...chemical, pathological and other laboratories, rooms for the curator and some of the professors, the Warren Museum, and the dissecting room, or "dead-man's hall." Of the lecture rooms, two are of double height, and in them the seats for the students rise above the lecturer in almost perpendicular tiers. In one of them is the portrait of Dr. Oliver Wendell Holmes, presented to the school by his friends, when he retired from the chair of anatomy a year ago. The laboratories are of little interest to the average man, but are the places where the students spend much...
...shoulder movement is jerky, as well as extremely tiresome. It is unnecessary work which often severely taxes an oarsman's strength. Meanwhile the arms are kept perfectly straight, (not rigid, for rigidity tires the muscles), until the body stops to reverse its motion just back of the perpendicular. At this point the arms are drawn to the chest at the rate at which the body has been swinging back; but, as soon as they touch the chest, they are shot out forward and are again held perfectly straight. This arm movement is called the "shoot" because it is rapidly executed...
...Sargent has also introduced a system of swivel pulleys in the higher weights, so that side movements can be performed without involving any lateral friction. To the sliding chains and other machines of a similar nature, the perpendicular rods which support the pulleys have been directly attached, instead of being fastened to the wall or floor as has heretofore been the case. In this way each machine is entirely independent of stationary fastenings, and, when necessary, may be easily transported. Three horizontal bars, parallel to each other, have been placed in the gymnasium. By this means a greater variety...
...left, is the only curve that can be made, for the reason that a man can't throw a ball swiftly when he holds it in position to do anything else. To get an out-curve the ball must be held in such a way that its axis is perpendicular ; that is, with the back of the hand toward the ground. When it is thrown out in that position and made to revolve from right to left the resistance of the air is strongest on the right side and least on the left. The course of the ball then naturally...
...said that the new stroke adopted by the Yale College oarsmen differs from the old one in these particulars: The reach forward is much longer, and the body is not swung so far back of the perpendicular. The slides are shorter, and on the recover the body is drawn up slower, which, it is held, does not stop the momentum of the boat as much as the quicker slide. The hands are thrown away from the body very rapidly. The oars are pulled through the water about as quickly as last year, however. Although the motions within the boat...
