PREFACE. 191 



stauratio, in some of its forms ; probably to the 

 Temporis Partus Masculus. 



19. Francisci Baconi Topica Inquisitionis de Luce et 

 Lumine. (p. 485.) Another copy, with a few 

 slight variations, of the paper which has been al 

 ready printed (Vol. IV. p. 133.) from Dr. Kaw- 

 ley s copy. 



Of these nineteen pieces, the last thirteen are (as I 

 have said) distinguished from the others by a general 

 running title of Impetus Philosophici ; the 2nd, 3rd, 

 4th, 5th, and 6th carrying each its own title on the 

 top of its own pages ; and to the whole volume is pre 

 fixed an address from Gruter to the reader, which con 

 tains all the information that is to be had about it ; 

 and which I must transcribe at length, the meaning 

 being in some places so obscure that I can only 

 guess at it.

 mate circumferuntur, hue translata ob materiae cognationem. 

 Titulus quern frons libri praefert et totum complectitur opus- 

 culi in varias dissertationes secti argumentum, ab ipso Veru- 

 lamio est ; quern singular exhibent pagina? ex rerum tracta- 

 tarum serie distinctum, a me, ut minus confunderet quaerentem 

 Lectoi em indiculi defectus. Quicquid sequitur, ab eo loco 

 cujus inscriptio est in ipso contextu Indicia vera de interpre-
