sure, weight and crowding may do very serious injury and make
the flow of semen irregular, or shut it off altogether.}

Fluid_ of a strong, robust man.

And is it surprising that the continual losses do drain away strength
and vitality? This fluid is the only one charged with _life_--actual
_life_; capable of producing _life_--of creating offspring--of
impregnating and developing into perfect being, with thinking and
reasoning brain and mind, pulsating heart, expanding lungs, sentient
nerves, motive muscle, and all that beautiful, minute and co-ordinate
mechanism that forms a perfect human being--the only secretion in the
body capable of propagating species--carrying _life_ within _life_.

Surely this was not meant for waste. Surely the influence of its loss
upon the system, especially of a boy or young man (growing and not fully
developed), must be great, and it is. Many and many a young man thus
wastes away before the eyes of his friends from no other cause. Many a
one loses health and strength from this cause alone, yet does not know
it. How much better if all this false modesty, social hypocrisy, and
blundering medical dosing and drugging, without thorough examination and
full understanding, were wholly done away with, and the young men, and
old men too, were brought to understand two cardinal facts:

(a) The immense devitalizing effects of even small continued losses of
vital fluid, and,

(b) The fact that many apparently strong and healthy, as well as weak
and nerveless, men who find their sexual powers gradually or suddenly
failing them, can, in nine cases out of ten, trace it directly to
losses of vital fluid in the urine or otherwise, that have been going
on--perhaps wholly unknown to them--for months or years past.

ANALYSIS OF URINE.

At the first symptom of Sexual Decay or Nervous Exhaustion, the person
thus affected should have his urine carefully and thoroughly analyzed by
some competent person. In saying "competent person," we speak advisedly,
for but few chemists and fewer physicians are competent to make such
an examination and draw correct deductions from what is to be found
there. Any person can, with the proper
