differs, forming from a siugle embryo large masses of cysts, which con- 

 tain many individuals capable of becoming adult. Its favorite situa- 

 tions in sheep are the liver and lungs. It may occur elsewhere. In 

 these places it forms large bladdery masses, whose nature can only be 

 definitely determined by the aid of the microscope. As this parasite is 

 also dangerous to man the bladders should be handled with care, and 

 destroyed. The treatment of dogs is the same as for the other Ucnia. 

 T(C)iia tenella, Cobbold (Plate XI, Figs. 5 and 6), which causes mut- 

 ton measles, is a tapeworm of man, and is snpi)osed to be acquired by 

 him while eating mutton through which the cysticerci have scattered. 

 The disease has not yet been noticed in this country, and having been 

 observed but seldom in Europe, is yet problematical. Mutton af- 

 fected would present little white spots as large as flaxseed scattered 

 through it. The loin muscles are most apt to be infected. E"either 

 this disease nor hydatids can at present be acconnted a disease of sheep 

 in this country.
