rpHIS is the third of Professor Elliot Smith 's
-*- Talks, and this week he will deal with the development of muscles as a means of movement, and what the cultivation of their skill has entailed, especially in the growth of the nervous system and the development of mind. He will start with the amœba. the most primitive of living creatures, which has no muscles nor any constant shape, but moves by the streaming of its substance. Drawings of the amoeba, and of the next stage in evolution, the medusa, which moves by the contraction of its muscles, appear on this page.
