be at tr a fled. A magnet pojpjjes power to attracl, Iron an aptitude 

 to be attracted. So of electrified bodies , and chemical affinities. 

 Or two bodies may reciprocally attract each other. 7. Union of 

 animal with inanimate matter. Union of two living particles. 

 'The animal fenfe poffejjes appetency to unite, the inanimate materi- 

 al pojjejjes aptitude to be united. Vitality of the blood. Fibrils 

 with appetencies, molecules with propenftties* 8. Fibrils with 

 formative appetencies. Molecules with formative propenfities. 

 Like Jingle and double affinities. PaJJtons of hunger and of love. 

 Thirjl. Suckling children. Mode of lateral propagation. 9. 

 Superfluous vital particles produced in the blood. Secreted by fex- 

 ual glands. Combine beneath the cuticle of trees. Acquire new 

 appetencies, and form fecondary parts of the embryon. So the 

 paffton for generation > and defire for animal food, and the new at- 

 traElions of bodies chemically combined. New molecules are form- 

 ed by the fexual glands at puberty, and in the pectoral ones. 10. 

 Different fibrils and molecules are detached from different parts 

 of the parent caudex to form the filial one : fo in the fexual propa- 

 gation of vegetables : and by their combination produce an embry- 

 on) and acquire new appetencies and form fecondary parts, as in 

 dioecious flowers. II. Threefold lateral mules* So fexual mules 

 refemble parts of their parents according to the combinations of the 

 fibrils and molecules , and produce fecondary parts, other wife they 

 would refemble the father only. Epigram from Martial. IX. 

 I . Various parts of the new embryon produced at the fame time. 

 Organized bodies too large to befecreted. Primary and fecondary 

 formation of parts of the fetus. M. Buffon's theory differs from 

 this. Moles and monjlrous births. An embryon is not an in- 

 dividual > till the nerves unite in the brain. 2. The brain and 

 heart generated at the fame time. 3. Organic particle too large 

 to pafs the glands and capillaries. Not fo the formative particles. 

 Hence the latter cannot combine in the blood. 4. Formative par- 

 ticles do not combine in the receptacles of the fexuat glands > as thofs 

 of the male differ from thofe of the female. Not fo in Bufforfs 

 theory. 5. "The whole embryon not produced at the fame time. 

 Primary and fecondary parts. Secondary formation of the caudex 

 of buds > of diffevered earth worms > of the legs of crabs, of human 

 teeth ', and of a thumb. X. I. Solitary lateral generation, and 

 folitary internal generation. Animalized particles of primary 

 combination, are fecreted ^combine y and form primary organizations. 

 The caudex gemma produce fecondary parts, and commences its 

 formation in federal places at the fame time. Refembles the parent 

 more than a fexual progeny. The polypus and hydra. 2. Solita- 

 ry internal generation of aphis, tenia, aclinia 9 votvcX) produces a 

 viviparous offspring^ not an oviparous one. Difference of lateral
