Lee Leaving Appomattox Court House So Lee fell back towards Lynchburg, but on April 9th, 1865, being entirely surrounded by Grant’s vast army, he and his few ragged men surrendered to General Grant at Appomattox Court-House. Lee had only eight thousand men, while Grant’s army numbered about two hundred thousand. - Lee Simonson

The men may be permitted to wield the rifle left handed, that is on the left side of the body, left hand at the small of the stock. Many men will be able to use this method to advantage. It is also of value in case the left band is wounded. - Left side of 5-cm mortar

- Lemming
The most famous species of this genus, the Lemming (Myodes lemmus, Lemmus norwegicus) reaches a total length of 15 cM., of which at most 2 will be on the tail stump. The richly stuffed, long-haired coat exhibits a very graceful sign. In the case of the brownish-yellow ground colour, which is fitted in the neck with wave lines, dark spots protrude; two yellow stripes stretch from the eyes to the rear. The tail and legs are yellow, the parts yellowish, almost sandy. - Lemon
Recipe from the 1653 book (with original spelling) Take Lemmons, rub them upon a Grate, to make their rinds smooth, cut them in halves, take out the meat of them, and boyle them in faire water a good while, changing the water once or twice in the boyling, to take away the bitternesse of them, when they are tender take them out and scrape away all the meat (if any be left) very cleane, then cut them as thin as you can (to make them hold) in a long string, or in reasonable short pieces, and lay them in your glasse, and boyling some of the best White-wine vineger with shugar, to a reasonable thin Syrupe, powre it upon them into your glasse, and keep them for your use. - Lenormand’s parachute, 1784
Previous to Lenormand’s experiments, Blanchard, the aëronaut, had dropped small parachutes from his balloon, sometimes carrying animals, but never a human being. For unaccountable reasons the world had to wait fourteen years longer to see a man make the new familiar parachute descent from a balloon. On October 22, 1797, in presence of a large crowd Jacques Garnerin ascended in a closed parachute to a height of 3,000 feet, then cut loose. The people were astonished and appalled; but they soon saw the umbrella-shaped canvas spread open and oscillate in the sky with its human freight. As it was but eight yards in diameter, it descended rapidly and struck the ground with violence, throwing Garnerin from his seat. He escaped with a bruised foot, mounted a horse, and returned to the starting point, where he received a lively ovation. - Leo

- Leon M Gambetta
Léon Gambetta, an eminent French statesman and founder of the French Republic. When he died from a pistol wound, in 1882 ,at 44 years of age, his brain was found to weigh 40.9 ounces, whereas boys of 7 to 14 years of age average a fraction less than 46 ounces. Dr. Flint, in his “Physiology,” gives the average male brain in New York at a little over 50 ounces. Here we find one of the most powerful of the statesmen of his time with a receding forehead and exceedingly small brain. - Leonardo da Vinci
- Leonardo da Vinci's Glider and Parachute Idea
Leonardo da Vinci, the great Italian artist and scientist, who lived in the fifteenth century, spent years experimenting with the idea of flying. He made a number of sketches of wings to be fitted to the arms and legs of man. His plan for a parachute was soundly worked out and his idea that the wings of a flying machine should be patterned after the wings of the bat found expression in the doped fabric covering of our early airplanes. - Leonardo Da Vincis diagram of the heart

Living in chinks and crannies of ranges in our homes, and occasionally in bookcases and closets where glutinous and sugary matters abound, but which has probably not been met with elsewhere, is a strange but beautiful little creature which, as far as can be determined, goes through the brief round of its existence without a name to distinguish it from its fellows. Few entomologists have given any special attention to its family relationships. The possession of certain bristle-like appendages which terminate the abdomen, and which are no doubt comparable with the abdominal legs of the Myriopods, or Thousand Legs, classes it with the Bristle-tails, or Lepismas. In general form, a likeness to the larva of Perla, a net-veined neuropterous insect, is manifest, or to the narrow-bodied species of Blattariæ, or Cockroaches, when divested of wings. - Let the mathematics professor demonstrate the lesson for us

- Letting his feet breathe
Walking-shoes should not be worn in the house, neither should the same pair be worn on consecutive days, thus giving them a chance to air. Abraham Lincoln used to slip off his shoes when he had the chance, “ letting his feet breathe,” as he said. - Leucadendron Stokoei

Leucadendron Stokoei - Leupold's Engine
In 1725, Jacob Leupold invented an engine, in which the work was done by steam alone, instead of by the atmosphere, as in the engines that immediately preceded it. Leupold used two cylinders. They were open at the top to the atmosphere as in the others, but154 he used higher pressures of steam, and arranged a four-way cock between the bottoms of the two cylinders in such a way that the bottom of each cylinder, in its turn, was connected to the boiler or to the open air. Each cylinder actuated directly a separate vibrating beam, which in turn actuated the piston of a pump; the two pistons acting reciprocally, each drawing up water in its turn. In 1765, James Watt made the very great improvement of providing a condenser separate from the cylinder of the engine, so that the great loss of heat caused by cooling the cylinder and then heating it at each stroke was wholly avoided. He covered the cylinder entirely, and surrounded it with an external cylinder kept always full of steam, that maintained the cylinder at a high temperature. The steam, instead of being condensed within the cylinder, after it had done its work, was allowed to escape into the condenser. To facilitate this action, the condenser was fitted with an air-pump that maintained a good vacuum in it. In 1769, Watt invented an improvement that consisted mainly of means whereby the supply of steam to the cylinder could be shut off at any desired part of the stroke, and the steam allowed to complete the rest of the stroke by virtue of its expansive force. This invention increased tremendously the efficiency of the engine: that is, the amount of work done with a given amount of steam. - Levee and Great Bridge at St. Louis

- Life in an Earth Lodge
The small lodges we built for winter did not stand long after we left them in the spring. Built on low ground by the Missouri, they were often swept away in the June rise; for in that month the river is flooded by snows melting in the Rocky Mountains. The loss of our winter lodges never troubled us, however; for we thought of them as but huts. Then, too, we seldom wintered twice in the same place. We burned much firewood in our winter lodges, and before spring came the women had to go far to find it. The next season we made camp in a new place, where was plenty of dead-and-down wood for fuel. We looked upon our summer lodges, to which we came every spring, as our real homes. There were about seventy of these, earth lodges45 well-built and roomy, in Like-a-Fishhook village. Most of them were built the second summer of our stay there. - Life in the Early Palæozoic
