also been relieved by the inhalation of this gas. This is 

 well worthy of a fair trial, and if it but accomplish half 

 what is claimed for it, a great and cheap fumigation and 

 disinfectant is now within our reach. But, bear in mind 

 still, that it is a poisonous gas, and to prevent this effect, 

 have free ventilation through the whole place. 



Sulphate of Zinc. — White Vitriol — This is a valua- 

 ble article for healing wounds and sores. Not ad- 

 ministered internally to aiiy animal, except as an emetic 

 to dogs. As an external wash for sores, one part of zinc 

 to twenty of rain water, will answer for most purposes. 

 For eye wash, three to four grains to the ounce of water, 

 is one of the best applications which can be applied to the 

 eye, in cases of purulent ophthalmia. 



Tannate of Glycerine. — An excellent application 

 to the eyes, in purulent opthalmia, and to moist sores, 

 wherever situated upon the body. 



Tannin. — This is the acid of barks, and is valuable, 

 mixed with water, in running ulcers and sores, and in 

 diarrhoea, in all animals. The powder sprinkled upon 

 bleeding sores, will in many cases stop it. One drachm to a 

 pint of cold water makes a good eyewash, and in many cases 

 dries up the scum, and removes it altogether. It is certainly 

 a cheap and useful remedy, and can do no harm to the eye. 



Doses. — For horses and cattle, in diarrhoea, the dose 

 of tannic acid is from half to one drachm, given in gruel 

 as a drench. For calves with the same disease, give 

 from ten to twenty grains as a dose, mixed with wheat 

 flour gruel. Snuffed up the nostrils by man, in bleeding 

 from the nose, it will in most cases arrest it at once. 



Tannin of Keameria. — This is used for the 

 same purpose as the preceding, but it is a better stypic, 

 or arrester of bleeding from the skin or sores.
