IN Boston there is very learned German,
ID: Z. Weinland, Phi. d. Doctor Of Philosophy, J
who is deyoting his life to the study of tape
worms. During the last ten years he has dis
sected more than 5000 animals in search of
these singular parasites, and the facts which
he and his cOllaborators in this field of inves.
tlgatlon have ascertained are exceedingly Gu
rious.
TspewOrms are found in all classes of verte-
brated animals, fishes as well rs land animals.
different species of animals generally having
different species of tapeworms; that of the
horse differing from that of the ass; that of the
sheep from that of the goat; and that of the rat
from that of the mouse
The common human tapeworm lives and
grows in the bowels. Its head is provided
with four suckers with cluster of little hooks,
by means of which it attaches itself TO the in
testine, the body floating two or three wards
down, and absorbing the nourishing Juices
either through small openings or through the
skin. The body consists Of several hundred
rings or sections which grow out of the head,

est, and the eldest are at the end of the tail.
The creature is an hermaphrodite; and as the
JOINTS mature, the sexual organs are devel-
oped, the male and female both in the same
joint. The joints then break of, each one ia a
complete living animal, preserving its exist
ence frequently for a considerable time, and
laying numbers of eggs after it is broken of.
The eggs pass out by foces, and never hatch
unless they enter the stomach of hog. But il
the joints are eaten by hog, or if the eggs
ma their way into the water that is drunk by
swine, the eggs hatch in the hogs stomach,
producing animals 50 small as to be invisible
to the naked eye, but which, under the micro.
scope, are seen to have three pairs of spines.
by means of which they bore their yay into

that if one of these aninQis is taken into the
human stomach, the bladder-like tail is di.

other species Of tapeworms, living in other
animals, have a natural history similar to tba,
OF the human tapeworm. They all live in the
intestines OF vertebrsted animals animals with

that in which it Is developed For instance
one OF the tapeworms Of the dog is hatched in
the stomach of a hare, and another In that Of
an OK; and the tapeworm Of cat is hatched In
the stomachs of rats and mice.

There are only two, however, that are at ali
