PREFACE. XXVJi 



&quot; wives breeding children, by some accident in their 

 &quot; own body.&quot;* 



Passing from these objections to the uses of natu 

 ral history, they are explained by Lord Bacon in the 

 treatise De Augmentisf and in the Novum Orga- 

 num. In the treatise De Augmentis, the subject 

 of Natural History is thus exhibited. 



I. As to the Subject or History. 



1. Of Nature in Course. 



1. Of Celestial Bodies. 



2. Of the Region of the Air. 



3. Of the Earth and Water. 



4. Of the Elements or Genera. 



5. Of the Species. 



2. Of Nature wandering or Marvails. 



3. Of Arts. 



II. As to its use. 



\ . In the Knowledge or History Narrative. 

 2. In being the primitive matter of Philosophy, 

 which he says is defective, and to supply this defect, 



* There are in different parts of the Sylva Sylvarum facts 

 evincing Bacon s life of mind, and faculty of generalizing 

 from his earliest infancy. See Art. 946, p. 508, when his mind is 

 at work upon the nature of imagination, most probably before he 

 was 12 years old, when he quitted his father s house for the 

 university, from whence at 16, he went with Sir Amyas Paulet 

 to Paris, and returned after his father s death. Sec also Art. 

 151, page 91, when in Trinity College meditating upon the 

 nature of sound. See also Art. 140, page 87, and 148 page 89, 

 and Art. 248, page 127. 



t There is considerable difference between the arrangement 

 of th:s part in the Advancement and the De Augmentis.
