cases the skin should be thoroughly washed with 

 soap and water, both before and after anointing. 

 The animals should always be confined till they are 

 quite free from the disease. 



In the Edinburgh INIedical and Surgical Journal 

 for July, 1820, the following remarks are made on 

 poisoning cows, by the improper application of to- 

 bacco and corrosive sublimate in cases of the mange: 



' For the mange in five cows of Mr. Hatchett, a 

 man, vulgarly called a beast-leech or cow-doctor, 

 applied a preparation containing tobacco and corro- 

 sive sublimate. In the course of one hour and a 

 quarter, they all died, preceded by convulsions. 

 The facts were proven on an action against this 

 doctor, to the satisfaction of the jury, who awarded 

 the damages. An experiment has been subsequent- 

 ly made by an intelligent medical practitioner on 

 the diseases of dogs, in which six grains of shag to- 

 bacco, infused in about one drachm of water, being 

 applied to the skin of a dog, presently killed the 

 animal. It is, however, well known that dogs are 

 very commonly waslied with tobacco water for the 

 mange, without poisoning them ; but I have known 

 it occasion long continued nausea, vomiting, purg- 

 ing, and discharge of urine. Probably, however, it 

 requires a concentrated solution of tobacco to prove 

 destructive to life. The same observation is made 

 on the effects of corrosive sublimate and tobacco in 

 the case of jMr. Hatchett's cows. Probably, too, 

 these applications may have occasionally produced 

 death, but the cases were unnoticed. It is also 

 questionable, whether the tobacco or corrosive poi- 

 soned the cows or the two conjointly. Tobacco 

 does not kill horses, for it is veiy commonly eaten 

 with corn, to increase the appetite, nor do very 

 large doses of corrosive sublimate taken internally 

 poison them.'
