entirely without action if it be either acid or alkaline. The — 
trace of sugar (0-047 to 0-073 per cent) found in right ven- — 
tricular blood, is caused, as Pavy supposes, by the escape of a — 
small amount of hepatine from the liver; since any disturb- — 
ance in the circulation, either by congestion or otherwise, — 
causes this amount of sugar to increase. Moreover, on arti- — 
ficially introducing hepatine into the blood, this fluid becomes 
saccharine ; and if “egos goed be injected, strongly marked dia- ~

(43.) On the Lith of Tay, 1859, Bernard presented to the — 
Academy * a letter from C. Scamp of Dorpat communicating — 
the results of his examination of the portal and hepatic blood 
of three dogs, two of which were digesting meat, the other had | 
fasted for two hours. The portal blood contained no sugar 
in either case ; the hepatic nearly one per cent of the dry resi- — 
due, for the first two dogs, and about } per cent for the third. _ 
Or more exactly, 0°93 and 0-99 for the dogs in digestion, 0° e t 
per cent for the fasting animal; thus confirming Lehmann 
results, 
DE Luca give the results of a research to determine the nature 
of the licens yielded by the transformation of Bernard’s gly- 
cogenic matter. It has never been shown whether this sugar _ 
is identical with any of the known varieties, such as grape- 
sugar, malt-sugar, levulose, lactic glucose, etc., or whether if. _
