I have this moment taken your letter of the 14th. inst. from the Post-office, and have step’d into the first house to write a line, and pray you to excuse me untill I return home before I can answer it properly.

The vaccine matter , which you were so good as to transmit to me 4 or 5 weeks ago, on quills & on thread, has been tried.
