Series 564, A 1,B 1. Worms 8 to 9 mm. in length, all from the 

 same stock. Lot A 1, ten worms at 20° to 21°C. Lot B 1, ten 

 worms at 10° to 11°C. Only hom-ly observations recorded. 

 Table 8. 



Observations were not carried further on this series. Table 

 8 shows two gaps in the observations, one during the night, when 

 no observations were made, the other after the death of B 1 

 where the records are omitted from the table as not essential. 

 These gaps do not interfere in any way with the definiteness of 

 the results. 



Here the worms show earlier and more rapid disintegration 

 at the lower temperature: apparently some other factor than the 

 rate of reaction is the chief factor here. Here again the tempera- 

 ture coefficient of distribution is certainly not sufficient to account 

 for the marked difference between the two lots. As a matter of
