What is the passage of matter through matter?

The human body combines all the materials, and gases found on—and in—the earth, and its atmosphere. 

The subdivisions of matter are so minute that even the speck of dust, which floats invisible to the eye (unless a sunbeam illuminates it) is composed of an infinite number of smaller particles, which are attracted, and held together, by the same laws that govern the attraction and repulsion of larger bodies.

Spirits who wish to materialise collect the atoms suitable for their purpose from the atmosphere, and—

Using their will—

Shape and hold these atoms into the form of their earthly bodies. 

Spirits who possess the knowledge of the laws governing the combination and adhesion of the various substances are able to adapt atoms to their own use and to make a body.  

Possession of a sufficient amount of the elixir of life—

The mysterious and ethereal chemical substance, or essence, found in all living things—

Enables the spirit to clothe himself in the atoms he has collected—

And to hold them long enough to melt them, as it were, into a state, which will take on his identity, or the stamp of his individuality. 

On the other hand, the absence of this essence causes him to lose his hold before the process has perfected, and he shows himself hastily and imperfectly, or else does not show himself at all. 

In other words, a spirit takes the ready-prepared atoms given off by every living thing in nature, and artificially digests, or arranges them into a material covering, or envelope, with which to clothe himself and make him visible to material sight. 

Every atom of your earthly body is drawn, directly or indirectly, from the atmosphere around you, and absorbed in one form, or another—

And after it has served, as clothing for your spirit, it is cast off to be absorbed again in another form by some other living thing.

The fluidic ether holds the material body together in life. 

At death—

Or, more correctly—

The withdrawal of the soul, and the severance of the connecting link between it, and the material atoms of the body, it escapes into the surrounding atmosphere, permitting the particles of that body to decay. 

Cold retards the dispersal of this fluid ether—heat accelerates it. 

This explains why the body of any animal, or plant, disintegrates, or turns to decay sooner in hot than in cold climates, and becomes nourishment fit for those minute parasites, which are stimulated, and fed by a lower degree of life magnetism, which is retained in the discarded envelope.
