve-fibrils (neuropil). A neuro-sensory cell is shown with one fibre directed peripherally, branching on the surface; and one directed centrally, ramifying in the neuropil. Several very slender fibrils from the neuropil pass up the stalk of each ganglion-cell. They join a network near its surface. This net is connected by radiating fibrils with a coarser net which surrounds the nucleus. From the central net a relatively stout fibril passes to muscle-fibres. - A grateful return
A favourite house-dog, left to the care of its master’s servants, while he was himself away, would have been starved by them if it had not had recourse to the kitchen of a friend of its master’s, which in better days it had occasionally visited. On the return of the master it enjoyed plenty at home, and stood in no further need of the liberality it experienced; but still it did not forget that hospitable kitchen where it had found a resource in adversity. A few days after, the dog fell in with a duck, which, as he found in no private pond, he probably concluded to be no private property. He snatched up the duck in his teeth, carried it to the kitchen where he had been so hospitably fed, laid it at the cook’s feet, with many polite movements of the tail, and then scampered off with much seeming complacency at having given this testimony of his grateful sense of favours. - A Gray Parrot on His Perch. Waiting to Speak His Piece
Best known among them as a cage-bird is the Gray-parrot, the ablest talker of the family, the amusing Poll-parrot seen in so many homes. Though a cage is provided, they become such home-bodies as to be given all the liberty they want, being often free to go about the house, though they look upon the cage as their special dwelling place. - A Hooded Peregrine Falcon. Its eyes are covered by the hood until the game is in sight
It is called Hawking or Falconry, and is a very old sport in which the falcon or the hawk was used to take game. It is still in use in some countries, but in old times falconry was the favorite sport of kings and nobles, many of whom spent much of their time in the field, hunting smaller or weaker birds by aid of the strong and swift falcon or hawk. This kind of sport began very long ago, no one can say how long, it being common in Asia long before it was known in Europe. And it is common in some parts of Asia still. - A horse

In Milan the visitation of 1630 was credited to the so-called anointers,—men who were supposed to spread the plague by anointing the walls with magic ointment—and the most horrible tortures that human ingenuity could devise were imposed on scores of victims, regardless of `rank` or of public service. Manzoni's great historical novel, "The Betrothed" has well pictured conditions in Italy during this period. - A millipede
The Diplopoda, or millipedes, are characterized by the presence of two pairs of legs to a segment. The largest of our local myriapods belong to this group. They live in moist places, feeding primarily on decaying vegetable matter, though a few species occasionally attack growing plants. The millipedes are inoffensive and harmless. Julus terrestris, and related species, when irritated pour out over the entire body a yellowish secretion which escapes from cutaneous glands. It is volatile, with a pungent odor, and Phisalix (1900) has shown that it is an active poison when injected into the blood of experimental animals. This, however, does not entitle them to be considered as poisonous arthropods, in the sense of this chapter, any more than the toad can be considered poisonous to man because it secretes a venom from its cutaneous glands. - A Minute Portion of the Pulp of the Spleen

Horse carrying a dog in its mouth - A Pair of Angora Goats
The other wool-yielder is the Angora goat, well known in this country. This yields a thick and fine wool, soft and silky and slightly curled. The color is mostly snow-white, though at times there are dark patches. It is shed in great locks in summer, but soon grows again. During the hot weather the goats are constantly washed and combed, to add to the beauty of their wool. The finest Angora wool, called Mohair, comes from goats a year old. All its value is lost at six years of age. - A prairie dog town
The burrows are of considerable dimensions, and evidently run to no small depth, as one of them has been known to absorb five barrels of water without being filled. They are dug in a sloping direction, forming and angle of about forty-five degrees with the horizon, and after descending for five or six feet, they take a sudden turn and rise gradually upward. The prairie dog has not the privilege of possessing a home exclusively devoted to its own use, for the Burrowing Owl, and the terrible rattlesnake, take forcible possession of the burrows, and devour the inmates, thus procuring board and lodging at very easy rates. - A Rose hip

- A Sly Couple
A gentleman in the county of Stirling kept a greyhound and a pointer, and being fond of coursing, the pointer was accustomed to find the hares, and the greyhound to catch them. When the season was over, it was found that the dogs were in the habit of going out by themselves, and killing hares for their own amusement. To prevent this, a large iron ring was fastened to the pointer’s neck by a leather collar, and hung down so as to prevent the dog from running, or jumping over dykes, &c. The animals, however, continued to stroll out to the fields together; and one day the gentleman, suspecting that all was not right, resolved to watch them, and to his surprise, found that the moment when they thought that they were unobserved, the greyhound took up the iron ring in his mouth, and carrying it, they set off to the hills, and began to search for hares as usual. They were followed, and it was observed, that whenever the pointer scented the hare, the ring was dropped, and the greyhound stood ready to pounce upon poor puss the moment the other drove her from her form, but that he uniformly returned to assist his companion after he had caught his prey. - A solpugid (Eremobates cinerea)
The Solpugida have long borne a bad reputation and, regarding virulence, have been classed with the scorpions. Among the effects of their bites have been described painful swelling, gangrene, loss of speech, cramps, delirium, unconsciousness and even death. Opposed to the numerous loose accounts of poisoning, there are a number of careful records by physicians and zoölogists which indicate clearly that the effects are local and though they may be severe, they show not the slightest symptom of direct poisoning. - a strange and terrible fruit
