An ingenious method has Just been de.
yised for actually observing the Circula-
ton Of the blood In man. Hitherto, ex.
eept in the case Of PutkinIe's experiment,
In which an observer can sec the circula.
ton in his own retinal blood vessels, the
evidence Of circulation in the human sub.
ject haa been entirely circumstant.al, De.
rived from the facts Of structure Of ctrcu.
latory organs, aud from the manner, in
which the blood flows from severed arter-
les and YeiEs. But by means OF simple
arrangement, invented by DR.. O. Huter,
Of Grietswald, II Is now possible to witness
the actual dow Of blood In the blood yes.
sci Of another person, and that with SUI.
ticient accuracy 10 detect any Abnormality
in the circulation, and so to obtain invat.
liable assistance In the diagnosis Of disease.
In DR., Huter's arrangement the pa.
TENTS head Is fixed In a frame something
like that used by photographers, on which
10 contTiyAnce Tor supporting micro.
scope and lamp. The lower lip Is drawn
out and fixed by means OF clips on the
stage Of the microscope, with It's inner sur.
face upward; strong light Is thrown on
this surface by condenser, and the mi.
croscope, provided with low.poYer OBJ.
jective, Is brought TO bear upon the deli
cate network OF vessels, which can be
seen in the position indicated, even with
the naked eye.
The appearance presented Is, at first, as
II the vessels were filed with red iniec-
ton. But by focusing a small superficial
vessel the observer Is soon able to distin.
guish tho movement Of the blood stream,
rendered evident by the specialize red
corpuseles, the flow Of which, in the cork
screw.ltke capillaries, Is said by Huter to
be especially beautiful. The colorleSs
corpuscles are dlstnguishable as minute
white specks, occurring now and again In
the course otthe red stream. Besides the
phenomena Of the circulation, the cells OF
payementepithelium lining the lip, and
their neuclei, can readily be distinguished
as well as the apertures Of the mucous
glands.
Besides the normal circulation, various
pathological conditions can be observed.
By a pressure quite sufficient to cause
pain, the phenomena Of blood stagna-
tion-the stoppage OF the flow, and
the gradual change in color OF
the blood from bright red to purple-are
seen. A momentRry stopping Is also pro-
duced by touching the lip with ice, a
more enduring stasis by certain reagents,
such as glycerine or ammonia.
Huter states that he has already proved
the great use Of "Cheiloangioscopy," as he
calls the new process, in bis medical prac-
tice. The variation in the blosd.How and
in the diameter Of the vessels, the crowd.
ing together Of the red corpuscles, the in
crease in number Of the white corpuscles,
occurring in certain diseases, all these may
be observed readily and exactly. 1t will,
indeed, be at once obvious how great is
the importance Of q method like this, BY
which an actual observation OF the circula-
ton Is made possible, especially when il
Is borne In mind that even the rough and
ready method Of feeling the pulse affords
q valuable indication Of the state ofhealth.
