A DISSERTATION ON THE PHILOSOPHY OF ARISTOTLE, in four Books; in which his principal Physical and Metaphysical Dogmas are unfolded; and it is shown from indubitable evidence, that his Philosophy has not been accurately known since the destruction of the Greeks. The insufficiency also of the Philosophy that has been substituted by the Moderns for that of Aristotle is demonstrated. This volume was written as an Introduction to the Translation of Aristotle’s Works. 4to. 5_l._ 5_s._ _boards_. THEORETIC ARITHMETIC, in three Books; containing the Substance of all that has been written on this Subject by Theo of Smyrna, Nicomachus, Iamblichus, and Bœtius.—Together with some remarkable particulars respecting perfect, amicable, and other Numbers, which are not to be found in the writings of any ancient or modern Mathematicians. Likewise a Specimen of the manner in which the Pythagoreans philosophized about Numbers; and a Developement of their mystical and theological Arithmetic, 8vo. 14_s._ _boards_. ORPHIC FRAGMENTS, hitherto inedited. See No. XXXIII. of the CLASSICAL JOURNAL.
