Protozoan Studies 28 1 



APPENDIX 



Dr. Jenning's paper entitled "Heredity, Variation and Evolu- 

 tion in Protozoa. I" (this journal, vol. v) appeared after this 

 paper had been sent to press. I w^ould emphasize a probable 

 difference betw^een the process of heredity in Protozoa and in 

 Metazoa other than the difference in complexity. In Protozoa 

 the "germ-plasm," w^hether it be all or part of the individual, 

 is probably equally as accessible to the environment as the 

 "soma." I use the w^ords "germ plasm" and "soma" for 

 brevity.
