 lular animals up to 1929, see the present author's "Genetics of the 

 Protozoa," Bibliographia Genetica, 1929, Vol. 5, pp. 105-330. In this 

 work will be found an extensive bibliography. References there given

 tions briefly referred to herein, reference may be made to the above

 be made to the original papers.
