Latrodectus Mactans
PREPARATION.--The spiders are triturated in the usual way.
(The following paper by Dr. Samuel A. Jones appeared in
the Homoeopathic Recorder, July, 1889, under the
title, "Latrodectus Mactans: a Suggested Remedy in Angina
Pectoris"):
"The great result of the grim doctor's labor, so far as
known to the public, was a certain preparation or extract
of cobwebs, which, out of a great abundance of material,
he was able to produce in any desirable quantity, and by
the administration of which he professed to cure diseases
of the inflammatory class, and to work very wonderful
effects upon the human system."--Dr. Grimshawe's
Secret.
I do not know that the doctor who is the direct occasion of this paper
was grim, nor do I imagine he ever dreamed of such an application of
his paper as I purpose to make. I never met him; though he wore the gray
and I the blue during a struggle wherein fate might easily have thrown
us together. It was not until the autumn of '76 that I became aware of
his existence, and then by a contribution of his to a medical
magazine--the special copy of which was found amongst the multifarious
waifs of a bookstall. I could not "decline the article," although I was
then entering upon a field of labor that would leave little time for
such quiet research as the old doctor's paper so powerfully suggested,
so I bought the odd number, and fourteen years later I am making such
use of it as my sense of its significance enforces.
It is due Mr. A. J. Tafel to state that but for his most efficient
services this paper of mine would never have been written. To his
endeavors, stretching through some years, I owe the identification of
the remedy, without which I should not have put pen to paper; and having
secured this, from unimpeachable authority, too, he never rested from
his labors until he had put in my possession dilutions of the poison
itself. If, then, this magis venenum shall prove itself magis
remedium, most assuredly the pars magna of its introduction is his.
From the days of Dioscorides and Pliny to the present a venomous quality
has been ascribed to "the fluid emitted from the orifice in the fangs of
the arancidae." That this quality was even lethal has been both believed
and questioned. Insect Life, Vol. I., No. 7, pp. 204-211, Washington,
1889, contains "A Contribution to the Literature of Fatal Spider Bites,"
in which the credulity of mere medical observers and the emphatic
incredulity of professed "entomologists and arachnologists" are dwelt
upon, and concerning which its author cautiously concludes as follows:
"It will possibly appear to the reader that after collecting this
testimony we are as far from the solution of the question--'Do spider
bites ever produce fatal results?'--as we were before; but it seems to
us, after analyzing the evidence, that it must at least be admitted that
certain spiders of the genus Latrodectus have the power to inflict
poisonous bites which may (probably exceptionally and depending upon
exceptional conditions) bring about the death of a human being.
Admitting in its fullest force the argument that in reported cases the
spider has seldom if ever been seen by a reliable observer to inflict
the wound, we consider that the fact that species of the Latrodectus,
occurring in such widely distant localities as South Europe, the
Southern United States, and New Zealand, are uniformly set aside by the
natives as poisonous species, when there is nothing especially dangerous
in their appearance, is the strongest argument for believing that these
statements have some verification in fact. It is no wonder that a
popular fear should follow the ferocious-looking spiders of the family
Theraphosoidae; but considering the comparatively small size and modest
coloring of the species of Latrodectus so wide-spread a prejudice,
occurring in so many distinct localities, must be well founded." P. 211.
Is it indeed an argument that "in reported cases the spider has seldom
if ever been seen by a reliable observer to inflict the wound?" How an
Orfila, a Christison, and a Caspar would smile when asked if the
evidence of a poisonous quality depended upon the administration of the
poison being "seen by a reliable observer." Toxicology detects a poison
by the physiological test as well as the chemical. Strychnia in quantity
too small for the coarse chemical test is revealed by the tetanized
muscles of a frog whether that "arch martyr to science" be in "South
Europe, the Southern United States, or New Zealand," and that
infinitesimal fractions of Strychnia will display its characteristics
whether or not its administration is "seen" by a Christison, or a
college janitor. Of course, a Christison would recognize Strychnia from
and in the phenomena, while a college janitor (and here and there an
over-scientific entomologist) might not.
It is neither the aim nor the purpose of this paper to establish the
lethal property of spider poison; though I must acknowledge that, until
I read the paper in Insect Life, I had no thought that its possession
of such a property would be called in question. I shall content myself
with calling attention to the pathogenetic quality of the poison of
Latrodectus mactans, leaving my reader to discern the resemblance of
its tout ensemble to an attack of angina pectoris, and therefore to
infer its homoeopathic applicability in that dread disorder. I shall
not enter upon the pathology--various and much confused--of that cardiac
seizure, because, as I get older, I find the "like" more and more of a
"pillar of cloud by day and pillar of fire by night," whilst in my short
life I have found "pathology" as changeable as a dying dolphin--and
every one knows that a dead fish "stinks and shines, and shines and
stinks."
