(Extract of a letter by Mr. Euler to Mr. Bernoulli father concerning the memoire published by them in 1771, p. 318)


This is a very short note about properties of the numbers 10p, along with criteria for them to be divisible by 2p+1. It also contains a remark that 231-1 is prime and that 41 - x + xx produces prime numbers for x up to 40.
