AND PHARMACOrCEIA. 475 



England growing in hedge rows. Some preparations of elder 

 have cathartic qualities, but are not deserving of attention by 

 the Veterinarian. The chief use of elder is to form an oil, of a 

 greenish hue, and of little or no use ; and an ointment, which 

 serves the same purpose as hog's lard in the composition of 

 unguents. The oil is prepared from the leaves, the ointment 

 from the blossom of the tree. There is also a distilled water 

 made from it, which is often employed in the composition of 

 eye-waters, but does not appear to possess any medical qualities 

 that do not exist in simple or distilled water. 



ELECTRICITY. The operation of electricity is performed 

 on the human being in those disorders which require stimulant 

 applications, as in paralysis. It likewise rouses the action of 

 the absorbent system in a very remarkable degree, and on that 

 account is sometimes employed in cases of indolent tumours, 

 I am not aware that this remedy has been adopted by veterinary- 

 practitioners, but can see no objection to its employment. 



EMBROCATIONS. External applications in a liquid 

 form that are rubbed on a diseased part, as in strains and in- 

 dolent swellings, and as an auxiliary in the treatment of in- 

 ternal inflammation. They are of a stimulating nature, and are 

 greatly assisted by friction. Of this kind are opodeldoc, soap 

 liniment, &c. 



MUSTARD EMBROCATION. 



For itiflammation of the lunr/s. 



Flour of mustard 4 ozs. 



Liquid ammonia \^ ozs. 



Oil of turpentine 1 oz. 



"Water, a sufficient quantity to bring it to the consistence 

 of cream. Flour of mustard mixed into a thin paste 

 with water only is a powerful stimulant, and may be 

 emjiloyed with good efiect in cases of internal inflam- 

 mation either of the bowels or lungs. 



Embrocations for hard indolent tumours. 



No. 1. Olive oil 4 ozs. 



Camphor 4 drs. — ]\Iix. 



No. 2. IMercurial ointment 2 ozs. 



Olive oil and camphor, of each... 2 drs. 



Embrocations of a more stimulating kind are sometimes em- 

 ployed in swellings of the joints, old strains, or other local af- 

 fections, such as soap liniment with liquid ammonia, olive oil, 

 oil of turpentine, and liquid ammonia ; but blisters in such cases 

 are generally more effectual.
