lower temperature retarded bacterial decomposition. Worms Nos. 

 8-13, and 16-22, inclusive, did not show clitella. Many individ-

The results of these experiments, with twenty-two individuals,

 tained in their bodies, was given up without loss of vitality; (2) 

 lower temperatures were more favorable to the recovery of exsic-
