erroneous. In this way great injury is inflicted
upon the reputation of the profession, as well as
those who are afflicted with disease.
If there is one man in society who should be at-
tentive, cautious and careful, that man is the phy-
sician. To a certain extent the health and life of
the community are in his hands. One mis-step on
his part may break the golden cord on which is
suspended the earthly existence of a fellow being.
It is a fearful reflection that he deals in deadly in-
struments, and that when he wields them without

proper care and discrimination he may kill his
friends as well as his foes. A careless physician
is a dangerous man in the comnyinity. I would
rather live near a volcano than such a doctor. He
should not be tolerated in the ranks of the regular
profession. Turn him over to Homoeopathy, so
that if he will continue to prescribe for the sick
without forming a correct diagnosis of their dis-
orders, he may give them medicine in such infini-
tesimal doses that it will not do them any harm.

DEFECTIVE AND IMPAIRED VISION.

With the Clinical use of the Ophthalmoscope in
their Diagnosis and Treatment.
By Laurence Turnbull, M. D.,
Ophthalmic Surgeon to Howard Hospital, &c.
The Ophthalmoscope—Directions as to its Em-
ployment. (Continued from p. 307.)

Before commencing with directions for its man-
agement, I ought to mention that the ophthalmo-
scope, when employed alone, gives the upright
picture of the interior of the eye, but when we use
the lens we see an inverted picture, so that
what appears to be placed upward or inward, is
in reality situated downward and outward, and
vice versa, the great advantage derived from the
use of the double convex lens is that by it we ob-
tain a larger picture ; but should we desire to
reduce it we then can use a double concave lens.
The simple mirror of Anagnostakis, used in com-
bination with a convex glass in the manner I am
about to describe, certainly allows of our seeing in
their real position parts which do not fall within
the focus of the patient's crystalline lens. Thus a
morbid growth — an encephaloid mass, for instance
— which might be seen on the floor of the vitreous
chamber, would be found really to occupy that po

sition when the globe has been extirpated.
