66 Chemical Affinities. 



sioninahomogeneousfluid. All the crushed and churned matter 

 in the stomach is reduced to a uniform liquid pap or mass, 

 which in its turn is raised to a uniform standard ofe 

 heat, and then it is passed on, to be presently taken up 

 into the blood (and expelled in part as effete from the 

 system) by a series of tubes and vessels which, in the 

 case of veins 9 let in much fluid and permit little to exude 

 and lacteals, which take up the more dense particles y 

 each to remix in the double blood reservoir of admixture and 

 purification the heart and lungs from which they depart to 

 be diffused and to irrigate by self-appropriation a 11 the tissues 

 of the body. 



Between entrance as raw material, and exit as effete 

 matter, every particular particle has been reduced to succes- 

 sive changes in a moist or fluid condition, accompanied with 

 a relative amount of fixed or free caloric ; and, according to- 

 the balance of materials and the caloric set free or appro- 

 priated by each particular particle, so are the changes in 

 eclectic attraction ever undergoing successive orders of com- 

 binations and dissolutions till restored back to the inorganic 

 kingdom. 



That which takes place in organized beings in regular 

 order of succession is, in principle, going on in the chemical 

 laboratories of the manufactories of various kinds of 

 material of human device and ingenuity. 



In principle, the eclectic attraction is a series of atomic 

 and synatomic or molecular changes, that, in their respective 

 attractions for each other, show the greatest variety in their 

 degrees of attraction, as in bone, membrane, muscle, and 

 areolar tissue ; and which, with few exceptions, change 

 their mutual affinities when placed beyond given ranges of 

 temperature, or when placed under great pressure by sur- 

 rounding substances. 



No doubt the fluid caloric, in giving molecules and atoms-
