112 The Microscope. 



2. The Vorticellce (bell-flower animalcules) . Some- 

 times double-headed, sometimes swimming freely, with 

 no stalks. 



3. The short wheel-animalcule, creeping leech-like 

 by arching its body and drawing up its foot to its 

 head, then putting its head forward, and so on. It 

 carries a pair of wheels, apparently on its head, and 

 can swim freely through the water. 



4. The astonishing, transparent, bagpipe-like 

 creature, rolling over slowly. 



5. The swan-like little creatures. 



6. The bright green animalcules, covered with 

 hairs, very common. 



7. The colourless animalcules, bean-shaped, like 

 the green, and commonest of all. 



8. Smaller colourless animalcules, also very 

 common. 



9. Animated straw-mat, very bristly, and ap- 

 parently hot-tempered, always making sudden darts. 

 Ornamented with three or four little movable commas. 

 It was sometimes to be seen in side view, darting 

 along stalks. 



10. The stiff-branched pillar, almost like a plant, 

 though resembling Vorticellce ; standing on the duck- 

 weed stalk, and occasionally moving one of its bells 

 slightly. 



11. The animated blackberries brown, however, 

 not black solemnly rolling over and over. 



12. The chain-like filaments, their links fastened 

 generally at opposite corners. 



] 3. The little wedges OH branched stems.
