acid until the dry substance had attained a constant weight 

 (19.1 mgrm.); by subtracting the weight of this residue from the 

 weight of the live animals, it was found that thej^ contained on 

 the average 1.345 mgrm. of water. Expressing the same thing in 

 different terms, these worms contained 73.8 per cent water at 

 the time of the operation. Another sample of 40 worms, also 

 taken at random, was examined two days after the operation, i.e., 

 July 9, and the weight was found to be 67 mgrms., or on an aver-

age 1.675 mgrm. But while the weight of the live worms had 

 decreased in comparison with that of the control group, the rela- 

 tive quantity of water in the body had increased, as is shown by 

 the higher percentage of water — 74.63. Five days after the per- 

 formance of the operation, July 12, a similar group of worms, 

 weighing on an average 1.630 mgrm., was dessicated, and the 

 average water content was found to be 76.69 per cent, or nearly 

 3 per cent above that of the control. July 15, or eight days after 

 the operation, the per cent of water had increased to 77.08; and 

 five days later still, July 20, thirteen days after operation, the 

 maximum water content (79.42 per cent) was reached. This 

 represents an increase of 5.6. per cent over the control. The per 

 cent of dry substance had meanwhile dropped from 26.20 to a 

 minimum of 20.58.
