INTESTINAL WORMS. 



LUNG AND BRONCHIAL WORMS. 



Many an owner of lambs finds them slowly pining away from some 

 mysterious Disease for which he cannot account. The skin becomes pale, 

 as if the blood had disappeared; the young creatures waste and pine 

 away and gradually die; and this peculiar slow death has given the 

 common name of "pining" to this disease, which is exceedingly 

 prevalent in districts where sheep are kept numerously. 



The cause of it is the presence in the air passages of the lungs and 

 the windpipe of countless small white worms, like fragments of 

 thread, which, by their irritation, eause these air passages to be filled 

 with froth and mucus, interfering with the supply of air to the lungs 

 and gradually impoverishing the blood. Not only lambs, but young 

 calves, pigs and chickens are also infested with similar worms, which 

 produce the same effect, in every case, however, resulting in death, 

 unless some remedy is found. Kemedies, however, must be sought 

 from competent sources, and beyond suggesting that sulphur or tur- 

 pentine, both of which are readily absorbed into the blood and spread 

 through the whole system, are generally used with good effect as a 

 remedy, we confine ourselves here to what we know as regards pre- 

 vention of the trouble from this pest. It is well known that when lambs 

 and calves are pastured on fields where old sheep or poultry have 

 run, they are sure to be affected, and that chickens that are kept 

 among old fowls, or on ground that has been fouled by the old 

 Thirds, invariably have this disease, which is known in their case as 

 ""gapes." The way of prevention, then, is obvious: never let young 

 animals run for pasture where older ones have been kept, for the 

 simple reason that the droppings of these animals contain the eggs of 

 the worms which exist in their intestines, and which mature and die 

 and are discharged, with the innumerable eggs contained in their 

 iDodies. These older animals, being more robust, are not annoyed 

 with the worms, although in some cases these may produce diseases 

 of which the cause is not suspected. 



INTESTINAL WORMS. 



Farm animals suffer exceedingly from intestinal parasites, which 

 are so numerous as to almost defy description. There is not an 

 organ of importance in the body which is not more or less infested 

 with them. The liver, the kidney, the bowels, the kidney fat, the 

 heart, are all subject to attacks by these pests; while one particular 

 worm known as Trichina Spiralis (see engraving) is so common among
