Temperature was ascertained by means of a mercury therioometer 

 or, in deeper niches, by a Strelmikov thermocouple. Humidity was 

 determined by Buxton's dew point device. Observations were made 

 twice a month every two hovirs of the day from 2L, July to 6 Sep- 

 tember . 



On northern hill slopes, air temperature in soil cracks 

 fluctuated from 22°G . to 28°C . in one day but in a Meriones bur- 

 row on the same slope only from 23.5°C. to 26.0°C. In the morning, 

 RH was maximum (54^), at 1300 minimum (40^). In these places, 

 hatching was most rapid. 



In tubes on the soil siu"face among herbage, on southern hill 

 slopes, in which females died, air temperature before sunrise was 

 19.0°G. but at midday ^5.3°C. RH varied from 2% at 1100 to 60^ 

 at 2300. 



In certain soil cracks where RH fell to extreme midday lows, 

 (10 or 15$S), eggs perished. 



Tubes among grass roots in raountain steppes and in irrigated 

 plots, in which larvae hatched more slowly than in those in soil 

 cracks, experienced daily temperatures ranging from 13.5°C. to 

 29.0°C. in the former biotope and from U.5°C. to 31.5°C. in the 

 latter. RH in the former varied from 3-^ to 100^, in the latter 

 from 32% to 3%. A number of other data are provided, but these 

 are the high points and indicate the overall planning, methods, 

 and resvilts of the experiment. /"Translated copies of the entire
