Experiment 5. 6th of May, 1809. 
Two small platina cups, connected by a large quantity of 
cotton well washed, and each containing one ounce of serum, 
were rendered positive and negative, by thirty double three 
inch plates very weakly charged. The process was continued 
during twenty-four hours. This power had not been sufficient 
to produce coagulation at the negative pole. On examining 
the fluid in the negative cup, it was found to consist principally 
of an alkaline solution of albumen. 
The fluid in the positive cup was rather turbid, it reddened 
litmus, and was slightly acid to- the taste. On standing, it 
deposited a few flakes of albumen. When evaporated, it af- 
forded saline matter, with excess of add, (super salts.) 
By these experiments it is ascertained, that a low negative 
power of electricity separates from the serum of the blood an 
alkaline solution of albumen ; that a low positive power sepa- 
rates albumen with acid, and the salts of the blood. Thai with 
one degree of power, albumen is- separated in a solid form, 
with a less degree, it is separated in a fluid form. 
From these facts, the following, queries are proposed. 
1st. That such decomposition of the blood by electricity, 
may be as near an approach to secretion, as could be expected 
to be produced by the artificial means at present in our 
power. 
sd. That a weaker power of electricity, than any that can 
be readily kept up by art, may be capable of separating from
