External and Internal Parasites of Animals. 245 



dip as for scab, using such materials as creolin, germol, 

 chloronaphtholeum, etc., and repeat the dipping in two 

 weeks' time, thus allowing time for the nits to hatch out, 

 when the new lice can be destroyed; ticks of sheep need 

 the same treatment, usually given by the best shepherds 

 shortly after shearing. Cattle need the application of 

 creolin and water (one to twenty), melted lard and kero- 

 sene (two to one) or the kerosene emulsion made as fol- 

 lows: 



One-half pound hard soap and one gallon of water, 

 boil until the soap is dissolved, then add tw r o gallons of 

 kerosene (coal oil) and mix thoroughly; when about to 

 use take one part of the emulsion to four to eight parts 

 of the water; in place of the hard soap, whale oil soap or 

 one quart of soft soap may be used. 



Ringworm is a contagious disease due to a fungus found 

 on man, horses and cattle; it often dies out of its own 

 accord. This disease, as the name implies, shows itself 

 by bare ring-shaped patches, in which the hairs are seen 

 to be broken off close to the skin, on some spots the hairs 

 are split at the ends or are dead. The parasite often 

 affects the skin around the eyes of cattle, and in some 

 cases will spread over the neck or on parts of the body. 

 The affected parts should be well washed with soapsuds, 

 using a brush to remove any of the dead skin scales, 

 then follow with one of the following ointments, one being 

 as useful as the other : 



Salicylic acid 1 part, 



Clean sweet lard « parts, 



or 



Iodide of sulfur 1 part, 



Lard « parts,
