hairlike pseudopodia had their ends bent and somewhat thickened. 

 11 a. m. The hairlike pseudopodia are nearly all gone, and at 11. 2 

 a. in. they have ceased to exist, and the animal is evidently in 

 disintegration. 11. 5 a. m. The animal is in dissolution, and the 

 central capsule is escaping. 11. 27 a. m. Shockingly disintegrated. 

 1.30 p.m. Contents of capsule scattered in fluid. At 11.18a.m. 

 it is noted, that the addition of one drop of the further diluted 

 ferment-solution to a drop of water containing Actinosphaerium 

 causes immediate shrinking and shrivelling-up of the fine delicate 

 pseudopodia. 



XVII. Stentor coeruleus. Temperature 14 C. The usual stock- 

 dilution of 10 c. c. of the ferments T. & A. was made up. Of this 

 one cubic centimetre was diluted with four cubic centimetres of 

 clean fresh rain-water. Five watch-glasses, each containing a number 

 of Stentor, were labelled A., B., C., D. and E. In the order given 

 these contained rain-water as follows: 18, 16, 14, 12, and 10 drops. 

 The bulk of each was made up to 20 drops by additions of the 

 further dilution of the ferments, or 2, 4, 6, 8, and 10 drops of the 

 solution thus diluted. It was calculated out, that at the most the 

 glasses would contain the following numbers of tryptic units 

 (Roberts): 3, 6, 9, 12, and 15. The experiment began at 11. 30 a. m. 



11. 40 a. m. Stentor in E and D mostly at rest. In C some in 

 movement. 11. 41 In B some moving fairly quickly. In A the 

 specimens of Stentor are moving as though nothing had happened. 

 11.42 The animals in D and E appear to be in disintegration. The 

 cilia are not obvious. 11.45 The animals in A and B are still in 

 movement. Most of those in D and E are dead. 11. 49 In E 

 disintegration is going on rapidly, but in D a water flea, Daphnia 

 pulex, is actively moving. This was seen later on, alive and active, 

 27 minutes after the experiment started. Afterwards it was lost 

 sight of. The animals of Stentor in the same watch-glass were 

 killed in ten minutes or less. 11. 54 In B many Stentor in dis- 

 integration, but some still in movement. Stentor in C in disintegra- 

 tion, no ciliary motion. 12 noon. In A and B still some movement. 



12. 3 Movements in B appear to be ceasing, but not in A. 12. 4 

 p. m. Animals in E greatly disintegrated, many Algae freed. 12. 18 

 Heaps of freed Algae in D and E. 12. 20 In A still some ciliation, 

 but in many the cilia are working feebly. 12. 25 The animals in 

 B are now much disintegrated. 12. 32 Slow ciliation in A and all 

 the animals are crowded together. 2 p. m. In A still the same 

 condition of affairs, but only one animal moving cilia. At 7 p. m.. 

 when the experiment was closed, there were still some animals of 

 Stentor alive in A, but in the four remaining watch-glasses all the 

 specimens of Stentor were dead and in disintegration.
