In R. Haim Jos. David Azulay's travelog מעגל טוב there is an interesting passage (one of many) which records events that took place on January 6-7, 1766:
"We departed from Nice at noon . . . and crossed two mountains and a hill . . . we came upon a mountain with such deep snow that we could even stand; us and all of our things sank into the snow. So we hired four gentiles to assist us . . . It was a sunny day and I was wearing two samaras2 and two pairs of socks, but even so I was in great distress from the cold. It was a good thing I had chocolate with me - I ate more than a litre!
1 The title is from Proverbs 2.9.
