to weigh 240 grains, and confequently if the whole acetous folution™ 
had been ufed, the refulting felenite would have weighed 288 grains: * 
Now 100 grains of felenite contain 32 of calcareous earth, there- 
fore 288 grains contain 92,16 grains, which differs inconfiderably 
from the former determination. 
Last ty, the 63 grains which eluded the action of the acetous 
acid being digefted in fpirit of falt, left a refiduum of 41,3 grains, 
which therefore were filiceous; the remainder not being precipi- 
table by the vitriolic acid was confequently argillaceous earth ; 
hence the quantities of thefe ingredients in 480 grains of the 
infoluble part of barilha were found to be) 
And in the whole infoluble part.
