I had the Pleasure of hearing a few Days since that you were so when Mr Vaughan left Boston, but he brought no Letters. We have long expected Cousin Jonathan, but he does not appear. If he is still there, give him the Pamphlet you will receive with this. If gone, keep it for yourself. In my last I inform'd you that I had receiv'd the Soap, and that it was very solid and firm, not showing the least Disposition to crack, and seems otherwise very good.

My Love to your Children, and believe me ever
Your affectionate Brother
Love to Cousin Williams
