Ulf lasl ;j days, which may explain the small quantities of the CO., produced during 

 tlie latter period. The second and the third portions received doses of ether the 

 first two days: 



The first day and night the elher produced a small retardation of the respi- 

 ratory process and the next day a small acceleration, a phenomenon which may 

 possibly be explained to the fall of temperature, hi the time after the exposure to 

 ether a large retardation of the CO, -production was noted. The 10th of April the 

 seeds of the three sets were in the same stage as regards their germination, but at 

 the end of the experiment the seeds of the first portion predominated. 



VI. 3 sets of seeds were soaked and put aside for 5 days in order to germi- 

 nate (Febr. 24th— March 1st). In the day the temp, was c. 18° C. The second and 

 third portions were allowed to stand each with a small dose of ether for the first 

 25 hours; during the last 4 days they received no ether: 



During the narcosis and in the time directly after this exposure the respira- 

 tory process was somewhat retarded, but afterwards the CO^-production was again 

 accelerated especially as regards the portion which had been exposed to the smallest 

 dose of ether.
