them. The taste of their aqueous solution is extremely sweet 
By nitric acid they are converted into a white powder of very 
small solubility, and having the properties of saccholactic acid, 
as described by Scheele.* 
The form of the crystals I could not accurately ascertain 
even with the help of considerable magnifiers. In one in- 
stance they appeared oblique six-sided prisms, but their ter- 
minations were indistinct. 
Some of the crystals heated upon a piece of platina in the.

Analysis of Lymph. 
The fluid found in the thoracic duct of animals that have- 
been kept for twenty-four hours without food, is perfectly 
transparent and colourless, and seems to differ in no respect 
from that which is contained in the lymphatic vessels. It may 
therefore be regarded as pure lymph. 
It has the following properties.-!* 
1 . It is miscible in every proportion with water* 
* Chemical Essays, No. XVII. 
+ The term lymph has been applied indiscriminately to the tears, to the matter 
of encysted dropsy, and to some other animal fluids. Vide Ai kin’s Dictionary of 
Chemistry and Mineralogy, Art. Lymph.
