OINTMENTS. 279 



Ointments. 

 Blistering Ointment. — Take of Spanish fly in pow- 

 der, one drachm; hog's lard, six drachms: mix. This is 

 the ordinary blistering ointment. The old formula is one 

 of the fly to four of lard. The weaker ointment answers 

 the best purpose. 



Red Iodide Ointment. — Take of bin iodide of mer- 

 cury one drachm, hog's lard, one ounce mix. This is the 

 most useful ointment the veterinary surgeon can use, or 

 possess, for the cure of splints, ringbones, spavifes, indu- 

 rated or hardened tumors, and for the reduction of en- 

 largements of the glands of the neck. Iodide ointment 

 should only be used once in five days, or till the efiects of 

 the previous application have subsided a good deal. This 

 precaution is to prevent a blemish being made by the hair 

 falling ofi" and not growing again, which should always 

 be avoided. 



Green Ointment. — Take of simple cerate or oint- 

 ment, one ounce; and add one drachm of verdigris (diace- 

 tate of copper) and mix. This ointment will heal sores 

 when other applications have failed. 



Sulphur Ointment. — Take of iodide of sulphur, one 

 drachm; hog's lard: one ounce, mix. Used in mange and 

 skin diseases. 



Zinc Ointment. — Take carbonate of zinc, one drachm; 

 hog's lard, one ounce : mix. ^ A good healing ointment. 



Liver of Sulphur Ointment. — Take of liver of sul- 

 phur, one drachm ; hog's lard, one ounce: mix. Used in 

 mange and other skin diseases. A more cleanly and 

 easily managed form, performing all its actions, will be one 

 part of the liver of sulphur to eight parts of water.
