NaHura Consisting Of Salts.

In using the word salts here 20 desig-
nate class Of maaures, I wish 20 dss-
llaguish between these and riinrral ma
nures. as they are usua IL termed. These
manurrs are similar in kind 20 tie salts

are derived from lhr animal kingdom

They are animal salis. Here. then, let
us divide the second class Of manures in-

source Of these animal s,ll.. llhas been

divided into iwa classes; that which does

all domestic animals eat these classes.
In few words, let Us trace their course

list. tnn. il the course Of most alkaline
salts taken into the body. They pass of
in urine. Here, then, we came to the
suhjec, quite prepared to understand it.
The urine Is collection Of salts, some
are Of mineral. other nf animal origin. But
tina, which gives the urine lis peculiar
characteristic properties. is substance
formed from the heterogeneous fnp,, and
termed UREA. Now you need hardy
t:oulle yourself to remember this new
name; all | want you 10 understand shout
it is, that when urine is exposed to air il
r,ts, and this peculiar substance is chan
gel 10 ammonia. This is the pniu' to be
remembered. In considering urine there

10 point out further the mode Of its action,
than to refer thai Of every animal, To its
salts and power Of forming ammonia. The
quantity OF the last will he in proportion
% the quantity Of urea. There ARE "ther
salts Of ammonia IN urine, and also mime
gal salts. These affect but lillle The value
Of urine rs n manure.
II is the urea, essence OF urine, that
substance which forms ammonia IN rot
ting urins, winch makes this liquid more
valuable than dung. Hence. reader. ifthls
i'imprpssed on your mind, you will per.

garled in urine. are first, the circ,imslan'
