n the Ist of June, Sanson announced to the Acad- 
emy * the discovery of glycogenic matter in the spleen, the 
lungs, and the kidneys, as well as in venous, arterial, and por- 
tal bloo 
(27.) At the next session, Fiavirr} communicated some 
experiments to prove that washing the liver by Bernard’s 
method for forty minutes did not deprive it of sugar. He 
therefore pulped a liver and washed it until free from sugar; 
none re-appeared after 24 hours standing. He then washed a 
liver by Bernard’s method for 11 hours, and on dividing it into 
two parts, found that one at once reduced ‘123 grams cuprous 
oxyd, while after 24 hours, the other half only produced -102 
grams. In a third experiment a horse’s liver, proved to con- 
tain sugar, was washed through the portal vein for 2! hours;

matter into xyloidin, were presented to the Academy June 29,t 
by Eve. Petovuze. One gra m of the pure substance was mixe 
with concentrated nitric acid ; ; in a few moments it dissolved, 
and the whole was then poured into witcher! to precipitate the 
xyloidin. This, after drying, weighed 1-3 grams, the theoreti- 
eal quantity. It was very combustible, taking fire at 180° C.
