From the Abbé Jacob Hemmer
AL: American Philosophical Society
<Mannheim, September 24, 1778, in Latin: Wishing to give
you a token of its esteem, the Palatine Academy of Sciences
has entrusted me with the pleasant task of sending you its
Transactions. I rejoice in this chance to thank you again for the
kindness you showed me and my friend Delor in Paris recently.
Of the five volumes I am supposed to send you, the first
two are made up of a mixture of history and natural science;
the others deal with separate topics. The fourth, which I shall
ship as soon as it gets off the press, is all physics. It contains
four of my essays—one on lightning rods in the Palatinate,
one on memorable strokes of lightning, one on an electrical
cure for paralysis that I performed, and one on the perpetual
“electrophore” which I built here.
I will send you soon the by-laws of our own German Society,
in the hopes that it will become the sister of yours.>
