CHEMISTRY.
[CONVERSATION XIII.]
ON THE ATTRACTION OF COMPOSITION.
MRS. B.
Having completed our examination of the simple or elementary bodies, we are now to proceed to those of a compound nature; but before we enter on this extensive subject, it will be necessary to make you acquainted with the principal laws by which chemical combinations are governed.
You recollect, I hope, what we formerly said of the nature of the attraction of composition, or chemical attraction, or affinity, as it is also called?
EMILY.
