[salute] My Dear Brother
As my thoughts are Principally busied upon the French tongue, & as I wish you to turn yours the same way, earlier than I did, I cannot
{p. 100}
think of a Subject to write to you upon more agreable & useful both to you & me than this: Pappa who has an opportunity of Conversing with many men of Learning in this Kingdom, among the phisiciens & Lawyers, as well as eclesiasticks, of various orders, particularly with several very learned abbys,
1 he has made it his buisiness to enquire after the best books, & other helps for learning the language of this nation
2 in some future letters to my brother Charles & you, I will give you a List of the grammers, Dictionarys, & treatisies upon the French tongue which he has collected as I have the use of this little library if I do not make myself master of French it will not be for want of opportunity or of books but that this talent with which Providence has intrusted
3 me may be improved to the best advantage it is necessary to be a good husband of my time.
I cannot impress too strongly upon my mind or recommend too warmly to you the importance of a sentence
4 which I lately read in a French writer “tous les momens de 1'enfans sont precieux”
5 with which I take my Leave of you and subscribe myself your affectionate Brother
