induce convulsions. Dogs, besides, exhibit imperfect power 

 of controlling the movements of their limbs, and when the 

 doses amount to three or four drachms insensibility and 

 death ensue. The vapour of camphor destroys fleas, bugs, 

 moths, and spiders, exciting, enfeebling, and stupefying 

 them. It has considerable antiseptic power. Koch found 

 that one part to 2500 of water hindered development of 

 anthrax bacilli. 



MEDICINAL USES. Camphor is used, especially in young 

 animals, as a gastric stimulant and antiseptic. In diarrhoea 

 it is given with aromatics and a few drops of hydrochloric 

 acid, or with ether and laudanum. Robertson prescribed it 

 with opium in enteritis in horses. Many veterinarians give 

 it freely in catarrhal cases presenting increased secretion 

 of bronchial mucus and dyspnoea, conjoining it with salines, 

 ammonia salts, and belladonna. For chronic bronchitis in 

 horses, it may be prescribed with squill, and in convalescence 

 from catarrhal complaints with gentian, ginger, and iron. 

 For exhausting disease, whether in horses or cattle, a stimu- 

 lating draught is often made with two drachms each of 

 camphor and ammonium carbonate, and an ounce of ether, 

 given in ale or cold gruel. In equine pneumonia, influenza, 

 or other disease associated with increasing prostration, 

 camphor is of great value. Three to five drachms of 

 25 per cent, camphorated oil or ether may be injected sub- 

 cutaneously every three hours. To avoid local irritation, 

 the second, third, and following injections should be made 

 a short distance from the preceding puncture, and not more 

 than 75 minims should be injected at one point. Sore- 

 throat and irritable, spasmodic cough are relieved by placing 

 on the tongue, at intervals of two or three hours, or as 

 required, an electuary made with equal parts of belladonna 

 extract, borax, and camphor, reduced to a paste with 

 ammonium acetate solution, and mixed with eight or ten 

 parts of honey or treacle. Small doses prescribed with 

 belladonna lessen urino-genital irritability, resulting from 

 cantharides or other causes. It does not, as has been 

 popularly believed, diminish the lacteal secretion. 



For dogs, a mixture containing grs. v. each of camphor 

 and belladonna extract, with f3J- of ammonium acetate
