exposed lo ether [with I'egard to a detailed indication of tlie experiment cfr. p. 28, 

 where the other results of the experiment are stated]. The temp, varied between 

 13° and 15° as long as the experiment lasted. 



The following is demonstrated by above mentioned experiments: 

 The destruction of proteids, which takes normally place during the germina- 

 tion together with a simultaneous formation of amides, is retarded' during the 

 narcosis in proportion to the size of the dose used. That very small doses used 

 for an exposure of a certain duration may cause an acceleration of the above 

 named process will be shown (cfr. p. 30, 33). During the after-effect of the ether- 

 narcosis a considerable acceleration of the katabolismes takes place if small doses 

 are used (cfr. V, VI), while large doses have here too retarded the formation of 

 amides (cfr. VII, 2). The increase of amides, shown in III, 3 is doubtlessly owing 

 to a secondary process, the katabolismes being a consequence of the death of the 

 plants, a phenomenon also shown by the analyses of the amounts of sugars (cfr. 

 p. 23). Accordingly the plants in that portion did not germinate. Also in VII, 3 

 a similar increase of the amides is noted, a circumstance which indicates that the 

 seeds were injured by etherization. This hypothesis is gainsaid by the fact that 

 the seeds began to germinate; nor do the results, obtained by the sugar-analyses, 

 indicate that the etherization caused any toxic effect.
