208 NOVUM ORGANUM. 



as to the climate, soil, and depth at which each metal is gene 

 rated, and the same of gems whether produced in rocks or 

 mines, also as to the soil in which- particular trees, shrubs, 

 and herbs, mostly grow and, as it were, delight ; and as to 

 the best species of manure, whether dung, chalk, sea sand, 

 or ashes, &c. and their different propriety and advantage 

 according to the variety of soils. So also the grafting and 

 setting of trees and plants (as regards the readiness of 

 grafting one particular species on another) depends very 

 much upon harmony, and it would be amusing to try an 

 experiment I have lately heard of, in grafting forest trees 

 (garden trees alone having hitherto been adopted), by which 

 means the leaves and fruit are enlarged, and the trees pro 

 duce more shade. The specific food of animals again should 

 be observed, as well as that which cannot be used. Thus 

 the carnivorous cannot be fed on herbs, for which reason 

 the order of Feuilletans, the experiment having been made, 

 has nearly vanished ; human nature being incapable of sup 

 porting their regimen, although the human will has more 

 power over the bodily frame than that of other animals. 

 The different kinds of putrefaction from which animals are 

 generated should be noted. 



The harmony of principal bodies with those subordinate 

 to them (such indeed may be deemed those we have alluded 

 to above) are sufficiently manifest, to which may be added 

 those that exist between different bodies and their objects, 

 and, since these latter are more apparent, they may throw 

 great light when well observed and diligently examined 

 upon those which are more latent. 



The more eternal harmony and aversion, or friendship 

 and enmity (for superstition and folly have rendered the 

 terms of sympathy and antipathy almost disgusting), have 

 been either falsely assigned, or mixed with fable, or most 

 rarely discovered from neglect. For if one were to allege 

 that there is an enmity between the vine and the cabbage, 

 because they will not come up well when sown together, 

 there is a sufficient reason for it in the succulent and ab 

 sorbent nature of each plant, so that the one defrauds the 

 other. Again, if one were to say that there is a harmony and 

 friendship between the corn and the corn-flower, or the wild 

 poppy, because the latter seldom grow any where but in 

 cultivated soils, he ought rather to say there is an enmity 

 between them, for the poppy and corn-flower are produced 

 and created by those juices which the corn has left and re 

 jected, so that the sowing of the corn prepares the ground
