He really thought the universe was composed of shells and the remains of shells, and that the whole earth was only the sand of these in different stratae.

His attention thus constantly engaged with his singular discoveries, his imagination became so heated with the ideas they gave him, that, in his head, they would soon have been converted into a system, that is into folly, if, happily for his reason, but unfortunately for his friends, to whom he was dear, and to whom his house was an agreeable asylum, a most cruel and extraordinary disease had not put an end to his existence.

A constantly increasing tumor in his stomach prevented him from eating, long before the cause of it was discovered, and, after several years of suffering, absolutely occasioned him to die of hunger.

I can never, without the greatest affliction of mind, call to my recollection the last moments of this worthy man, who still received with so much pleasure, Leneips and myself, the only friends whom the sight of his sufferings did not separate from him until his last hour, when he was reduced to devouring with his eyes the repasts he had placed before us, scarcely having the power of swallowing a few drops of weak tea, which came up again a moment afterwards.

But before these days of sorrow, how many have I passed at his house, with the chosen friends he had made himself! At the head of the list I place the Abbe Prevot, a very amiable man, and very sincere, whose heart vivified his writings, worthy of immortality, and who, neither in his disposition nor in society, had the least of the melancholy coloring he gave to his works.
