Yes, this remedy will make you hear -- if what you want to hear is the sound of hot chicken fat quishing around in your head.

How to Picnic, 1876

I seem to have forgotten something. The potato salad?
Édouard Manet, Le Déjeuner sur l'herbe, 1862-3

"Invitations for a picnic should be sent out about ten days before the time named, or at least long enough to fill up any vacancies caused by refusals. The food and delicacies of all kinds provided should be abundant, and, of course, cold. It should be sent on to the spot fixed on under the care of the servants. Take care to have carriages which will close in case of rain amongst your conveyances. The above instructions relate to a picnic given by one person to her friends. The ordinary picnic is an arrangement between more or fewer persons to bring provisions, &c., and share expenses. In this case the ladies supply the eatables, the gentlemen the wine."
