passed through the dew-lap ; it produces plenty of swelling and dis- 

 charge, and rarely or never runs on to gangrene. 



Injections. — See Clvsteks. 



Iodine. — The use of this mineral is limited to a few cases, but 

 there its effect is truly admirable. It will scarcely ever fail of dis- 

 persing enlargements of the glands, or hardened tumors, whether 

 under or at the side of the jaw, or round the joints. One part of 

 hydriodate of potash must be triturated with seven parts of lard, 

 and the ointment daily and well rubbed on and round the part. In- 

 durations of the udder seldom resist its power, unless the ulcerative 

 process has already commenced. 



There is a still more important use to which this drug may be ap- 

 plied. It possesses some power to arrest the growth of tubercles in 

 the lungs, and even to disperse them when recently formed. It is 

 only since the former part of this work was written that the attention 

 of the author has been so strongly directed to this property of iodine, 

 and that he has had such extensive opportunities of putting it to the 

 test. He will not say that he has discovered a specific for phthisis 

 or consumption in cattle, but he has saved some tliat would other- 

 wise have perished, and, for a while, prolonged the existence and 

 somewhat restored the condition of more. He would urge the pro- 

 prietor of cattle, and more especially his fellow-practitioners, to study 

 closely the symptoms of phthisis, as detailed in pages 272, 273 ; to 

 make themselves masters of the inward, feeble, painful, hoarse, gurg- 

 lino- cough of consumption ; and as soon as they are assured that 

 this termination or consequence of catarrh, or pneumonia, or pleurisy, 

 begins to have existence — that tubercles have been formed, and, per- 

 haps, have begun to suppurate, let them have recourse to the iodine, 

 in the form of the hydriodate of potash, given in a small mash in 

 doses of three grains morning and evening at the commencement of 

 the treatment, and gradually increased to six or eight grains. To 

 this should be added proper attention to comfort ; yet not too much 

 nursing ; and free access to succulent, but not stimulating, food ; 

 and the medicine should be continued not only until the general con- 

 dition of the beast begins to improve, but until the character of the 

 cough has been essentially changed. 



Ipecacuanha. — This drug is used in the composition of the Do- 

 ver's, or compound ipecacuanha powder, which has been recom- 

 mended by some practitioners in the treatment of dysentery. It is 

 thus made : — " Take ipecacuanha root powdered, and opium also in 

 powder, of each a drachm, and sulphate of potash an ounce. Rub 

 them together to a fine powder." The dose is from two to four 

 drachms. This, however, is not an efficient medicine for such a 

 disease. 



Lard. — This is the principal basis of all ointments. 

 Laudakum. — See Opium.
