fembles that part of the ftock in- compound trees, where it arifes, 



above mentioned a bud from the upper part 



th 



pie 



of the long caudexes, which form the filaments of the bark, would 

 become a golden pippin branch ; a bud from the middle part of them 

 would become a nonpareil branch ; and a bud from the lower part 

 a crab branch.. 



Thirdly, another wonderful property of this lateral mule progeny 

 of trees compounded by ingraftment cor 



fifl 



in 



th 



that the new 



mule may confift of parts from three, or four, or many parents, when 

 fo many different fcions are ingrafted on each other ; whence a ques- 

 tion may arife, whether a mixture of two kinds of anther- duft previ- 

 ous to its application to the ftigma of flowers might not produce a 

 threefold mule, partaking of the likenefs of both the males ?' 



6. On this nice fubje(El of reprodu6lion fo far removed from com- 

 mon apprehenfion the patient reader will excufe a more prolix invef- 



tigation. The attra£lion of all matter to the centres of the plan 



of the fun. is termed

th

other is generally called chemical affinity ; to which the attractions 

 belonging to ele6lricity and magnetifm appear to be allied. 



I 



thefe latter kinds of attract 



a 



feem to be 



required ; firft, the power to attradl poflefled by one of the bodies, 

 and fecondly, the aptitude to be attraded poffefled 



the other.. 



Thus when a magnet attra<fls iron, it may be faid to poflefs a fpccific 

 tendency to unite with the iron ; and the iron may be faid to poflefs 

 a fpecific aptitude to be united with the magnet. The former appears 

 to refide in the magnet, becaufe it can be deprived of its attractive- 

 power, which can alfo be reflored to it ;- and the iron appears to pof- 

 fefs a fpecific aptitude to be united with the magnet, becaufe no 

 other metal will approach it. In the fame manner a rubbed fl:ick of 

 fealing-wax may be faid to poflefs a fpecific tendency to unite with a' 

 light flrraw, but not with a glafs bead. Here the flraw feems to.
