the Medico-Chirurgical Transactions. The chyle was collected 
from the thoracic duct of dogs within three liours after they had 
been fed. The following were the results obtained :— 
1. Chyle from Vegetable Food.—lt appeared a short time after 
being collected, in the form of a semi-transparent, inodorous, 
colourless fluid, having a very slight milky hue, like whey diluted 
with water. It contained a coagulum, which was semi-transparent, 
and resembled the white of an egg, but had a pink hue. The 
weight of the fluid part to that of the coagulum was 100 to 48; but 
the coagulum being put into a phial by itself, a quantity of fluid 
similar to the serous portion speedily oozed out, and left only a very 
small clot. ‘This residue began to putrefy at the end of a week, 
Potash caused a slight ammoniacal smell to exhale from the fluid 
which issued from the clot; and the mineral acids, especially the 
nitric, precipitated abundance of white flakes, which were partly 
redissolved by dilution and heat. 
The serous portion had the specific gravity 1°0215 or 1:022. It 
did not putrefy in ten days, but acquired a smell similar to that of 
sour cream. Heat rendered it somewhat turbid and milky. The 
mineral acids threw down abundance of albumen: 100 parts of it 
being evaporated to dryness, left 4:8 parts of a yellow and very 
deliquescent solid residuum. Some other portions yielded more 
solid matter. ‘The greatest quantity was 9°5 per cent. 1 iil 
2. Chyle from Animal Food.—It was white and opake, like 
cream. The coagulum was white and opake, and had a more diss 
tinct pink hue. he proportion of the fluid to the coagulated por+ 
tion was 100 to 46'5. This coagulum, like the preceding, gradually 
gave out a serous fluid, till only a very small quantity of matter 
remained. This residue, somewhat similar to thick. pus, became 
putrid in three days. 
The serum, on standing, formed an opake creamy substance on 
its surface. Heat rendered it more turbid than the preceding 
serum. It contained abundance of albumen. The quantity of 
solid matter contained in it was seven per cent. 
These liquids, when distilled, gave out moisture, carbonate of 
ammonia, and a heavy fixed oil. Vegetable serum left three per 
cent. of charcoal; avd animal serum, one per cent. ‘The presence 
of iron was recognized in the residuum, and the same proportion of 
salts (about nine in the 1000 parts) that exist in animal fluids in 
general. 
IV. Chyme. 
Dr. Marcet likewise examined chyme from the stomach of a 
turkey. It was a homogeneous, brownish, opake pulp, having the 
smell which is peculiar to poultry. It was neither acid nor alkaline, 
and became putrid in 12 days. When evaporated to dryness, it left 
nearly one-fiith of its weight of solid matter. It contained albumen. 
When burnt, it left 12 parts in the 1000 of charcoal. This resi- 
duum contained iron, lime, and an alkaline muriate.
