commenced 3 years ago with my own family( and then sent them into f. p. hospital )
Since that period I have regularly published every
important information as I received it from England, and
kept not back any useful discovery made in my
own practice. This I continued unremittingly untill
the conviction all doubts were removed by the public
expt. of the Board of Health made in consequence
of my memorial to them. Direcly after this I
published a volume containing all I know both
of the theory & practice of vaccination. During this anx-
ious & arduous business I was animated with more
powerful motives than private emolument. But
feeling that this business was attended with expence,
and foreseeing that the sacrifice of my private practice
to it, I conceived it necessary to devise some plan
to bear me out in the expences attendant on the
introduction of this new inoculation into the U.S.
A plan was adopted, but not without advice of some
of the most leading medical & clerical characters
in this & several other states. It was in substance this –
to exact a certain tax from such practitioners, who
ignorant of the business, applied for matter & in-
structions for their own emolument exclusively.
