Fig. 5. — Tumor forceps of a serviceable pattern for fistula 

 operation. The style of the jaws in tumor forceps is a mat- 

 ter that should be carefully noted in purchasing such an in- 

 strument. For instance, some vulsellum forceps are so de- 

 signed that the incomplete curve of the jaws together with 

 their slender and weak construction makes them too delicate 

 for much veterinary surgical work. The instrument illus- 

 trated above is designed so that with them a firm grasp of 

 tissues is possible and a secure hold is insured. 



Fig. 6. — Drainage Tube and Inserter. 

 By means of the drainage tube inserter it is possible to in- 

 troduce a rubber drainage tube with a minimum of invasion 

 of sound tissue. This, in many cases, is an important fac- 

 tor, as it prevents needless contamination of uninvaded parts, 

 limits the area of infected tissue and possible resultant com- 

 plications and greatly facilitates the execution of this part of 

 the technic. Hemorrhage is reduced to a minimum, opera- 

 tions are completed with dispatch and, therefore, with less 

 danger of surgical shock when these appliances are employed.
