We fancy it is long since Miss Leslie, Miss Gould, Miss Sedgwick, Mrs. Sigourney, Lytton Bulwer, and Ben D'Israeli have been so affectionately patted on the back. Of Mr. Mattson's _style_ the less we say the better. It is quite good enough for Mr. Mattson's matter. Besides--all fine writers have pet words and phrases. Mr. Fay had his "_blisters_"--Mr. Simms had his "_coils_," "_hugs_," and "_old-times_"--and Mr. M. must be allowed his "_suches_" and "_so muches_." Such is genius!--and so much for the Adventures of an Enthusiast! But we must positively say a word in regard to Mr. Mattson's _erudition_. On page 97, vol. ii, our author is discoursing of the novel which his hero is about to indite. He is speaking more particularly of _titles_. Let us see what he says. "An ill-chosen title is sufficient to condemn the best of books. Never does an author exhibit his taste and skill more than in this particular. Just think for a moment of _the Frenchman's version of Doctor Johnson's 'Rambler' into 'Le Chevalier Errant,' and what was still more laughable, his innocently addressing the author by the appellation of Mr. Vagabond!_ By the way, the modern fanatics were somewhat remarkable in the choice of their titles. Take for example the following--_'The Shop of the Spiritual Apothecary' and 'Some fine Baskets baked in the Oven of Charity, carefully conserved for the Chickens of the Church, the Sparrows of the Spirit, and the Sweet Swallows of Salvation.'_" Having admired this specimen of deep research, let us turn to page 125, vol. ii. Mr. Ulric is here vindicating himself from some charges brought against his book. Have patience, gentle reader, while we copy what he says.
