PNEUMONIA 141 



mustard plaster. We make this mustard plaster by 

 stirring a pound of powdered mustard into a thin 

 paste with hot water, which is then rubbed briskly 

 into the hair over both sides of the thorax and along 

 the course of- the trachea from the larynx to the breast. 

 This application causes only slight irritation in cattle 

 and lasts for about a half hour, during which the ani- 

 mal usually trembles a little and paws some with one 

 foot or the other. 



We make no attempt to remove the mustard after 

 it has served its purpose, allowing it to dry and come 

 off of its own accord in time. Medical treatment we 

 limit to one dram each of fluid extracts of nux vom- 

 ica and gentian root every few hours during the day. 

 If a cough is present we add to this a quarter dram 

 of fluid extract of belladonna. On the first day of 

 treatment, and again on the fourth day, we inject a 

 dose of polyvalent bacterins hypodermically. 



If the appetite is very much below par we double 

 the dose of the nux vomica until the cow eats; then 

 reduce it to one dram again. We see to it that the 

 patient is stabled under hygienic conditions and sup- 

 plied with tempting feeds. Really, the best index to 

 the condition of a bovine patient suffering from pneu- 

 monitis is the appetite. If the veterinarian can con- 

 trive to keep the patient eating regularly and quite 

 heartily he is doing well. 



The foregoing comprises the sum total of our treat- 

 ment in pneumonitis in cattle. We pay no attention 

 to reducing the temperature with coal-tar prepara- 

 tions or other febrifuges. If the temperature persists 

 at a dangerous height, we find the administration of 

 intestinal antiseptics most serviceable. When con- 

 fronted with this state of affairs we give a few large 

 doses of sulpho-carbolates compound, usually about
