The total amoimt of carbonate of soda, calculated from the chloride of sodium, sulphate of soda, and including that already present in the form of 
carbomt^.^'s^?^^ the freshly-gathered plant would, calculating from the above data, furnish about 212 lbs. of common commercial crystallized carbonate of 
soda. 
By simple exposure in a room the freshly-gathered plant lost 75*6 per cent, of its water. 
The percentage of chloride of sodium in seawater averages 2*71.

(6.) Tlie percentage of water in the leaves of thow? siiecivs or trees the names of which are embraced by the bracket is shgbtly augmented by 
loss by oaseutial <*il The greatest error resulting from this cause would occur in the percentage of water in the Icavee n! Eucalyptus 
gb'btihis (which afford a larger percentage ol essential oil than any of the uiUer leaves hero cmplvyed), and could here amount to 0*72 
per cent.
