174 TEMPORARY AMAUROSIS DURING GESTATION. 
good condition, and in an advanced state of pregnancy, belong¬ 
ing to M. Herb—. 
I w^s sent for to examine her sight, which for some time had 
appeared to be lost, although the eyes preserved their transpa¬ 
rency and brightness. I immediately knew it to be perfect 
amaurosis. A blister was put on each cheek, the suppuration 
of which was kept up until the 10th of May ; and the eyes were 
frequently bathed with lotions composed of an infusion of white 
elder flowers and extract of lead. These means not having 
produced any amelioration, and the time of parturition being 
very near, I advised her master to suspend all further treatment 
until she had foaled, when we would make trial of some other 
remedies ; and he consented. 
The animal foaled on the 21st of May, and I did not see her 
until the 30th ; when, to my great surprise, she could see per¬ 
fectly well. Her owner told me, that the day after she had 
foaled they could scarcely believe their senses when they per¬ 
ceived that her sight was completely restored. 
CASE II. 
1 1th of June, 1825.—A seven-year old mare, in foal, near her 
time, and belonging to M. P-. 
The owner told me that this animal, which had always had 
very good sight, had not, for the last five or six days, been able 
to see at all, although the eyes appeared to be as perfect as 
ever. She had amaurosis. Recollecting the mare mentioned in 
the preceding case, I refrained from prescribing any thing, and 
advised her owner to wait until after she had foaled before he 
made use of any remedies. This took place on the 18th of 
June, and on the 20th the animal saw as clearly as she did be¬ 
fore the amaurosis had been observed. 
Some Remarks on the Use of Salt in feeding 
domestic Animals. 
There are very few agriculturists or veterinarians who do not 
acknowledge the use of salt with regard to domestic animals, 
and how advantageous it is to the farmer that the cheapness of 
this article allows him to mix it with the ordinary food of his 
cattle. Many persons, in the actual state of things, believe that 
it is economical to salt the food of their horses, oxen, and sheep. 
It is not, then, without astonishment that we read in the Specta- 
teur Militaire , and in the Journal des Haras (November 1831), 
“ that the evil effects which bad forage produces are increased
