From Jean-Baptiste Le Roy (unpublished)
Thursday morning

I am sending to ask, my illustrious doctor, if you shall be able to do us the honor of coming to take tea Saturday and watch a balloon or several balloons take off. Some ladies that Mme. Le Roy invited to come have asked to put off this little scientific diversion until Saturday. I have the honor of wishing you good day.

p.s. I do not know, my illustrious doctor, if this is the day which you are spending with Mme. Brillon, but you could go there afterwards. Send a little note of reply, please, as otherwise I would put it off, for the celebration would be nothing without you.
