water (average for four individuals), the tails vv^hich had been 

 regenerating in their place for one month and had attained an 

 average length of about 6 mm. contained 89.08 per cent water, or 

 fully 14 per cent of water more than the old tails. From the other 

 four tables (5 to 8) it will be learned further that three months 

 after the operation, when the regenerated tails had already 

 attained an average length of about 15 mm., the average per cent 

 of water varied from 83.6 to 84.76 per cent. The old tails fall 

 within two groups, those with about 73 per cent of water (73.57- 

 73.69) and those with about 76 per cent (76.2-76.85). The 

 increase in the content of water is therefore different for the sepa- 

 rate series, but if the average is taken for all four series (5 to 8), 

 it will be found that the regenerated tails three months old con- 

 tain 7 per cent of water more than the original (amputated) tails 

 (82.08 per cent and 75.08 per cent respectively).
