TEXAS NATURE OBSERVATIONS AND REMINISCENCES. 51
in man twice in the liver (in one
case over two quarts and one
quart in the other case); between
the extensors of the thigh; one in
the bulbus of an eye extirpated
for panonhthalmitis; once it
passed from the bowels of a lady
who had often suffered from pain
in the liver, but did not show any
tumor. My son took a great many
echinococcus from the bladder of
a child; they were large, trans-
parent and elongated. All these
specimens I mentioned contained
booklets, and so the diagnosis was
correct. I understand that Dr.
McLaughlin, in Austin, also re-
moved echinococci from the vagi-
no-rectal cellular tissue. I am sure
if proper inquiries were made it
would prove to be so. The speci-
mens of which you send the photo-
graph is a true echinococcus, as
the multiplicity of the heads in-
Besides above, I have a few
other communications on cases of
echinococci in man, including one
of Dr. R. II. L. Bibb, of Saltillo,
Mexico, stating that he had re-
moved a cystic tumor several
years ago, situated iii the cellular
tissue between the "trapezius"
and the "latissimus dorsi" mus-
cles, which the microscope showed
to be due to this parasite.
The microscopic mountings
which I prepared from specimens
of diseased rabbits, I may state,
were examined by friends with
much interest, especially also in
the private bacteriological labora-
tory of Dr. Julius Braunnagel.
After above had been written,
an additional paper on the sub-
ject heading this article was con-
tributed to the Texas Medical
Journal, and I herewith submit the
main part of same:
These investigations will show
that after the development of the
premature or embryonic p; rasite
of the echindcoccus tapeworm
from the ingested ova of the ma-
ture taenia, up to the migration,
encystment, and sprouting of new
embryonic colonies inside the
cyst membrane in different parts
or organs of the human and ani-
mal system, that all of these par-
asites in their most primitive sta-
dia already show quite a well-
developed head with characteristic
suckers and hooklets and after
further development, free them-
selves from the endocystic mem-
brane, although still adherent to
its linings and ultimately, after
still further r development, some of
the more mature of these embry-
onic parasites isolate themselves
later and free themselves entirely
from the other more premature
crop, and can then be found in a
free state either near the base of
the endocystic membrane or in-
side of the cyst fluid.
Something About the Texas Prairie Spider.
In his ramblings about the
prairie-plains, river-bottoms and
forests, the hunter and lover of
nature encounters a large variety
of interesting arachnids, from the
smallest, hardly visible spinning-
variety up to the iand-large black
or brown-colored and fearful look-
ing jumpingg tarantula.
With its immense area of over
274,000 square miles and sunny
clime, Texas naturally harbors a
large variety of spiders of differ-
ent type and colors; and, al-
though the more dangerous types
are not as numerous as encoun-
tered in the tropical zones of oth-
er countries, we have among the
smaller variety of interesting
arachnids some very vicious speci-
mens; and among these the small
speckled vagabond or jumping
tarantula is most conspicuous.
For reason of a lecture before
the San Antonio Scientific So-
ciety, the writer had the pleasure
