'A pleasing instance of the generous attention of one of his [Dr Johnson's] friends has been discovered by the publication of Mrs. Thrale's collection of "Letters". In a letter to one of the Miss Thrales, he writes,-- "A friend, whose name I will tell when your mamma has tried to guess it, sent to my physician to enquire whether this long train of illness had brought me into difficulties for want of money, with an invitation to send to him for what occasion required. I shall write this night to thank him, having no need to borrow".'
