LOCATION OF THE ECHINOCOCCUS. 
M. Legrand says, Echinococci have been found in the 
following organs: in the brain; in the lungs; in the liver; 
in the spleen; between the layers of the omentum; in the 
eye, between the crystalline lens and the choroid; in the 
urine and in the kidneys ; in the subclavicular cellular tissue; 
between the two layers of the tendons of the external 
oblique; and in the muscular tissue of the trapezius, and 
between the temporal muscle and the occipito-frontalis 
fascia . 55 
TREATMENT OF TRAUMATIC TETANUS BY APPLICATION 
OF ICE TO THE SPINE. 
Dr. B. B. Carpenter, of Suffolk County, New York, 
states that in 1833 he published two cases of traumatic 
tetanus successfully treated by ice, and that since that time 
he has similarly treated fourteen cases with a like result, except 
in one instance. His cases occurred in persons of good con¬ 
stitution and temperate habits. As specimens of the results 
of his treatment in the sixteen cases, he now publishes two 
examples, one of the acute and the other of chronic form of 
traumatic tetanus. It is a common and fatal disease during 
the warm months in the part of the country where he lives.—

MULTIPLICATION OF SPECIES. 
There is no exception to the rule, that every organic 
being naturally increases at so high a rate that, if not 
destroyed, the earth would soon be covered by the progeny 
of a single pair. Even slow-breeding man has doubled in 
twenty-five years, and at this rate, in a few thousand years, 
there would literally not be standing-room for his progen}^ 
Linnaeus has calculated that if an annual plant produced 
only two seeds—and there is no plant so unproductive as 
this—and their seedlings next year produced two, and so on, 
then in twenty years there would be a million plants. The 
elephant is reckoned to be the slowest breeder of all known 
animals, and I have taken some pains to estimate its probable 
minimum rate of natural increase ; it will be under the mark 
to assume that it breeds when thirty years old, and goes on 
breeding till ninety years old, bringing forth three pair of 
young in this interval; if this be so, at the end of the fifth cen¬ 
tury there would be alive fifteen million elephants descended 
from the first pair .—'On the Origin of Sjpecies/ by C, Darwin .
