WHAT COMES FROM WHAT* 



This pamphlet in a series of 41 diagrams modestly attempts 

 to show the relationships and development of all forms of life. 

 The author claims simply " to set forth the opinions of specialists 

 as they have been gathered a little here and a little there." 

 Diagram i, beginning with Hydrogenomonas, shows by arrows 

 the derivation of the nitrobacteria and from them of the flagel- 

 lates which in turn give rise to the various groups of algae and 

 protozoans. Diagram 2 completes the algae and leads to the 

 mosses in one direction and to the sponges and coelenterates in 

 another. There follow ten diagrams tracing the plant groups 

 up to the Asterales, where fifty of the genera are worked out. 

 The remaining diagrams trace the development of animals up 

 to man. 



The tables are rather difficult to use as there is but little to 

 show how they are connected to each other. With their maze 

 of lines and scientific names the diagrams can be of little value to 

 any except scientists. The author realizing this has given below 

 each a simple description, the character of which can best be 

 shown by a few quotations: "When the naked seeds of the Gym- 

 nosperms clothed themselves with skins or otherwise they became 

 Angiosperms." "It is believed that the fins of fishes, paddling 

 on muddy shores, became feet." — G.T.H. 



PROCEEDINGS OF THE CLUB

Variation in Nephrolepis, considered as a process, may at 

 present be judged only by its products, the different species 

 and varieties. According to the multiplicity of these, modi-
