ally the collection becomes more limited and finally disap- 

 pears. Incision, followed by careful disinfection, is much 

 recommended by all practitioners. Blisters and setons should 

 be absolutely abandoned, in spite of some good results which 

 have been claimed. 



For oleaginous effusions, Violet and Gavard have used 

 irritant preparations, liquid caustics and actual cauteriza- 

 tion, and claim they have good results. 



In the ox Furlanetto obtained a complete cure by pass- 

 ing a ribbon seton through a tumor and smearing it every 

 four or five hours with an ointment of bichromate of pot- 

 ash, I to 8. 



BURNS. 



Burns are lesions produced by the action of heat. They 

 may be caused by solid bodies, by gas raised to a high tem- 

 perature or by chemical caustics. 



ETIOLOGY. — Of all the domestic animals the horse is 

 most exposed to burns. In the ox they are more rare. The 

 cat and the dog, being in constant close relation with man, 

 are, like him, exposed to burns by oil or by boiling water. 

 Independent of these conditions, which refer to the mode of 

 utilization of animals, it is indispensable to add that death 

 by burns or by asphyxia frequently occurs in burning build- 

 ing's. In these events the animals seldom succumb to actual 

 burning. In nearly every instance they are asphyxiated by 

 gases before the flame has reached them. The irritating 

 fumes also cause coryza, laryngitis and even bronchitis and 

 pneumonia, which the subjects find difficulty in resisting. 



Solid bodies do not inflict very extensive burns, as their 

 effect is confined to the parts they touch. Shoes applied 

 too hot to the foot often cause burns of the sensitive sole, 

 and even the cautery when used for curative purposes may 

 cause serious accidents. 



Liquids by spreading over the skin produce large burns,
