THE EFFECT OF IODINE ON FARCY AND GLAN- 
DERS, IN THE OPINION OF THE FRENCH VE- 
TERINARY SURGEONS. 
I promised, at the close of the leading article in the last 
number of The Veterinarian, to inquire into this. The 
first account which I find of the employment of iodine in vete- 
rinary practice, was in 1819, on the horse, by M. Mayor, M.V. 
at Geneva. The syndic of that city had a horse with bronchial 
inflammation and enlargement of the thyroid glands ; a rare 
disease in the horse, one which I never saw, but that is re- 
corded by veterinary surgeons well worthy of credit, and may 
be readily supposed to exist in such a locality. In the dog and 
in the swine it is common enough. There is said, in this case, 
to have been an indolent tumour arising from an enlargement of 
one of the thyroid glands. Mr. Mayor commenced with giving, 
three times in the day, three drops of the tincture of iodine, 
which he rapidly increased to twelve. In three weeks the 
enlargement had disappeared*'. 
In 1824 it was used both under the form of ointment and 
tincture for goitre in the dog, at the veterinary school at Lyons, 
and with perfect success^. 
In 1825 it was used in the form of ointment of the hydriodate 
of potash by M. Prevost, in three cases, and with success, at 
Geneva ; but it is not said on what animal ; and in 182G it was em- 
ployed by the same gentleman on some dogs, and still with success. 
In June 1826, it was applied, by the same gentleman, in the 
form of an ointment composed of 3iss of hydriodate of potash, 
and §j of lard, for enlarged glands under the jaw — probably the 
submaxillary glands. These diminished to a certain degree, 
but became harder and stationary. 
In November in the same year a similar ointment was well rub- 
bed into the same enlarged glands in another, and adhering to the 
jaw. In ten days the enlargement entirely disappeared^. 
Thus far the iodine appeared to have power over the thyroid 
glands, supposing it to have been an affection of these glands ; 
but there was an uncertainty with respect to the submaxillary 
glands. It caused their dispersion in the second case — it only 
diminished them in the first. 
In 1827, under the management of M. Jacob, several hard
