50 TEXAS NATURE OBSERVATIONS AND REMINISCENCES.
has no relationship with the wide-
spread and common tapeworm
pest, the taenia medioconellata
and solium, it is a parasitic disease
sui generis as far as the Texas
jackrabbit is concerned. The par-
asite, therefore, does not produce
any tapeworm in man, as some
persons are led to believe, and
good cooking and frying will de-
stroy the fins or cysts in the meat
of any rabbit: but, of course, it
is better that such infected rabbit
meat should not be used at all.
In order to hear the opinion of
other professional gentlemen on
DR. FERDINAND HERFF.
Late Veteran Physician and Surgeon of San
Antonio, and Nestor of the Medical Fraternity
of Western Texas. (From life size and life
the subject, I addressed some
years ago, a few lines to Dr. F.
Herff, (who by the way, has had
an immense amount of practical
experience in this line, also), and
the venerable old gentleman kind-
ly forwarded me the following re-
ply on the subject: "The taenia
echinococcus is a very small tape-
worm with well-developed head
(scolex) and three or four joints
(proglottides). It lives in the in-
testines of the dog, and is not so
very easy to find and the rundish
appearance of the body, which at
first sight looks like a small nem-
atoid worm. Only by examining
it in water, by which the intestinal
mucus is washed away, and with
a common loupe you can disclos-,
its true organization. I stumble .
on it during the examination I
made on a dog which I had fed
with trichinotic sausage, while
hunting for intestinal trichinae.
Afterwards I found it many times
in the intestines of many dogs
which were killed by the police
during the rabies scare aand fur-
nished by DI)r. Petterson, thnu city
physician (in 1873). he emilbryon-
ic state in the rabbit ha;s beon
known to me long ago, as it is also
to many hunters who have shot
rabbits, and. in consequence, ere-
ated a disgust in people to e(at
them. The embryo liv yes il the
peritoneum and between the mIus-
cles in the connective tissues, and
is a true eehinioes---that
is, a scolex-which multiplies in
its cystic surroundings by slrCoult-
ing or budding , nl. e atingi new
scolices. In that respect it lifers
from cysticercus, which lives in a
solitary cyst, and to which fTmily
the taenia solium, medineanellate,
etc., belong, while the botrioceph-
alus latus develops free in water
at first, but probably euteirs then
a host (cistern, sink or waterpool)
and then is developed in the Ihdy
of man, as botriocephalus. These
of course, will not cause to
man, much less ech iunococus
which is only produced by iii., in-
gestion of the eggs of the mature
animal, the taenia eehin eoccus
which came from the dog that had
eaten infected meat from rabbits,
or through wolves or foxes who
also harbor the mature parasite.
Insofar the eating of infected rab-
bit meat is only disgusting, but
will not produce taenie. rPThe dog
however, is the evil-doer, and so
the fondling and kissing of lap-
dogs or the sleeping in the same
room with dogs is to Iie
avoided. * * *
