Faraday to Misses Hawes   10 December 1848¹

Mr. Faraday presents his Compliments to the Misses Hawes and though anxious to take advantage of the honor of their invitation is constrained to remain at home on the 11th for those who have charge of his health say it must be so. May it be long before the Misses Hawes have any consciousness of the necessity of such caution and may a lengthened prosperous & happy life be theirs[.]
