of one side. Fig. 1208 represents the liver- 

 fluke fully matured. 



A species of this animal, called the lance- 

 olated fluke, is shown in Fig. 1209. 



There is a non -parasitic order of creaturei* 

 inhabiting ponds and ditches, termed plan- 

 arians, which is so much like the fluke in 

 appearance that we present an illustration 

 of the former in Fig. 1210. They, like the 

 fluke, very much resemble leeches, not only 

 in appearance, but in habits. 



The fluke throws off several thousand eggs, 

 that pass out with the feces. In a freshet, 

 immense numbers of these worms are left 

 on the meadows, and the sheep eating them 

 with grass, the miniature fluke passes down the main intestine, un- 

 til it reaches the liver duct, which it as- 

 cends, and at once begins its development. 

 In England 2,000,000 sheep died of this 

 disease in 1830. Fig; 1211 represents a 

 sheep affected with this terrible disease.
