APPENDIX 



In the following pages will be found, in tabular form, the detailed experi- 

 mental results. Most of them have been presented in graphic form in the charts. 



The values tabulated are the Briggsian logarithms of the numbers of survivors 

 per cubic centimeter of water or buffer solution. Observations of the pH of the 

 suspending fluid are noted wherever made.
