on the Spleen. 137 
two from the large vein of the colon, and two from the infe- 
rior vena cava in the lower part of the loins. 
The spleen had the same appearance as in the last experi- 
ment. 
The stomach contained nearly a pint of moderately solid 
contents, in which the rhubarb was very evident. The small 
intestines were nearly empty ; but the caecum and beginning 
of the colon contained several quarts of liquid, strongly im- 
pregnated with rhubarb. 
The absorbent glands and vessels had the same appearance 
as in the former experiment. 
The urine when tested was found impregnated with rhu- 
barb. 
The portions of serum of the blood taken from these dif- 
ferent veins, when tested by the alkali, appeared to be very 
much alike ; at least that from the splenic vein was not more 
tinged than the others. 
Exp. 6. Having been informed by Mr. Sewell, that spi- 
rituous liquors given in large quantities to horses, produce 
inflammation of the brain, and sometimes death, and this in- 
formation having been in some measure confirmed by an ass 
in a weakly state, that had taken half a pint of the spirituous 
tincture of rhubarb in the evening, dying in the night, I thought 
it right to make a comparative experiment with the infusion 
of rhubarb, to determine whether the result would be the 
same as with the tincture. 
February 9, 1808. An ass had a pint of infusion of rhubarb 
given to it in the evening ; the same dose was repeated at six 
o’clock in the morning of the 10th ; and again at nine o’clock, 
and at twelve. At two o’clock the animal was pithed, and two
