CASEATION. 591 



across the middle of the lower surface of the tumour, from 

 oue extremity to the other, in such manner as to destroy, as 

 much as possible, any surrounding adhesions the cord may 

 have contracted, without risk of wounding its vessels. This 

 will enable us to get at the neck of the tumour, around 

 which is to be fastened our ligature, tight enough to inter- 

 rupt the circulation. Over this is to be placed a second 

 ligature, furnished with a slip-knot, with its end brought out 

 of the external wound, and so adjusted that it may be 

 tightened after suppuration has commenced. Some veteri- 

 narians who have been desirous to employ clams in these 

 cases, have had curved clams made. Chabert directs us to 

 have a leaden ring constructed for the cord, which can be 

 contracted at pleasure. Mathieu uses a sort of pincers of 

 his own invention, or else a ligature so disposed that it acts 

 only upon the blood-vessels. 



In the treatment of scirrhus, when once it has extended 

 along the cord, as high, perhaps, as the loins, quite out of 

 the reach of ligature — a fact that may be ascertained by 

 manual examination per^ rectum — and the cord itself is found 

 to be indurated, and increased in volume upwards, and has 

 contracted adhesions with the surrounding parts, and is 

 likely to degenerate into a cancerous mass, in its extent from 

 the scrotum to the loins, other means must be sought. One 

 resource is left us — that of piercing or boring the cord with 

 a red-hot iron, of sufficient length and straightness, and 

 about the diameter of the finger. The scirrhous cord is to 

 be drawn forth, to the extent that it will bear, by an assis- 

 tant, who at the same time diverges the lips of the wound, 

 while the operator plunges the cautery into the scirrhous 

 substance, and thrusts it longitudinally through it. At the 

 same time he may, if he likes, cauterise its sides, both within 

 and without the scrotum : the object being to induce a 

 suppurative process which may in the end consume it. From 

 time to time the eschars and concretions of matter will 

 require removal, and the parts cleansing. 



At the Toulouse Veterinary School, an enormous champignon, the
