The two volumes before us, in addition to the prefaces and biography, embrace the _Novum Organum_, 'the _Parasceve_,' and the work _De Augmentis Scientiarum_. It is to be regretted that the English versions, corrected by BACON himself, were omitted, but those who would read the translations are mostly capable of reading 'Baconian Latin.' As they are, they will be most gratefully accepted by thousands. The forthcoming volumes will embrace the English works. We would here wish that the editor had not, as he informs us he has done, modernized the spelling,--but here the majority of readers will perhaps be thankful that such is the case. As regards typography, paper, and all outward grace, this edition leaves literally nothing to be wished for, while a short critical article on the portraits of BACON leads us to infer that the exquisitely engraved head of the philosopher, given in the first volume, has been made accurate at the cost of great research and labor. THE OLD LOG SCHOOLHOUSE. By Alexander Clark, Editor of _'Clark's School Visitor.'_ Philadelphia: Leary, Getz & Co. Mr. CLARK is the most modest of writers; one in whose writings unaffected simplicity and freedom from literary conceit is manifest on every page. He appears in all the many sketches which constitute this volume to have written for the direct purpose of pleasing and teaching youthful readers or quiet and pious grown persons. He neither eyes the world through a lorgnette or a lorgnon, nor affects a knowledge of all things, nor even hints at it. Yet it is precisely in this that the charm of his stories consist--they are perfectly rational, and told in the plain language which becomes them. It is to be desired that Mr. CLARK will give us a volume of sketches devoted entirely to that Western and rural life which he sketches with such felicity. SONGS IN MANY KEYS. By Oliver Wendell Holmes. Boston: Ticknor & Fields, 1861.
