With respect to the measles, they began in Mr. Randolph's family about the middle of June, and will probably be a month getting through the family; so you had better, when you go, pass on direct to Monticello, not calling at Edgehill. I will immediately write to your sister, and inform her I advised you to this. I have not heard yet of the disease having got to Monticello, but the intercourse with Edgehill being hourly, it can not have failed to have gone there immediately; and as there are no young children there but Bet's and Sally's, and the disease is communicable before a person knows they have it, I have no doubt those children have passed through it. The children of the plantation, being a mile and a half off, can easily be guarded against. I will write to Monticello, and direct that, should the nail-boys or any others have it, they be removed to the plantation instantly on your arrival. Indeed, none of them but Bet's sons stay on the mountain; and they will be doubtless through it. I think, therefore, you may be there in perfect security. It had gone through the neighborhood chiefly when I was there in May; so that it has probably disappeared. You should make inquiry on the road before you go into any house, as the disease is now universal throughout the State, and all the States. Present my most friendly attachment to Mr. and Mrs. Eppes. Tell the latter I have had her spectacles these six months, waiting for a direct conveyance. My best affections to Mr. Eppes, if with you, and the family, and tender and constant love to yourself. TH. JEFFERSON. P.S.--I have always forgotten to answer your apologies about Critta, which were very unnecessary. I am happy she has been with you and useful to you. At Monticello there could be nothing for her to do; so that her being with you is exactly as desirable to me as she can be useful to you. On the 16th of July he wrote Mrs. Eppes:
