and mountains of Scotland. It flowers in June, and should be 

 gathei'ed in Autumn, the green leaves alone being taken and 

 dried by a gentle heat. The principal property of Uva ursi is 

 astringent. It is given to man in ulcerations of the urinary 

 organs, as the kidneys or bladder, and has been strongly recom- 

 mended in cases of phthisis pulmonalis. It may likewise be ex- 

 hibited in most fluxes arising from debility, as menorrhagia, 

 fluor albus, diabetes, &c. I am not aware that it has yet re- 

 ceived a sufficient trial with regard to the horse ; but I am in- 

 clined to think it might be found serviceable in many cases of 

 relaxation of the solids. In chronic diabetes I should feel much 

 tempted to make use of it. It may be given in substance in 

 doses of from half an ounce to an ounce three times a day. It 

 may be detected in the urine three quarters of an hour after its 

 administration. 



ARGENTI NITRAS. Nitrate of Silver. Lunar Caustic. 

 A very powerful escharotic. This is generally used for destroy- 

 ing the exubei-ant fungous growths from ulcers. It is also em- 

 ployed in a liquid form, for the purpose of injecting sinuous 

 sores, and stimulating indolent ulcers or wounds. It is occa- 

 sionally prescribed as a tonic and antispasmodic for man ; but, I 

 believe, is seldom, if ever, administered internally to the horse. 

 (See Caustics and Escharotics.) Of course, when used as an 

 escharotic or stimulant it will require to be diluted with dif- 

 ferent proportions of water.* 



AROMATIC S. Stimulants that possess an agreeable odour, 

 such as cinnamon, cloves, &c. 



Aromatic Confection. — Confectio Aromatica. This is 

 made by triturating together, until reduced to a very fine 

 powder, two ounces of cinnamon bark, two ounces of nutmegs, 

 the same quantity of dried saffi-on, one ounce of cloves, half an 

 ounce of cardamiun seeds, and sixteen ounces of prepared shells, 

 and then gradually adding one pint of water, mixing the whole 

 until thoroughly incorporated. The combinations of aromatics 

 are stimulant, cordial, and carminative ; and, if not thought too 

 expensive, may be given to the horse in the dose of from half 

 an ounce to an ounce, dissolved in warm ale. It is a common 

 custom to administer cordials to horses after hunting or under- 

 going any great degree of fatigue ; but it should be remembered 

 that there are limits to this practice, and that when undue action 

 is excited, whether in the stomach or any other organ, it is in- 

 variably followed by proportionate depression. 



* Lunar caustic is sold in the form of sticks, one of which being inserted in 

 a quill forms a very convenient caustic for many purposes, but particularly as 

 an application to the wounds caused by the bite of a rabid dog. It forms a 

 black eschar in which the poison is absorbed, and thus rendered harmless. 

 A weak solution of lunar caustic in distilled water has been applied to in- 

 flamed eyes with advantage. See Ophthalmia. — Ed.
