together with blood, the larval hot feeds and develops. A last 

 moult takes place before maturity. By means of the spines the 

 maggot makes its way out of the warble-cell and falls to the 

 ground. 



" The life-history of H. bovis is not known with certainty. It 

 may be the same as H. lincata. It is said, however, to lay its 

 eggs on the upper parts of the body. According to Miss 

 Ormerod the maggots from these eggs, aided by mouth hooks 

 and spines, bore directly through the hide. These grow into the 

 mature bots and cause warbles similar to the former species. 



" Much good may be done by allowing stock to have plenty 

 of shelter during hot weather, either natural shelter of trees, 

 or artificial shelter formed by rough lodges or sheds. 



" The proximity of water, which the stock can enter at will 

 is also useful as a means of warding off the pest. 



" The flies may be deterred from laying their eggs by dressing 

 the beasts at intervals of a month, from May to September, v/ith 

 some strong smelling oil or grease. Cart grease and paraffin 

 may be used for this purpose. Another mixture found of benefit 

 is I quart of train oil, 4 ozs. of oil of tar, and 4 ozs. of flowers of 

 sulphur. 



" If animals are found to be warbled the 'bots' may be squeezed 

 out of the swellings and killed during February^ March, and 

 April. The maggots may be very easily extracted by squeezing 

 the warbles with both thumbs, and may then be squashed under 

 foot. This is a better plan than covering the opening of the 

 warble with grease or mercurial ointment, so as to suffocate the 

 bot within."

Symptoms of the Disease. — It appears that the disease is
