INTERNAL PARASITES OR WORMS. 345 



For bare patches, the following may prove of value : 



5 Sod. biborat 3 j ; 



Tinct. capsici 3 j ; 



Glycerin 5 ij ; 



Aquae ad vj. 



Ft. mist. 



Sig. : Apply with friction two to four times daily. 



After a while the quantity of tincture of capsicum 

 may be increased. A very light application of glycerin 

 has also been found useful in recent cases. 



When skin disease in any form occurs between the 

 toes, it may be necessary to wrap up the feet in medi- 

 cated dressings and keep the patient quiet. 



It is most important when true sarcoptic mange occurs to 

 thoroughly disinfect the kennels and everything with which 

 the dog comes in contact. The same precautions should 

 be taken as after a visitation of distemper (see p. 379).* 



INTERNAL PARASITES OR WORMS. 



It is likely that the estimate that three quarters of the 

 whole canine race are, at some time, infested by worms, 

 and that they cause more deaths than all other causes 

 together, is about correct. To understand their preven- 

 tion and treatment, a brief account of their varieties and 

 life-histories will be necessary. 



It is true that every principal organ in the body may 

 be the seat of some form of parasite. Some of these are, 

 however, of such rare occurrence that they are mere 

 pathological curiosities, and need not be here described. 



* Modern skin specialists attribute more importance to vegetable 

 parasites than ever before ; hence the value of sulphur, etc.
