--"When I feel inclined to read poetry I take down my Dictionary. The poetry of words is quite as beautiful as that of sentences. The author may arrange the gems effectively, but their fhape and luftre have been given by the attrition of ages. Bring me the fineft fimile from the whole range of imaginative writing, and I will fhow you a fingle word which conveys a more profound, a more accurate, and a more eloquent analogy."-- --"Once on a time, a notion was ftarted, that if all the people in the world would fhout at once, it might be heard in the moon. So the projectors agreed it fhould be done in juft ten years. Some thousand fhip-loads of chronometers were diftributed to the selectmen and other great folks of all the different nations. For a year beforehand, nothing else was talked about but the awful noise that was to be made on the great occafion. When the time came, everybody had their ears so wide open, to hear the universal ejaculation of BOO,--the word agreed upon,--that nobody spoke except a deaf man in one of the Fejee Islands, and a woman in Pekin, so that the world was never so ftill fince the creation."-- There was nothing better than these things and there was not a little that was much worse. A young fellow of two or three and twenty has as good a right to spoil a magazine-full of essays in learning how to write, as an oculist like Wenzel had to spoil his hat-full of eyes in learning how to operate for cataract, or an ELEGANT like Brummel to point to an armful of failures in the attempt to achieve a perfect tie. This son of mine, whom I have not seen for these twenty-five years, generously counted, was a self-willed youth, always too ready to utter his unchastised fancies. He, like too many American young people, got the spur when he should have had the rein. He therefore helped to fill the market with that unripe fruit which his father says in one of these papers abounds in the marts of his native country. All these by-gone shortcomings he would hope are forgiven, did he not feel sure that very few of his readers know anything about them. In taking the old name for the new papers, he felt bound to say that he had uttered unwise things under that title, and if it shall appear that his unwisdom has not diminished by at least half while his years have doubled, he promises not to repeat the experiment if he should live to double them again and become his own grandfather. OLIVER WENDELL HOLMES. BOSTON. Nov. 1st 1858. CHAPTER I I was just going to say, when I was interrupted, that one of the many ways of classifying minds is under the heads of arithmetical and algebraical intellects. All economical and practical wisdom is an extension or variation of the following arithmetical formula: 2+2=4. Every philosophical proposition has the more general character of the expression a+b=c. We are mere operatives, empirics, and egotists, until we learn to think in letters instead of figures.
