Historia Philosophise Graecae. Testimonia Auctorum conlegerunt Notisque instruxerunt H. RITTER et L. PRELLER. Pars prima septimum edita. Physicorum Doctrinae recognitae a FR. SCHULTESS. Gothae : Sumpti- bus Fridr. Andr. Perthes, 1886. Pp. viii., 180. First published in 1838, revised by Preller for a second edition in 1857, and then issued in successive editions without further change till taken in hand by Teichmuller for a sixth in 1878, the collection of Greek (or Latin) extracts, with Latin notes, that has served students of Greek philosophy so well through half a century, here begins, in a seventh edition, to be brought up fully to the level of the latest and best research in the subject. In no department has later inquiry been so active and fruitful as in that of the early " Nature-philosophy," and it is to this that the new editor (known by his Platonic studies) has for the present confined his labours, without giving any definite promise as to the remainder of the work. The part is increased by about half as much matter again as it contained on finally leaving Preller's hands, and otherwise appears in a considerably altered form. Preller's division of Ionics Pythagoreans Eleatics and Empedocles, substituted -for the original division into supporters of a single mutable principle and supporters of one or more immutable principles, now gives place to a general ordering of the "Physici" in chronological succession, with the result that Empedocles is separated from the Eleatics by Anaxa- goras, and is now followed by Leucippus and Democritus, with Diogenes, Archelaus and Hippo bringing up the rear. The additions (or substitu- tions) are made pretty uniformly throughout, and affect the extracts as well as the notes, though of course it is in the latter that the remarkable thoroughness of the editor's work becomes most apparent. Marginal indi- cation of the subjects of paragraphs is a new and very welcome feature. RECEIVED also : G. S. Fullerton, The Conception of the Infinite, Philadelphia, J. B.
