Morchella esculenta (Common morel). Two lots of this species were ob- 

 tained from Stockbridge, Mass, (a) The specimens were of full size. Thir- 

 teen morels weighed 195 grams, or an average of 15 grams each. (6) Small, 

 young morels. An analysis gave :

In the same species Pizzi* has found 0.575 per cent nitrogen, a figure in 

 close agreement with the above results when calculated upon the fresh mate- 

 rial, viz. (a) 0.48 per cent N ; (b) 0.47 per cent N.
