 limits of the affected gland. Tumors, both benign and ma- 

 lignant, very frequently develop in the mammary glands of 

 mares, cows, bitches and sows. In fact these organs are 

 relatively more susceptible to tumors than any other part

 application, ablation is the only choice. Extirpation of 

 tumors that transgress into the glandular tissue, without 

 sacrificing the whole gland, is always an imprudent inter- 

 vention, because of the certainty of recurrence in the case 

 of malignant neoplasms, and because in the case of benign 

 growths the partially removed gland will behave badly at 

 each new period of lactation. 



In meat producing animals parts of a. mamma invaded 

 by a new growth may be removed, preparatory to fatten-

 working purposes total ablation of the affected gland and 

 all of the integument implicated, should be at once per-
