With the older animals, so far as my experience at present teaches me, the thyroid body, when enlarged, has not suddenly increased; yet this fact by no means proves that the diseased part is always quiescent, and cannot increase in size. Because of this possibility, and the safety of the process, the disease should be eradicated. This is to be done by administering iodine by the mouth, and painting over the enlargement (having the hair first closely shaved off the part) with some of the tincture of the same drug, applied by means of a camel's hair brush. As iodine soon separates and is thrown down to the bottom, all the preparations of it should be used as freshly made as may be convenient. The mixture of which iodine is the active ingredient, and which is a week old, may be confidently said to have lost the major part of its virtue. Every three or four days this medicine should be concocted; for even when put into pills, iodine, being very volatile, will evaporate. The quantity to be given to the dog varies, from a quarter of a grain four times a day to the smallest pup, to two grains four times daily to the largest dog. The tincture used for painting the throat is made with spirits of wine, an ounce; iodide of potassium, a drachm.
