forming a straw-coloured solution, which is rendered turbid 
when the alkalies are added to exact saturation, but no preci- 
pitate falls, nor can any be collected by filtration. When 
either acid or alkali are in excess in this solution, it remains 
transparent. 
8. Acetic acid dissolves a small portion of the coagulum of 
chyle, when boiled upon it for some hours. As the solution 
cools, it deposits white flakes, which have the properties of 
coagulated albumen. 
9 The action of oxalic acid is nearly similar to that of the 
acetic, but neither citric, nor tartaric acid, exert any action upon 
this coagulum. 
10. The destructive distillation of this substance affords 
water slightly impregnated with carbonate of ammonia, a 
small quantity of thin fetid oil and carbonic acid and carbu- 
retted hydrogen gas. 
The coal which remains in the retort is of difficult incinera- 
tion ; it contains a considerable portion of muriat of soda and 
of phosphat of lime, and yields very slight traces of iron. 
C. i. The serous part of the chyle becomes slightly turbid 
when heated, and deposits flakes of albumen. 
2. If after the separation of this substance the fluid be eva- 
porated to half its original bulk, at a temperature not exceed- 
ing 200° Fahrenheit ; small crystals separate on cooling, 
W'hich, as far as I have been able to ascertain, bear a strong 
resemblance to sugar of milk : they require for solution about 
four parts of boiling water, and from sixteen to twenty parts 
of water of the temperature of 6 o°. They are sparingly so- 
luble in boiling alcohol, but again deposited as the solution 
cools. At common temperatures alcohol exe;ts no action upon
