Containing a Treasury of Pythagoric and Platonic Physiology

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. When I speak however, of the perspicuity with which these particulars are derelriped, I do not mean that they are delivered in such a way, as to be obvious to every one, or that they may be apprehended as soon as read for this pertains only to the fungous and frivolous productions of the present day; but my mean ing is, that they are written with all the clearness, which they are naturally capa ble of admitting, or ‘wlnch agennine student of the philowphy’ of Plato can desire. And this leads me to make some remarks on the iniquitous opinion which, since the rental of letters, has been generally entertained ofthe writings of l’roclns and other philo~opher~4, who are distinguished by the appellation of the latter l’lato hists, and to show the eanse from which it originated.
