Laffon de Ladebat, A-D. (1815) A collection of the Most Remarkable Definitions and Answers of Massieu and Clerc, Deaf and Dumb. Trans. J.H. Sievrac. (Action on Hearing Loss Library)
Laffon de Ladebat, one of the French visitors to the Braidwood's school, provides a vivid description of Clerc's meeting with the deaf children in a book written in both English and French- A collection of the Most Remarkable Definitions and Answers of Massieu and Clerc, Deaf and Dumb, (1815).
As soon as Clerc beheld this sight [of the children at dinner] his face became animanted; he was as agitated as a traveller of sensibility would be on meeting all of a sudden in distant regions, a colony of his own countrymen … Clerc approached them. He made signs and they answered him by signs. The unexpected communication cause a most delicious sensation in them and for us was a scene of expression and sensibility that gave us the most heart-felt satisfaction.
