REST. 



It is sometimes suggested that a period of inactivity will 

 stimulate weak organisms. Therefore both races were kept at 

 3 C. to 7 C. for about three weeks in a rich food culture and then 

 were placed at room temperature but failed to show any increase 

 in the rate of reproduction. Some close-fertilized eggs of race B 

 were kept in water at room temperature for about a year and then 

 allowed to hatch. Table II. shows that this long period of rest 

 produced no stimulation upon the race. 



TABLE II. 



Close-fertilized eggs of race A were dried and kept at room 

 temperature for about eight months. Table III. shows the nega- 

 tive results obtained. 



TEMPERATURE. 



Of course, temperature has much to do with the state of 

 activity of the particles of matter. In order to further test the
