It is pleasing to observe in what a prophetic spirit this prayer of an affectionate father in the close of his letter was drawn up; for such, in all these particulars, was Mr. Malthus, and such he remained to the last moment of his life.
To illustrate still farther the remark we have made of the manner in which the graver instruction of his father was mingled with lighter matters intended for the same purpose, it may be interesting to add another extract from one of his letters to him at Cambridge:
"MY DEAR BOB,
"I find you are not yet in your new rooms. I heartily hope they will prove agreeable to you. We should have been truly glad to have seen you here in the leisure of Christmas, and would have subscribed to your journey; not that I used to think Oxford the less pleasant, and certainly not the less useful for being disburthened of some of its society: I imagine you will say the same of Cambridge.
"I have always found that one of my greatest comforts in life was the delight I have ever taken in solitude—if, indeed, one can give that name to anything which is likely to happen to you or me.

thermometer was upon a north wall at a distance from the house.
Did not I ask you whether you had got my Theocritus with you?
