Some of you may remember that a part of the course of lectures which your present lecturer delivered here last year were afterwards published in book-form, under the title of _The Science of English Verse_. Happening in the publisher's office some time afterwards, I was asked if I would care to see the newspaper notices and criticisms of the book, whereof the publishers had collected a great bundle. Most curious to see if some previous ideas I had formed as to the general relation between literary art and science would be confirmed, I read these notices with great interest. Not only were my suspicions confirmed: but it is perfectly fair to say that nine out of ten, even of those which most generously treated the book in hand, treated it upon the general theory that a work on the science of verse must necessarily be a collection of rules for making verses. Now, not one of these writers would have treated a work on the science of geology as a collection of rules for making rocks; or a work on the science of anatomy as a collection of rules for making bones or for procuring cadavers. In point of fact, a book of rules for making verses might very well be written; but then it would be a hand-book of the art of verse, and would take the whole science of verse for granted,--like an instruction-book for the piano, or the like. If we should find the whole critical body of a continent treating (say) Prof. Huxley's late work on the crayfish as really a cookery-book, intended to spread intelligent ideas upon the best methods of preparing shell-fish for the table, we should certainly suspect something wrong; but this is precisely parallel with the mistake already mentioned. But even when the functions of form, of science, in literary art have been comprehended, one is amazed to find among literary artists themselves a certain apprehension of danger in knowing too much of the forms of art. A valued friend who has won a considerable place in contemporary authorship in writing me not long ago said, after much abstract and impersonal admission of a possible science of verse--in the way that one admits there may be griffins, but feels no great concern about it--"_as for me I would rather continue to write verse from pure instinct_."
