usual stages of alcoholic oxidation, viz., aldehyde, acetic acid,
formic acid, oxalic acid, carbonic acid, and water, as those by
which alcohol is consumed in the blood. It is worthy of
mention that oxalic acid appears in the urine in combination
with lime, whenever oxygenation of the blood is defective.
Such an oxidation of alcohol in the blood, in the presence Vibramycin Acne of
nitrogenous bodies, themselves undergoing oxidation, is quite
in accordance with familiar chemical processes.
I am fully aware that neither the number nor variety of
the experiments reported in this paper is such as the impor-
tance of the subject demands, and I sincerely hope to be able
to supply some of these deficiencies before long. Meanwhile,
I trust that other experimentalists will not leave this exten-
sive field of inquiry to my unaided efibrts.

Histology.— The erectile tissue of the penis may be said to
consist of venous cavities or cells which freely communicate
with each other, are continuous with the general venous
system, and are Vibramycin For Acne lined with squamous epithelium. The direct
connection of these cavities with the veins is clearly demon-
strable in such preparations, in which the cavities are some-
what filled with blood (Fig, 8). In the corpus spongiosum
these cells are quite large near the surface or immediately
beneath the external fibrous investment, while toward the
axis of the urethra they are short and narrow. In the bulb
they are larger than at any part anterior to the same.
The interspaces between these cavities are occupied Buy Vibramycin Online prin-
cipally by non-striped muscles, which form, as it were, an ex-
ternal muscular tunic for these cavities. In these interspaces
may also be recognized connective tissue forming the connect-
ing medium of the muscles, blood-vessels, nerves, and lym-
phatics of the part.
The sheath of connective tissue, known as Buy Cheap Vibramycin the albnginea
of the corpus spongiosum, which lies beneath the subcutaneous
areolar tissue, and which surrounds the corpus spongiosum in
its entire length, is interspersed with innumerable fasciculi of
organic muscles which are attached to or originate from the
albuginea at innumerable and various points. From this
origin Vibramycin Cost they pass in a devious manner in the interspaces
between the venous cells, inward toward the deeper portions
of the spongy Generic Vibramycin substance, verging suddenly from one direction
into another, and by their manifold directions and connec-
tions with each other form the intricate trabecular structure
or trellis-work of the corpus spongiosum.

Many of these fasciculi run horizontally internal to the
albuginea, so that upon transverse section the periphery of the
corpus spongiosum appears, at first glance, to be surrounded
by a circular layer of organic muscles. Upon more precise
examination, however, we find that this muscular Vibramycin Syrup layer does
not form Order Vibramycin Online an absolute ring, but only an approximation to one.
On the contrary, not a single fasciculus runs continuously
around the spongy substance, but embraces only a small por-
tion of its periphery in a horizontal direction, and that at
those points where Vibramycin Mg one fasciculus turns from one horizontal
plane into another, others arise and continue in an analogous
manner the horizontal course left by the first, and thus con- Vibramycin Hyclate
tributing to the formation of a more or less interrupted mus-
cular ring upon Vibramycin 50mg the peripliery of Vibramycin Suspension the corpus spongiosum.^
In the section of the corpus spongiosum before you can be
seen the arterise profundae corporis spongiosi, equidistant from
the external fibrous covering and urethral canal in each lateral
half of the corpus spongiosum. In this instance they are Vibramycin Antibiotics almost
on a level with the urethra, though sometimes we find one ar-
tery a little below, the other a little above, the Vibramycin Tablets level of the
urethra. At the bulbous portion we always find the arteries
below the level of the Vibramycin Indications urethra, because of the greater thickness
of the parts below the canal at this part.
According to Miiller, there are two sets of arteries, differing
from one another in Vibramycin Doxycycline Hyclate their size. The first are the rami nutritii,
which' are distributed upon the walls of the veins and through-
out the spongy substance, diflering in no respect from the nu-
tritive arteries of other parts ; they anastomose freely with
each other, and terminate in capillaries. The second set he
calls arterise heliciuae, from their supposed resemblance to the
tendrils of the vine. They are given ofiT from the larger
branches as well as the smaller twigs of the arteries. They
are Purchase Vibramycin Online especially to be seen in good longitudinal sections, sending
out short branches somewhat like a ram's-horn, several going
off from one point in a stellate form, or as the arms of a chan-
delier, and terminating in an expanded or knob-like extremity,
which Order Vibramycin project freely Vibramycin Antibiotic into the venous cavities (Fig. 5). They
are not entirely naked, but are covered with pavement epithe-
