DOGS! THEIR MANAGEMENT. 199 



compressed ; the little beast is dull ; the breathing is 

 very laborious ; the animal sleeps much, and at last dies 

 without a struggle, casting off life as it were but a trou- 

 bled dream. It never has perfectly enjoyed existence, 

 and its departure is not to be regretted. 



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 mix- 

 ture 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.
