 milk is reddish. (4) Avoid fungi in which the cap, or pileus, is thin in propor- 

 tion to the gills, and in which the gills are nearly all of ecjual length, especially 

 if the pileus is bright colored. (5) Avoid all tube-bearing fungi in which the 

 flesh changes color when cut or liroken, or where the mouths of the tubes are 

 reddish, and in ca.se of other tube-bearing fungi experiment with caution. ((>) 

 Fungi which have a sort of spider web or flocculent ring around the upper j^art 

 of the stalk should in general be avoided."

mic center of ciliary motion. He 



carries on his studies to determine whether it is situated in the nucleus, proto- 

 plasm or in some part of the cilium itself. In view of the tendency of modern 

 work to look on the centrosome as the dynamic center, previous workers have 

 suggested the possible homology of the basal bodies on the cilia with that part of 

 the cell, on purely theoretical grounds. 



The author took the intestinal epithelium of Anodonta for his studies, and after 

 much experimenting found the following the best method of treatment : cutting 

 through the foot muscles of the animal when immersed in normal, salt solution 

 freed in part the intestine. A piece of this was then put on a slide and cut into 

 fragments with a sharp knife ; the cutting being done in all possible planes. 

 In spite of the apparent roughness of the process it gave very good results, cells 

 being quickly and thoroughly isolated and cut in many ways.
