More interesting is the account of a successful case of transfusion of
blood in the human subject, performed in presence of the ablest
surgeons of Paris. A woman was taken to the Hotel Dieu reduced by
hemorrhage to the last stage of weakness, unable to speak, to open her
eyes, or to draw back her tongue when put out. The basilic vein was
opened, and the point of a syringe, warmed to the proper temperature,
was introduced, charged with blood drawn from the same vein in the arm
of one of the assistants. The quantity, 180 grammes, was injected in
2-1/2 minutes, after which the wound was dressed, and the patient
placed in a comfortable position. Gradually, the beatings of the pulse
rose from 130 to 138, and became firmer; the action of the heart
increased in energy; the eyes opened with a look of intelligence; and
the tongue could be advanced and withdrawn with facility, and regained
its redness. On the following day, there was a little delirium, after
which the pulse fell to 90, the signs of vitality acquired strength,
and at the end of a week the woman left the hospital restored to
health. Cases of successful transfusion are so rare, that it is not
surprising the one here recorded should have excited attention among
our physiologists.

People inclined to corpulence may profit by M. Dancel's observations
on the development of fat. He says, that some of his patients, whose
obesity was a constant inconvenience and cause of disease, 'lost very
notably of their _embonpoint_ by a change in their alimentary
regimen--abstaining almost entirely from vegetables, feculent
substances, diminishing their quantity of drink, and increasing, when
necessary, their portion of meat.' On another, subject, M. Guerin
Meneville believes he has found a new cochineal insect (_Coccus fabae_)
on the common bean, which grows wild in the south of France, and in
such abundance, that a considerable quantity may be collected in a
short time. The yield of colouring matter is of such amount, that a
project is talked of for cultivating the plant extensively.

A communication has been made to the Geological Society at Paris by M.
de Hauslab, on a subject which has from time to time occupied the
thoughts of those who study the _physique_ of the planet on which we
live--namely, the origin of the present state of our globe, and its
crystal-like cleavage. After a few preliminary remarks about
mountains, rocks, dikes and their line of direction, he s
