The Largest Known Dinosaur
The Largest Known Dinosaur. Sketch reconstruction of Brachiosaurus, from specimens in the Field Museum in Chicago, and the Natural History Museum in Berlin.
Steel Bow to diminish curvature of the spine
Steel Bow to diminish curvature of the spine I have made a steel bow which receives the head longitudinally from the forehead to the occiput; having a fork furnished with a web to sustain the chin, and another to sustain the occiput. The summit of the bow is fixed by a swivel to the board going behind the head of the bed above the pillow. The bed is to be inclined from the head to the feet about twelve or sixteen inches. Hence the patient would be constantly sliding down during sleep, unless supported by this bow, with webbed forks, covered also with fur, placed beneath the chin, and beneath the occiput.

Skulls of Horned Dinosaurs
Skulls of Horned Dinosaurs. The lower row, Ceratops, Styracosaurus, Monoclonius, are from the Middle Cretacic (Belly River formation) of Alberta; Anchiceratops is from the Upper Cretacic (Edmonton formation) of Alberta; Triceratops and Torosaurus from the uppermost Cretacic (Lance formation) of Wyoming.

Skeleton of Tyrannosaurus in comparison with human skeleton
This animal probably reached the maximum of size and of development of teeth and claws of which its type of animal mechanism was capable. Its bulk precluded quickness and agility. It must have been designed to attack and prey upon the ponderous and slow moving Horned and Armored Dinosaurs with which its remains are found, and whose massive cuirass and weapons of defense are well matched with its teeth and claws. The momentum of its huge body involved a seemingly slow and lumbering action, an inertia of its movements, difficult to start and difficult to shift or to stop.

Chair to assist in straightening of the spine
Chair to assist in straightening of the spine Where frequent lying down on a sofa in the day-time, and swinging frequently for a short time by the hands or head, with loose dress, do not relieve a beginning distortion of the back; recourse may be had to a chair with stuffed moveable arms for the purpose of suspending the weight of the body by cushions under the arm-pits, like resting on crutches, or like the leading strings of infants. From the top of the back of the same chair a curved steel bar may also project to suspend the body occasionally, or in part by the head, like the swing above mentioned. The use of this chair is more efficacious in straightening the spine, than simply lying down horizontally; as it not only takes off the pressure of the head and shoulders from the spine, but at the same time the inferior parts of the body contribute to draw the spine straight by their weight.
Building a wharf
Building a wharf, about 1650. (Conjectural sketch by Sidney E. King.) Piers and Wharfs.—In order to accommodate such large sailing vessels, piers and wharfs had to be built at Jamestown. A 1,300-pound iron piledriver was found in the basement of a 17th-century building in 1955. It was probably used three centuries ago for driving piles in the James River during construction of a small wharf.
