VI PREFACE. 



Temporis Partis Masculus ... ... 478 



Epistolae 480 



Ornamenta Rationalia (T.) 492 



The tracts to which I have annexed the letter 

 G are taken from the publication of posthumous 

 tracts by Gruter. 



The tract entitled &quot; Partis instaurationis secundas 

 delineatio et augmentum,&quot; is a portion of the 

 tract in Gruter entitled &quot; Indicia vera de Inter- 

 pretatione nature :&quot; The beginning of this tract, 

 from the words &quot;Qui de natura&quot; to the words 

 &quot;judicio suo utetur&quot; is omitted. It is the same 

 as the preface to the Novum Organum, which will 

 be found in page 185, of vol. ix, of this edition. 



The tracts to which T is annexed are from Arch 

 bishop Tenison s Baconiana, published in 1679 : and 

 those to which R is annexed are from the Opus- 

 cula, published in 1658, by Dr. Rawley. 



The particulars of the tract &quot; De Sapientia Vete- 

 rum,&quot; which was published by Lord Bacon in the year 

 1609, are explained in the preface to the third 

 volume of this work : and the tract entitled 

 &quot; Meditationes Sacra?/ which was published in 

 1597, is explained folio xxiii, of vol. i. 



The Parasceve was published by Lord Bacon in the 

 Year 1620, in the conclusion of the &quot; Novum Orga- 

 num.&quot; It ought to have been inserted in the conclu 

 sion of volume ix, or at the commencement of vol x. 



The tract entitled &quot; Redargutio&quot; was first pub 

 lished by Stephens, in 1760, in a volume which also 

 contains the first tract entitled &quot;Temporis Partus
