420 ANALYSIS OF THE BLOOD OF THE VENA PORTA, ETC. 
“Moreover, MM. Sandras and Bouchardat themselves had already proved 
the existence of these grannies, which they designated under the name of 
globulines, but to which they appear to assign no importance, because they 
could not play any part in their theory of saccharification. 
“ The preceding facts show, in the most evident manner, the explanations 
above given, relative to the disaggregation of fecula by the gastric juice, 
although the stomach may be the part of the digestive tube which presents 
the fewest granules which are disaggregated and capable of assuming a 
yellow colour with iodine. The same thing, therefore, happens to fecula 
which occurs to all other aliments, which are separated into portions in the 
course of digestion, and pass into the intestine in proportion as they have 
undergone in the stomach a sufficient attenuation. 
“There is yet one other remark which we must not omit. It is that the 
nitrogenous matter uniting the granules of which fecula is formed, has 
this in common with many alimentary matters, especially with the substance 
of the bones, that, to be attacked by the gastric juice, it is necessary that 
the latter should possess all its power. Now we know that, for some 
reason hitherto unknown, this fluid loses a portion of its specific virtue 
when removed from the stomach. Moreover, we know that its powers are 
only developed at a temperature of 40° C. (104° E.) These two peculiari- 
ties explain why it is impossible to disaggregate fecula in what are called 
artificial digestions, and likewise while fecula passes unaltered through 
the digestive tube of cold-blooded animals, as I have proved by numerous 
experiments. 
“ To sum up, from the preceding facts and considerations, it results that, 
according to the above-mentioned principle, the digestion of fecula is 
affected in the stomach of warm-blooded animals in the same manner as 
that of other aliments, and consists in the disaggregation of the elementary 
granules constituting it : so that the latter, whose dimensions do not 
exceed those of the chymous molecules furnished either by fatty matters 
or proteic substances, are found to be in a state of division sufficient 
to penetrate with them into the organism by means of the chyliferous 
system.”

COMPARATIVE ANALYSIS OE THE BLOOD OE THE VENA 
PORTA AND HEPATIC VEINS, &c. 
By M. C. G. Lehmann. 
The results of the following analyses were obtained with 
dogs and horses submitted to various diets (care was always 
taken to place ligatures in a suitable manner on the vessels, 
in order to obtain without admixture the bloods to be exa- 
mined chemically). 
I shall not dwell upon the analytical processes which I 
followed; these are described in my c Lehrbuch der Physiologische 
Chemie 5 (1850, Leipzig). I shall only say that all the quanti- 
tative determinations of sugar were obtained by means of the
