Dr. Marat has the honor of giving his compliments to Monsieur Doctor Franklin, and informing him that he is gathering, on Tuesday the 24th of this month, Messieurs the committee members, who will come at nine-thirty in the morning, and have dinner at his house.

M. Marat would be very pleased if M. Franklin wished to add to the number of this good company. He will be flattered to show him some new interesting and curious experiments.
