Prepare as the foregoing one. Each of these valuable 

 sheep-dipping mixtures are sufficient to cure and dip one 

 hundred sheep. 



The way sheep-dipping mixtures are sometimes used is 

 far wrong, as was the case in the celebrated sheep-poisoning 

 case at Burton, England, where the animals were driven, 

 immediately after their bath, containing twenty ounces of 

 arsenic, twenty ounces of soda-ash, and two ounces of 

 sulphur, to their pasture, with their wool saturated with it, 

 and consequently dripping from the wool on the grass that 

 the sheep were just eating. 



The improved plan in dipping sheep is: First. The 

 solution or the mixture is to be put in a tub, or other 

 vessel, sufficiently large to allow the sheep (except the 

 head) to be immersed in it, without the mixture running 

 over the sides of the tub or vessel. Second. When the 

 sheep is taken out, it must be placed in another tub or 

 vessel, and the liquid pressed from the wool, and returned 

 again into the dipping vessel. Third. The sheep must 

 be kept enclosed in a sheep-fold, or other sufficiently airy 

 place, where there is no food of any kind that a sheep will 

 eat, until the wool is perfectly dry. 



Several of the veterinary professors of the Edinburgh 

 veterinary colleges, after the above sheep-poisoning case 

 occurred, instituted a series of experiments to prove 

 whether arsenical baths were dangerous, and if sheep could 

 be poisoned by immersion therein. The following is the 

 result of their experience. (" Edinburgh Veterinary Re- 

 view" for April, 1859.) 



First. That the immersion of sheep whether sound, or 

 suffering from scab, with actensive eruptions or "foot-rot," 

 with free exposure of the vascular structure of the fed, 

 in arsenical solutions, varying in strength, is unattended
