As a thermic agent, the ray was more powerful before its entrance than it was after its emer- gence. A portion of its heat is arrested, is detained in the ice, and of this portion we now proceed to avail ourselves. What will it effect ? We place a lens in front of the ice upon the screen. Now, observe this image (see lUustra tion), the beauty of wliich is still very far from the real effect. Here is one star; yonder is.
