Note 433 — TUESDAY, AUGUST 31.

This book has given rise to much enquiry, which has ended in ludicrous surprise. Several ladies, wishing to learn the kind of reading which the great and good Dr. Johnson esteemed most fit for a young woman, desired to know what book he had selected for this Highland nymph. 'They never adverted (said he) that I had no choice in the matter. I have said that I presented her with a book which I happened to have about me.' And what was this book? My readers, prepare your features for merriment. It was Cocker's Arithmetick!—Wherever this was mentioned, there was a loud laugh, at which Johnson, when present, used sometimes to be a little angry. One day, when we were dining at General Oglethorpe's, where we had many a valuable day, I ventured to interrogate him. 'But, Sir, is it not somewhat singular that you should happen to have Cocker's Arithmetick about you on your journey? What made you buy such a book at Inverness?' He gave me a very sufficient answer. 'Why, Sir, if you are to have but one book with you upon a journey, let it be a book of science. When you have read through a book of entertainment, you know it, and it can do no more for you; but a book of science is inexhaustible.' BOSWELL.
