5. In the survival time experiments, heightened sensibility 

 was sometimes followed by over-stimulation and always by 

 depression and apparent fatigue (pp. 109-10). 



6. There is a rough agreement between survival time and kind 

 of integument but no agreement between survival time and 

 habitat when a number of different members of a community 

 are taken together (p. 106). 



7. The rate of evaporation is the best index of the combined 

 action of wind, temperature, isolation, and dryness of air. 



8. Temperature is probably no more significant than moisture, 

 isolation, or wind (p. 112).

VII. ACKNOWLEDGMENTS AND BIBLIOGRAPHY. 



The writer is indebted to Professors A. P. Mathews and Carl- 

 son and Dr. Tashero for suggestions in connection with the 

 preparation of the manuscript and to Mr. E. O. Deere for 

 reading the proof of the part which he did not help prepare. It 

 should be stated here also that the bibliography does not pur- 

 port to be complete but it is hoped that it will serve as a key to 

 the literature on the subject. References which have not been 

 consulted are starred and are included because their importance 

 is emphasized by other authors.
