important. Washing animals with various carbolic preparations is 

 advisable and there are special cattle dips, horse and dog washes prepared 

 and sold. For cattle and dogs, the insecticide known as crude oil emul- 

 sion is a safe and simple application, killing all forms of life in the skin 

 and improving the condition of the coat. This emulsion mixes in water 

 to any strength and can be worked well in ; it can be left to dry on or 

 be washed completely out of the skin with a little water. For some 

 animals it is far better than carbolic preparations, which should not, 

 for instance, be applied to dogs at all. 



Lice. 



"What are generally termed lice are insects belonging to two 

 distinct orders, the biting lice (Neuroptera) and the sucking lice (allied to 

 Hewipterd). The former are small insects, found upon the hair of 

 domestic animals and in the feathers of birds. They do not feed upon 

 blood but upon hair, flakes of skin, etc. Birds rid themselves of these 

 pests by taking dust baths, rolling in the dry dust which penetrates the 

 feathers and is believed to check the lice. Sucking lice are small 



flattened insects without wings 

 found upon the hair of pigs, 

 goats, cattle, buffaloes and other 

 animals. They extract the blood 

 by means of a fine suctorial beak 

 which is barbed, and their 

 continued presence causes sores. 

 These are included among the 

 horrible creatures which infest 

 the skins of human beings, parti- 

 cularly of those of uncleanly
