290 Diseases of Cattle. 



orifice ; or lie will put a plaster at the base of the horn. But 

 iu fact, the temperature of the horn is low on account of the 

 general poverty of the blood, and these measures are vain. 

 Thouo'h we have been familiar with cases of this disease 

 from boyhood, we have never seen one where the horn actu- 

 ally was hollow ; though that this might not happen through 

 the processes known as atrophy and absorption of the inner 

 vascular structure, we do not deny. Later symptoms of the 

 disease are swellings under the jaws and about the navel, and 

 dropsy of the belly. 



Treatment. — This is suggested by what has been said of 

 the causes of the disease. The animal must be well fed, 

 well housed and well cleaned. The food should be given in 

 small quantities and often. If lousy, as is very often the 

 case, it must be washed and some of the insecticides recom- 

 mended for that purpose must be applied. 



No boring or bleeding is needed. It will not be amiss to 



commence with a moderate dose of salts or oil, to clean out 



the bowels. The diarrhea, if persistent, should be checked by 



astringents. After this, a tonic is needed, especially an iron 



one, in small doses, to aid in enriching the blood ; and with 



it may be very advantageously combined a little nux vomica, 



to stimulate the nervous system, as : 



No. 322. Sulphate of iron, 2 drachms. 



Powdered nux vomica, 1 drachm. 



Powdered gentian, 1 ounce. 



This amount daily in dry food or as a drench. 



After one week it should be suspended for a week, and 

 then resumed for one week more. These measures will cer- 

 tainly cure all. cases of hollow horn that do not depend on 

 some serious organic disease.
