"A single muscle rarely or never contracts alone, but always in harmony with a number of other muscles. Even the simplest movement we can make requres the combined action of several muscles to carry it out. If the movement is at all difficult, such as playing on the piano or riding on the bicycle, the different muscles must contract in a certain order and with a certain strength and rapidity." — Blaisedell, 1904

"In nearly every tissue of the body there is a marvelous network of vessels, precisely like the lacteals, known as the <em>lymphatics</em>. They seem to start out of the part in which they are found, like the rootlets of a plant in the soil. The tiny roots join together and make larger roots. They carry a fluid called <em>lymph</em>, very much like blood without the red corpuscles. It is to be remembered that the lacteals are really the lymphatics which begin in the villi of the small intestine." — Blaisedell, 1904
