PREFACE. IX 



those which he put in his Catalogue of the Magnalia 

 Naturae. And, doubtless, his Lordship undertook both a 

 great and a most desirable work, of making art short, and 

 life easy and long. And it was his Lordship s wish, that 

 the nobler sort of physicians might not employ their times 

 wholly in the sordidness of cures, neither be honoured for 

 necessity only ; but become coadj utors and instruments of 

 the divine omnipotence and clemence, in prolonging and

 signed to select certain subjects in nature or art; and, as it 

 were, to draw to the sense a certain scheme of the beginning 

 and progress of philosophical disquisition in them ; show 

 ing, by degrees, where our consideration takes root, and 

 how it spreadeth and advanceth. And some such thing is 

 done by those who, from the Cicatricula, or from the 

 Punctum Saliens, observe and register all the phsenomena
