of the cough. That veterinary surgeon or agriculturist would de- 

 serve well who puts this fairly to the test. 



Tliere is another mode of going to work, and one that promises 

 occasional success. There are certain drugs that are taken up by the 

 lacteals, or by some of the absorbent vessels, and carried into the 

 circulation, and produce their effect by immediate contact with the 

 part on which they operate. Thus mercury acts in various local 

 diseases ; iodine lessens the growth of many tumors ; and turpen- 

 tine is a diuretic. Turpentine is pecuHarly destructive to worms. 

 It enters into every part of the circulation : is recognizable in the 

 urine and in the breath. The turpentine faihng, it might be worth 

 while to try the eflfect of squills, or the gum benzoin, or the balsams 

 of Peru and Tolu. (See page 249.) 



Homoeopathic treatment.— :'l\\e. medicines to be employed will, in 

 a great measure, be regulated by the different stages of the disease ; 

 amongst the most useful, we shall find hryoniii alba, aconite, bella- 

 donna, phosphorus, mercurius, cannabis, spongia, &c. If the inflam- 

 mation is high, we should commence the treatment by giving aconite, 

 particularly when the pulse is high, and the skin hot and dry. Bel- 

 ladonna, when there is rattHng of mucus, distressing cough, and op- 

 pression of the chest. Bryonia, with dryness of the mouth and diffi- 

 cult respiration ; this remedy is more called for when it is apt to 

 degenerate into pleurisy. Phosphorus is particularly indicated when 

 there is reason to apprehend extension of the disease to the substance 

 of the lungs. Mercurius, when the symptoms resemble catarrh, 

 with swelling of the glands and an increase of saliva. Spongia, 

 when the affection threatens to become chronic. When the breathing 

 is very difficult, tartarus emeticus may be given ; and if the secretion 

 is abundant, sepia will be found useful ; also arsenicum is a valua- 

 ble remedy when the disease assumes an epidemic form. It is also 

 useful to administer a few doses of sulphur when the animal is to 

 all appearance recovered. If the affection has been allowed to be- 

 come chronic, the remedies most useful will be found to be spongia, 

 sulphur, calcarea, carhonica, phosphorus, causticum, silicea, arsenicum, 

 conium, stannum, (fee. 



INFLAMMATION OF THE LUNGS. 



The beautiful appearance of the lights, or lungs, in cattle, will 

 sufficiently prove that these animals are, comparatively, seldom sub- 

 ject to pure inflammation of the lungs. It has been acknowledged, 

 however, that, to a certain extent, it accompanies bronchitis ; for, 

 when the membrane of the air-passages is inflamed, it is to be ex- 

 pected that the air-cells in which these passages terminate will not 

 quite escape. 



The substance of the lungs is made up of thousands of these little
