The increase, therefore, of the plant every day, amounts to 657 grs., of which 546 are 
water and 111 dry matter.

Inorganic matter assimilated August 11 - 195-54 
Inorganic matter assimilated July 29 - - 87*06 
Increase from July 29 to August 11 - - 108-48 
Increase of inorganic matter about 10 grs. per day. 
It will be observed that the increase in weight for two periods, from July 18 to July 29, 
and from July 29 to August 11, is virtually equal, only three additional grains remaining 
in favor of the last period (See Meteorological Observations and Tables at the end of the 
volume). The perfect solution of the inorganic matter is maintained by the large amount 
of water always circulating in the plant : thus, in August 11, there was 13255 grs. of 
water, and only 165j grs. of mineral matter.
