ANABIOSIS OF THE EARTHWORM

end the worms were placed after the exsiccation in test-tubes 

 upon the ice of an ice-house, where the temperature was about 

 + 1°C. 

 The results of the drying are given in table 7.

Worms nos. 1, 4 and 5 were placed after drying in test-tubes 

 and carried to the ice-house. Worms nos. 3 and 6 were placed 

 immediately on moistened filter-paper. No. 2 was left in the 

 laboratory at the normal temperature of about 20°C. (in day- 

 time) . 



The worms placed upon the ice (nos. 1, 4, and 5) were kept there 

 for fifty-one hours (till 13 VIII 16h 20') and seemed then to be 

 completely normal without signs of infection. Nevertheless, the 

 revivification was unsuccessful. Placed on moistened filter-paper 

 13 Vm 16h 30' they displayed at 17h weak movements in the 

 proximal end and in the tail. 



Worm no. 1 at 18h 45' exhibited energetic contractions of the 

 proximal end, but its tail moved weakly and the middle part of 

 its body was motionless. Worm no. 4 was dead. No. 5 dis- 

 played energetic contractions in the tail and in the head, but the 

 middle part of the body with clitellum had died. 



Next day (14 VIII lOh 30') the proximal end of worm no. 1 

 and its tail contracted very energetically, but the middle part of 

 the body died. Clitellum showed blood effusion and the filter- 

 paper beneath was red. The proximal end and the middle part 

 of the body of worm no. 5 died, but its tail contracted. In the 

 evening 14 VIII both worms were definitely dead.
