Peas, during their germination, pushed to this extreme term, 

 therefore, suffered a loss of about 52 per cent., the loss being refer- 

 able to each of their constituent elements, which are summed up in 

 carbon, water, and ammonia. 



7.719 of oxygen taking 0.972 of hydrogen to form water; 

 0.339 of azote requiring 0.077 of hydrogen to form ammonia ; 



1.049 which represents as nearly as possible the quantity of 

 hydrogen eliminated. 



In this experiment, therefore, we see that a seed weighing 3.453 

 grs. troy, suffered a daily loss of about 0.077 of a grain troy of 

 carbon. 



CONTINUED GERMINATION OF WHEAT. 



On the 5th of IMay, 46 corns or grains of wheat, supposed to be 

 quite dry, and weighing 1.665 grm. or 25.704 grs. troy, were set to 

 germinate in the dark. 



On the 25th of June, the germinated wheat, when dried, weighed 

 0.713 grm. or 11.007 grs. troy.
