stiffness of the limbs and neck ; the head is gradually stretched for- 

 ward, and the nose and tail become almost horizontal with the 

 back. 



Treatment consists of injections of warm soap-suds in the 

 bowels, administration of a physic of aloes, one half ounce to one 

 ounce, or sulphate of magnesia, two ounces in tepid water. Keep sick 

 animals in dark, quiet places. If due to a cut, inject turpentine into 

 it. Ten drops (more or less according to age) of belladonna may 

 be given twice daily. 



Vertigo. — This is a chronic disease due to the presence in the 

 brain of a parasite named cwnurus cerebralis. It is the embryo of 

 the taenia ccenurus of the dog, that penetrates there through the 

 digestive channel, and thence enters" the circulation. The symp-

 animals run, shake the head, or carry it to one side. Sometimes 

 they will turn to the right or to the left for several minutes. 



The treatment consists of a surgical operation to remove' the 

 worm from within the skull. Snow, cold water, or ice kept daily on

 to fifteen grains of nux vomica twice a day. 



NON-CONTAGIOUS SKIN DISEASES. 



Eczema. — A vesiculous disease, sometimes mistaken for scabies. 

 Bad food, want of exercise, and atmospheric influences, are said to 

 be occasional causes, especially in the young subject. The vesicles 

 are agglomerated, and a sero-purulent fluid exudes from them. 

 There is sometimes fever. When it passes to a chronic form, it is
