may be given every day, or every other day, either in the evening 

 or morning." Should the horse's appetite amend, and he appear 

 going on well, after a week, ten days, or a fortnight, the dose may 

 be augmented a couple of grains ; but after another like interval 

 the medicine had better be suspended for a few days or a week, 

 when the first doses may be resumed, and after a week increased 

 to ten and twelve grains. 



Iodine (the mineral) has been exhibited by myself in farcy 

 and glanders, but with no sign of benefit from it. The iodide of 

 potassium has been given in very large doses, varying from a 

 drachm to an ounce (not, however, as a remedy for glanders), by 

 Professor Dick, but with no appreciable effect, save an unusual 

 indifference about drink. Inefficacious, however, as iodine has 

 proved by itself, in combination with copper, in the form of the 



DiNlODlDE OF Copper, it appears to have become, in farcy in 

 particular, of indubitable service. For the introduction of this 

 medicinal agent into our pharmacopoeia we are indebted to Mr. 

 Morton, Professor of Chemistry at the Royal Veterinary College. 

 " The well known fact," says Mr. Morton, " that the salts of copper 

 rank among the most valuable tonic agents for the horse, and that 

 all the mineral tonics, in order to produce their effects, are taken 

 up into the circulation, coupled with the equally well known in- 

 fluence of iodine on the absorbent vessels, first led me to think that 

 a combination of these agents would be of service in farcy. The 

 kindness of my friends, Professor Spooner and Mr. Daws, enabled 

 me to put the subject to the test of experiment, the result of which 

 fully confirmed my expectations. Since then, I have received 

 numerous communications bearing testimony to the benefits de- 

 rived from its employment, so that it has now become an esta- 

 blished article of the veterinary materia medica." — " It has been 

 found of service in farcy, chronic oedematous enlargement of the 

 legs, and those affections simulating glanders. It may be given in 

 doses from 3j to 3ij daily, combining it with the root of gentian 

 and some carminative, as pimento or Cayenne pepper. Cantha- 

 rides in small doses may be advantageously combined*." From
