THE EFFECT OF IODINE IN GLANDE11S. 
tumours disappeared from the udder of a mare, through the 
influence of the same ointment*. 
It was about the same time discovered, that some cases which 
had resisted the power of the hydriodate of potash, yielded to 
the ioduret of mercury. The general feeling, however, was in 
favour of the hydriodate of potash ; and, as years passed on, it 
began to be more and more established in the good opinion of 
the medical publicT. 
M. Leblanc next entered the field, and exposed several glan- 
dered horses to the influence of an atmosphere containing a 
certain portion of chlorine. The experiments were interesting, 
and shall at some future time be recorded. 
He continued the inhalation of the chlorine for a considerable 
period, and he gave iodine in doses of six grains daily of the 
mineral. The enlarged glands diminished, but the ulceration 
within the nostril was increased ; a high degree of inflammation 
being excited by the constant presence of this irritating gas. 
He then determined to lessen the quantity of the chlorine, and 
sometimes to suspend it, and the following is the account of his 
experiments, and those of two other gentlemen to whom he was 
united in commission by the legal authorities. 
April 10th, 1828. — A Normandy mare, seven years old, lame 
from navicular disease, had eight chancres in the left nostril — 
swelling of the venous plexus on the same side — discharge from 
the left nostril adherent to the nostril, and the intermaxillary 
gland on the same side enlarged. 
During fifteen days he used fumigations of iodine for the nostrils, 
and an ointment composed of hydriodate of potash four drachms, 
pure iodine one drachm, and lard sixty-four drachms. But 
the salutary changes in the nostril not being so marked as under 
the influence of chlorine, he finally had recourse to the chlorine. 
After forty days’ treatment, the ulcers were cicatrized, the 
discharge from the nostrils had ceased, and the intermaxillary 
glands had returned to their natural size. There was no trace of 
glanders, but the cicatrices of the ulcers. She was destroyed 
ten days afterwards, and there remained only these cicatrices, 
and some miliary tubercles. 
10th May , 1828. — .Another mare, twelve years old, in good con- 
dition, but with frequent cough, entered the infirmary. She had 
four chancres on the septum of the left side, with an abundant 
discharge adherent to the nose. The maxillary ganglions were 
circumscribed (cir consents), somewhat prominent, and tender.
