THE ANIMAL KINGDOM.

very origin of the mother, though it does not a flu me its own proper exiftence till it be 

 furnilhed, by impregnation, with the paternal heart. From this it follows, that equivocal 

 generation is an impoflible abfurdity. 



The hydraulic animal machine refembles that of vegetables, but is exclufively con- 

 joined with a vail number of faculties which are lodged in, or are dependent on the 

 ftructure of, the brain. The foft internal medullary pith ftretches out from the brain, 

 as from a bulbous root, into a fimplejlem, which is infinitely fubdivided in its courfe, 

 and fends out nervous filaments, fimilar to itfelf, for the fupply of every part of the 

 body. The hardened inward woody matter, which, covering the former, arifes from the 

 fkull as from a root, elongates into the vertebral ft cm, is articulated by moveable joints, 

 and branched with oppofite boughs ; to thefe are attached the fibrous, flefliy, and con- 

 tractile mufcles, analogous to leaves, fpreading in determinate order, and having their 

 extremities fixed to the neareft joints. The external cortical fubftance is rooted inter- 

 nally in the lacteals, meets together in the heart, as a bulb, and fpreads out in a double 

 and fimilar vafcularyfow, which branches fimilarly into infinitely ramified double twigs ; 

 from the extreme bifurcation of thefe arife the genital parts of fructification. 



The interior faculties of the animal machine are, ifl, The animal, electric, motive 

 faculty, or artifan of its divine life ; this, acting fecretly within the organized bulbous 

 brain, wills and thinks, and, fpreading its influence through the electrical threads of 

 the nerves, rules and governs the whole machine. 2d, The vital pneumatic facult) r , 

 which, refiding in the lungs, abforbs the vital principle from the air for fupporting 

 animal heat, and for preferving the living principle. 3d, The natural hydraulic facul- 

 ty, which refides in the vafcular fyftem, and originates from the perpetually moving 

 heart; this alternately receives the fluids from, and propels them to, every part of the 

 machine, adding or taking them away according to neceflity, and perpetually guarding 

 againft deficiency or redundance. 4th, The digeftive faculty, which, refiding in the 

 alimentary canal, prepares proper juices for being taken up by the lacteal veffels, which 

 carry them into the fyftem, for the nourifhment and fupport of the whole. 5th, The 

 genial fpermatic faculty, which is placed at the extremity of the trunk containing the 

 animal and natural faculties ; this conjoins the influence of the nervous and vafcular 

 organs, and gives origin to a diflinct animalcular machine, in every refpect fimilar to 

 the parent flock. 



The inftruments of the fenfes are phyfical organs, placed at the extremities of nerves 



derived immediately from the brain : Through the influence of thefe the animal, by a
