The animal extracts employed in our Institution are all scientifically
and carefully produced in our chemical laboratory under the direct
supervision of an experienced chemist, and are believed to be superior
in quality. They are turned out fresh, as wanted, which is important, as
all such preparations, no matter how carefully made and put up,
deteriorate with age.

These extracts are made from the glands and organs of the lower animals,
as from the brain, spinal cord, heart, testicles, ovaries and some other
organs and parts of bullocks, rabbits, guinea pigs and other animals.
That they possess properties which exert most potent tonic, or
invigorating, influences upon those organs and parts of the human system
corresponding to the organs and parts of the lower animals from which
they have been extracted, no longer admits of doubt. In cases of partial
and even complete impotency, especially in elderly men, attended with
nervous exhaustion, most astonishingly favorable results are obtained by
our specialists through the administration of our extracts obtained from
the nerve tissue of the spinal cord, associated with the use of the
expressed juices from animal testes. We do not, however, prescribe these
extracts to the exclusion of other well tested remedial agents, but do
regard them, especially in the more confirmed and obstinate cases, as
among our most positive curative agents.

We must confess that when first proclaimed by Brown-Sequard as Valuable
remedial agents, we regarded the use of these extracts with good deal of
skepticism, but experience is, after all, the best teacher and we were
forced, after numerous successful tests, to admit their great efficacy.
We have always endeavored to keep up with the vanguard of the army of
medical reform, and so took early occasion to introduce these agents
into our practice and made preparations to produce them in our
laboratory.

From an article written by an eminent specialist in nervous diseases,
and recently published in the New York _Medical Journal_, we extract the
following:

"Organic beings possess the power of assimilating from the
nutritious matters they absorb the p
