buds had yet appeared upon the plants. Apple-trees were be- 
ginning to blossom in the vicinity at the time. The following 
results were obtained on analysis : —

Il. Mitx-Weep (Asclepias Cornuti). Sprouts and shoots from 
four to twelve inches long were cut off just below the surface of 
the ground on the 23d and 28th of May, 1877, at times when 
apple-trees were in blossom and going out of blossom. Although 
the shoots dried with extreme slowness, none of them blackened in 
drying excepting a single stalk, which was thrown away. ‘The 
dry stalks and the leaves attached to them were all ground to 
powder together for the analysis. The following results were 
obtained : — 
Milk-Weed Shoots. Air-dried. Dried at 110° C.
