278 THE MANAGEMENT AND DISEASES OF THE DOG. 



serous fluid ; and it sometimes happens during life, from in- 

 flammation being created in tlie substance of the tumor, that 

 this cystic fluid becomes purulent, the sac ruptures, and de- 

 generates into a common, unhealthy, subacute abscess. Ex- 

 cision is, even under the circumstances, still advisable; for 

 even if we get it healed, and the tumor still remains, absorp- 

 tion is out of the question. Fibro-cystic tumor is usually 

 present in '' capped elbows." Removal by excision is simple, 

 and is followed by no ill effects. When they occur in con- 

 nection with the hocks it is more advisable to use outward ap- 

 plications. I have found iodine the best agent. 



Calcareous J'umor. — This description of tumor is most fre- 

 quently found in the vicinity of glands. In the dog, it is gen- 

 erally seen in connection with the fibrous tumor of the mam- 

 mary gland. In long-existing cases, the latter is often entirely 

 supplanted by the former. 



Treatment. — As in the two former, excision is the only ad- 

 visable treatment, except when the deposit takes place in 

 situations other than the mammary gland, and where it would 

 be impossible, with safety, to use the knife. Counter irritation, 

 or the daily application of iodine, would then be indicated, 

 but absorption in such cases is hopeless. 



with blood. This fluid, under the microscope, was found to contain a large 

 quantity of cholesterine, with exudation — corpuscles and blood-discs. In 

 the interior of the cyst which was last opened, there was a small detached 

 tumor of the size of a chestnut, smooth on the surface, and quite firm in 

 texture. To the interior of the walls of the two cysts were altached small 

 tumors, varying in size from a pea to a hazel-nut, and on the surface of the 

 lining of the cysts a quantity of flocculent white matter was deposited." 



Three accompanying microscopic illustrations are given to convey an 

 idea of the structure of the morbid growths, which were all composed of 

 the same elements. It is further observed : " It is obvious that the 

 morbid growth originated in disease of the structures of the true skin, 

 probably the result of an injury." 



I recently removed a fibro-cystic tumor the size of a hazel-nut from 

 a fore-toe of a small black-and-tan terrier. Placing- a ligature round 

 close to its attachment, I drew it sufficiently tight to sever it at once ; 

 the hsemorrhage, which was excessive for the situation, I stayed with 

 cauterv.
