376 ON AMAUROSIS AND STAGGERS. 
On the other horse the aloes had no effect. The dose was 
repeated on the 19th, and the animal died on the 20th. • 
In the beginning of January M. B. P. was requested to ex¬ 
amine a horse whose sight had been apparently affected for 
some days. He was evidently labouring under amaurosis, and 
was completely blind. The owner then acknowledged, that in 
the preceding ten years, twelve of his horses had been affected 
with staggers. Eight had died, and three of those who survived 
had become blind. 
On the 25th of November he was consulted respecting another 
horse. The treatment adopted w^as the same, but the animal 
died in two days. Its owner had two other horses in the stable, 
one of which had gutta serena after the hoar-frost colic. 
On December 1st he saw a mare afflicted with the same com¬ 
plaint. The aloes, emetic tartar, injections, and solution of 
Epsom salts, were administered, and the animal recovered; but 
at the expiration of two months inflammation of the eyes ap¬ 
peared, which terminated in amaurosis. 
On March 1st, 1816, being near Havre, he was consulted 
■ respecting a horse with sympathetic staggers. The same means 
were adopted : the horse rapidly recovered. 
On the 30th it was observed that he lifted his fore feet higher 
than usual, that the slightest noise frightened him, and that his 
ears were in perpetual motion. On careful examination it was 
ascertained that he was perfectly blind in the right eye, and could 
see very little with the left. He was sold, and nine months 
afterwards Mr. B. P. had' an opportunity of examining him. 
‘ Amaurosis was complete in the right, but the left eye w^as merely 
sensible to the distinction between light and darkness. 
On October 15th, 1827, he visited a mare w ith sympathetic 
staggers. The same means were adopted. On the 18th she lay 
down, and w^as not ^ble to, or would not, rise. Injections were 
diligently used, emetic tartar with honey daily given, and in all 
her water Epsom salts were dissolved. 
On the 27th she was,'with considerable difficulty, got on her 
leg's; but it was not until the following; Januar\^ tn^t she had 
perfectly recovered her strength. It was then observed that the 
pupils of her eyes w^ere unnatumlly dilated, and although she did 
not become blind, her vision was evidently affected. 
M. Berger, at the conclusion, appeals to the experience of his 
brethren, and we w;ould appeal to experience of our’s, and entreat 
their communication of that experience, whether there be this 
frequent connexion betw'een staggers and partial or total blindness.
