grow more ftraight : the concave parts of them drawing more 

 towards the funne, becaufe he extra&eth and fucketh their moy- 

 ftuve from their hinder parts into their former, that are more 

 expofed to his beams; and thereby the hinder parts are con- 

 trafted and grow fhorter,and thofe before grow longer. Which 

 if it be in excefle, maketh the leaf become crooked the contrary 

 way, as we fee in divers flowers, and in fundery leafs during the 

 fummers heat : witncfle, the Ivie, Rofes full blown, Tulips, 

 and all flowers in form of bells : and indeed all kinds of flow- 

 ers whatfocvcr, when the funne hath wrought upon them to 

 that degree we fpeak of, and that their joyning to their flalk, 

 and the next parts thereunto, allow them (cope to obey the 

 impulfe of thole outward caufes. And when any do vary from 

 this rule, we (hall as plainly fee other manifert caufes produ- 

 cing thole different effects, as now we do thefc working in this 

 manner. 



As for fruits though we fee that when they grow at liberty 

 upon the tree, they ieem to have a particular figure allotted 

 them by nature : yet in truth, it is the ordered feries of natu- 

 rall caufes and not an intrinfecall formative virtue which, brccti- 

 eth thisefrec-t, as is evident by the great power, which a;rt hath 

 to change their figures at plcafurc : whereof you may fee ex- 

 amples enough in Campanella, and every curious gardner can 

 furnifli you with ftore. 



. Out of thefe, and fuch like principles a man that would make 



The fame ap- it his ftuddy with lefle trouble or tcdioufncfle, then that patient 

 5ie$ofAnim^u contemplator of one of natures little w ork$ ( the Bees } .whom 

 we mentioned a while agone, might without all doubt trace the 

 caufes in the growing of an Embryoa, till he difcovered the 

 reafon of every bon.es figure ; of every notable hole or pat- 

 fage that is in them : of the ligaments by which they arc 

 tied together : of the membranes that cover them, and of all 

 the other parts of the body. How, out of a firft mafle , 

 that was loft, and had no fuch parts diftinguifhable in it, 

 every one of them came to be formed, by contracting that 

 marfe in one place, by dilating it in another, by moyft- 

 ning it in a third , by drying it here , hardening it 

 there ;
