This is an essay book. Benvenuto Cellini tells us that when, in his boyhood, he saw a salamander come out of the fire, his grandfather forthwith gave him a sound beating, that he might the better remember so unique a prodigy. Though perhaps in this case the rod had another application than the autobiographer chooses to disclose, and was intended to fix in the pupil's mind a lesson of veracity rather than of science, the testimony to its mnemonic virtue remains. Nay, so universally was it once believed that the senses, and through them the faculties of observation and retention, were quickened by an irritation of the cuticle, that in France it was customary to whip the children annually at the boundaries of the parish, lest the true place of them might ever be lost through neglect of so inexpensive a mordant for the memory. From this practice the older school of critics would seem to have taken a hint for keeping fixed the limits of good taste, and what was somewhat vaguely called classical English. To mark these limits in poetry, they set up as Hermae the images they had made to them of Dryden, of Pope, and later of Goldsmith. Here they solemnly castigated every new aspirant in verse, who in turn performed the same function for the next generation, thus helping to keep always sacred and immovable the ne plus ultra alike of inspiration and of the vocabulary.
