similarity between the telegraph switch and the animal brain. 
From the battery only two wires, one from either pole, lead the 
force to the switch; yet from this switch any number of wires 
may radiate, each one endowed with equal magnetic force, 01 the 
whole may be concentrated in one. From our stomach two 
cords also lead up the spine to the base of the brain, (which may 
be compared to the telegraph switch,) and from the brain the 
whole nervous system of the human body proceeds. 
The inference to be deduced from this wonderful coincidence 
is, that the body is merely a machine, whose brain is controlled 
by the magnetism of the body; the mznd being the telegraph 
operator. 
An animal is thus as much a magnet as a plant, and its life is 
magnetism. 
In concluding our argument that magnetism is the life of the 
world, if we have proved that minerals, plants and animals all 
live and grow by magnetism, then it only remains to show that 
the earth isa magnet; but this is a well established and ac- 
knowledged fact, and thus it is only making more certain what is 
sure, by proving plants and animals magnets; for the invariable 
law of magnetism is, that every atom of a magnet, no matter 
how connected, is also a complete magnet as well as a part of 
the whole.

AFTER I read my essay “On the Fossiliferous Rocks of Arisaig,” 
before the Halifax Literary and Scientific Society, in April, 1859, 
a notice appeared. in the Presbyterian Witness newspaper, in 
which the editor stated “that I had settled questions that had 
puzzled Lyell and Dawson,” regarding the age of the Arisaig 
rocks, y
