^ijjotj Medectriy Memhre des Soctetes de Londres & de 
Bale^ (printed at Paris in 1762) I obferved a difeafe 
mentioned under the appellation of Ergot, a name 
borrowed from its fuppofed caufe, viz. vitiated rye. 
As the phasnomena of the difeafe defcribed (which 
is faid to be frequently epidemic in feveral provinces 
of France) are very fimilar to thofe of the difeafe, 
which we lately received an account from Wat- 
tifham, I took the liberty of writing a letter to M. 
TifTot, and requefled the favour of him to commu- 
nicate to me whatever had fallen under his own ob- 
fervation, with refped to the difeafe called Ergot. 
In anfwer to my letter, I have lately been favoured 
by that learned phyiician, with the inclofed collec- 
tion of curious fads and obfervations on the fubjedt 
of my inquiry : which, at his requeft, I do myfelf 
the honour to fend to the Royal Society, 
I am, 
Reverend Sir, 
Your mod obedient 
and very humble fervant, 
George Baker, 
jermyn-ftreef, Dec. 5, 1764.
