 Cyclops he is rightly called. Although so small 

 that we can make out little of his structure with- 

 out the aid of the lens, yet Cyclops is far from 

 being related to the other still smaller beings 

 which swim about him, many of which consist of 

 but one cell and are popularly known as animal- 

 culae, more correctly as Protozoans. Cyclops has 

 a jointed body and in many other ways shows his 

 relationship to crabs and lobsters, even though 

 they are many times larger and live in salt water. 



Another member of this group is Daphnia, 

 although the appropriateness of this name yet 

 remains to be discovered ; Daphnia being a chunky- 

 bodied little being, with a double-branched pair of 

 oar-like appendages, with which he darts swiftly 

 through the water. Although covered with a hard 

 crust like a crab, this is so transparent that we 

 can see right through his body. The dark mass 

 of food in the stomach and the beating heart are 

 perfectly distinct. Often, near the upper part of 

 the body, several large eggs are seen in a sort of 

 pouch, where they are kept imtil hatched.
