All seasons of the year come and go, and we see year in and out the perpetual processes of construction of one class of bodies, and the passing away of others.
Vegetation builds forests, and cold builds mountains of ice to be dissolved and sent into the ocean to purify the water, and keep the brines from drying to powder, as salt.
PROCESSES OF LIFE MUST BE KEPT IN MOTION.
All the processes of earth-life, must be kept in perpetual motion to cultivate and be kept in healthy condition, or the world would wither and die, and go to the tombs of space, to join the funeral procession of other dead worlds. Thus you see all nature comes and goes by the fiat of wisely adjusted laws.
NO SATISFACTION FROM AUTHORS.
Read all the authors from Æsculapius to this date, and all combined leave the inquirers without a single fact as to the cause or causes of fever.
One says fever may come from too much carbon. Another says chemical defects may be the cause.
I would like to agree with some of the good men of our date or the ancient theorists if I could, but they, both dead and alive, are a blank except the tons of paper they have covered all over with conjectures, and closed out by the words "Perhaps so's and howevers" spoken in all tongues and languages on earth.
All have explored for centuries for the cause of fevers, and on return from their multiple voyages say, we hope some day to find the cause. We have killed many dogs experimenting, but have failed to find the cause of fever.
