'. . . From the Seventh Book, which is the longest and most valuable, is derived a large part of our knowledge of 

 Greek geometry. Many of the writings here analysed are nolonger extant, and it is on the indications (e. .7. Euclid'* 

 P<./-i\sm.s) which Pappus gives of the object or the contents of them that the geometers of the ITth and ISth Centuries- 

 relied for their restorations of these writings. . . . Several of the books contain impoitant theorems, tlie discovery of 

 which is probably due to Pappus himself. One of these has been long associated with the name of Guldinus (1577-1(543), 

 •Some others have received a brilliant development from the mathematicians of modem times.' 



' He discovered the directrix in the conic sections. In mechanics Pappus showed that the centre of a mass of a 

 triangular lamina is the same as that of an inscribed triangular lamina whose vertices divide each of the sides of the 

 original triangle in the same ratio. He also di.scovered the two theorems on the surface and volume of a solid of 

 revolutioTi which are still quote! in text-books under his name.' — W. W. R. Ball.

 The first book 'Of the generations of Naturall things' contains an account of how to generate artificial men 



(htimiiuciiii), of the secret potson of the basilisk, and many similar stories of Renaissance superstition. 



' Paracelsus was the man who, in the first half of the XVI. century, opened out new paths for chemistry and medicine 



by uniting them both. To him is undoubtedly due the merit of freeing chemistry from the restraining fetters of alchemy, 



by a clear definition of scientific aims. He taught that 'the object of chcmibtry is not to make gold, but to prepare 



medicines, "—Pyo/. E. v. M>'yer.
