same dose has been used. This must surely be subscribed lo the circumslance 

 that the temperature in this experiment was much higher. 



III. 3 "common-legume" portions were soaked and put aside for 3 days for 

 germination (Apr. 17th— 20th). The temp, in the day was 16-18°, 2nd and 3rd 

 portions received doses of ether for 2 days; the third day they received no ether.

Also in this experiment the etlier has produced a retardation of the C02-pro- 

 duction both during the narcosis and during the after-effect. The seeds in 1. ger- 

 minated; no germination in 2. and 3. 



IV. 3 "common-legume" portions were soaked and put aside for 4 days to 

 germinate. During the first day the temp, was 10 — 12° C, as no fire was made in 

 the laboratory; during the last days the temp, was 16—18°, 2nd and 3rd portions 

 received ether for 3 days; the last day they were without ether.

During the beginning of the exposure the ether caused an acceleration of the 

 CO;, -production but after two days this process was so much retarded that the 

 production of CO., grew less than normal ; a considerable retardation of the CO,- 

 production is especially found in the period after the exposure to ether. The seeds 

 were germinated in 1., not in the other sets. 



V. 3 "common-legume" sets were soaked and put aside for 4 days for ger- 

 mination (Apr. 8th — 12th). The temp, was 16° C the first day, but only 8° to 10°
