Upon placing it in the Voltaic circuit my suspicions were 
justified, by the rapid coagulation which took place in contact 
with the negative wire. I therefore made some other experi- 
ments in order to corroborate this result. 
One fluid ounce of pure serum was dissolved in three of 
distilled water : the conductors from a battery of thirty pairs 
of four inch plates were immersed in this solution at a distance 
of two inches from each other; the electrization was conti- 
nued during three hours and a half, the solid albumen being 
occasionally removed ; at the end of that period, no further 
coagulation took place, and a mere decomposition of the water 
was going on. 
Having ascertained in previous researches, that gelatine is 
not altered during the electrical decomposition of its solution 
carried on as just described, my object in this experiment 
was, to ascertain whether any gelatine remained after the 
complete separation of the albumen had been effected. I ac- 
cordingly examined the water from which the coagulated 
albumen had been removed, and found that it was not altered 
by infusion of galls, nor did it afford any gelatine when eva- 
porated to dryness. 
Two fluid ounces of dilute muriatic acid were added to one 
of serum. The mixture immediately assumed a gelatinous 
appearance ; it was heated, and a more perfect coagulation of 
the albumen took place ; the liquid part was separated by a 
filter. No effect was produced upon it by Voltaic electricity, 
nor did infusion of gails occasion any precipitation. 
• I repeated the first experiment with the addition of twenty 
drops of a solution of isinglass to the serum. The liquid which 
now separated, after the albumen had been entirely coagulated
