AT WHAT TIME HORSES SHOULD BE LET BLOOD. 535 
tion was scarcely visible, his pulse imperceptible, and the heart’s 
action exceedingly weak. The second brother had vomited blood 
several times, but he experienced less abdominal pain than the 
others. In the little boy, the globes of the eyes were turned up¬ 
wards, the lips livid, and the pulse scarcely sensible. Lastly, 
the symptoms in the little girl were the mildest of all. M. Sied- 
ler suspected at once that these accidents were occasioned by the 
use of a certain quantity of goose-grease, which had been em¬ 
ployed in the preparation of some meat, of which the four patients 
had eaten shortly before the symptoms began. An emulsion 
containing hyoscyamus was prescribed, and on the 9th of April 
all had recovered.

The vomited matters were subjected to chemical analysis: they 
were strongly acid, but contained no metallic poison ; but the 
following facts induced Dr. Siedler to attribute the illness to the 
effects of sebacic acid. The lady of the house had made use of 
goose-grease to dress some veal, and all the persons who partook 
of the dish fell quickly sick; the lady herself, who had barely 
tasted it, felt it so disagreeable that she took no more. None of 
the grease which was suspected to have caused the accident re¬ 
mained for examination, the pot which contained it having been 
entirely emptied and cleaned out; but on examining the same 
kind of grease contained in three other pots, it was found to ex¬ 
hale a strong repulsive odour, and it reddened strongly blue paper 
tinged by turnsole. Three ounces of this grease were given to a 
vigorous well-formed dog ; an hour after, his extremities became 
violently convulsed, he cried piteously, he refused to eat, his eyes 
were suffused, pupils dilated, skin cold, and arterial pulsations 
scarcely perceptible. In this state he continued for thirty hours, 
after which he slowly recovered.

None, I believe, call in question but that there are some times 
in the year wherein one humour predomines more than another; 
for example, all agree that it is the blood which predominates in 
the Spring , in the Summer bile, in Autumn melancholy, and in 
Winter pldegm. That which is performed in the space of a year 
is renewed every six hours; which is the time wherein the whole 
circulation of the blood is perfected, as an infinite number of ex¬ 
periments have discovered. 
From midnight to six adock in the morning it is the blood that 
predominates; from si*to twelve aVlock in the day it is phlegm;
