Of these recollections I shall relate one example, which may give some idea of their force and precision. The first day we went to sleep at Charmettes, the way being up-hill, and Madam de Warrens rather heavy, she was carried in a chair, while I followed on foot. Fearing the chairmen would be fatigued, she got out about half-way, designing to walk the rest of it. As we passed along, she saw something blue in the hedge, and said, "There's some periwinkle in flower yet!" I had never seen any before, nor did I stop to examine this: my sight is too short to distinguish plants on the ground, and I only cast a look at this as I passed: an interval of near thirty years had elapsed before I saw any more periwinkle, at least before I observed it, when being at Cressier in 1764, with my friend, M. du Peyrou, we went up a small mountain, on the summit of which there is a level spot, called, with reason, 'Belle—vue', I was then beginning to herbalize;—walking and looking among the bushes, I exclaimed with rapture, "Ah, there's some periwinkle!" Du Peyrou, who perceived my transport, was ignorant of the cause, but will some day be informed: I hope, on reading this. The reader may judge by this impression, made by so small an incident, what an effect must have been produced by every occurrence of that time.
