HEADS OF FAMILIES cannot be too strongly ad-
monished against the common but pernicious prac-
tice of administering to their Children in any of their
„little ailments those drastic powders, all of which contain
more or less of Calomel, which they are so constantly in
the habit of procuring from their apothecary or chemist ;
for although the convenience of their minute bulk and
absence of nauseating taste is great, yet the frequent re-
petition of such medicines produces a softening of the
bones and premature decay of the teeth most prejudicial
to the constitution during the whole period of life. Of
late years there have been made great improvements in
Vegetable Chemistry, by which the active principles of
many simple and innocent medicines have been separated
from their inert and nauseating parts. The greatest boon
has been conferred upon mankind, and more especially
upon the rising generation, by separating the active prin-
ciple of that universally esteemed purgative, Senna, by
Mr. John Freeman, a practical chemist, living in the
Blackfriars-road, who has removed all its nauseating and
griping properties, and rendered it so peculiarly pleasant
to the taste, that children will take it with a positive re-
