The American reformed horse book, a treatise on the causes, symptoms, and cure of all the diseases of the horse, including every disease peculiar to America, also breeding, rearing, and management . and other mountainr us countries borderingtltereon, it is a disease very often met with. Th« nncastrated animals seem to suffer most. After thf y jre* 104 DADOS VETERraABT MEDICINE AND SURQERr to be about eight years of age, the tumors acquire such m£gni>tnde that they press on the vocal organs, so as to decrease thecaliber of the larynx, and thus the animal becomes a from what we know of the disease in the human suoject,the glands, while undergoing enlargement, do not occasion muchpain. The danger arises from mechanical causes, and the deathof the subject, if it occur, is due to asphyxia, or horses there are very few fatal cases on record. Thareverse is the case as regards sheep. When these glands aremnch enlarged, and the animal is near or past the adult age, itis very unsafe to attempt their removal by means of the knife;for at this stage they are highly vascular, and the arteries whichran into them are much enlarged. The operation has been sno-. ?floviiK TSB mtoa or bbohosckiklk ih the ebgiok or mm tvboav. uMofuUy performed on lambs, but it must be done when they ai«quite young, and the artery must be secured before the gland iaextirpated, or the animal will bleed to death in a few seconds. Itis well known among the members of the profession that the dia-ease is incurable; and the same remarks apply to all hereditarydiseases, yet the growth of the glands may be retarded by meantof local and constitutional treatment. The thyroid glands are two ovoid bodies, varying in size from? filbert to an egg, located in the region of the thyroid cartUag«(throat), one on each side of the trachea (windpipe). Their at-taohmentB are cellular. When cut into, they exhibit a poms tex-ture, highly vascular, well supplied with blood-vessels. VeryliMi
