same role in the filtration of the gastric contents,
as tgg albumen in the preparation and filtration of
broth cultures.
6. Specimens of gastric contents positive for
blood were examined immediately after removal and
the intensity of the reaction noted. These were
then allowed to stand for three.to six hours. At the
end of this time the upper, clearer portion and the
sediment were examined separately. It was found
that the former was either negative or only faintly
positive for blood, while the latter gave a stronger
reaction than the freshly mixed contents. This is
due to the Purchase Oxybutynin Online fact that the blood Order Oxybutynin exists in the form of
hematin granules, which by reason of their high spe-
cific gravity and their tendency to adhere to other
particles, rapidly gravitate to the bottom of the glass.
This obviously is of considerable practical import-
ance; for if the upper portion of such a specimen is
poured off and employed for the blood test, almost
the same negative results will be obtained as with
the filtrate.
Certain factors influence the contrast which ex-
ists between the filtrate and unfiltered contents. The
sooner the filtration after Order Ditropan Online removal and the greater
the amount of blood in the unfiltered contents, the
less the contrast. The greater the amoimt of par-
ticles in suspension, and the more thorough the
process of filtration, the greater the contrast be-
tween the filtrate and unfiltered contents in their
behavior to occult blood tests.
All these observations have been made sufficiently
often to show that they are constant. They show
clearly that examinations of the filtrate are unreliable
in determining the presence of occult blood in the
gastric contents. The mixed unfiltered contents or, if
the test is to be more sensitive, the sediment after
standing or centrifuging should be employed. This
fact is not generally recognized : for in the leading Buy Cheap Ditropan
textbooks on gastrointestinal diseases instructions
are given to employ the filtrate for the test.

FILING CONVENIENCES SUITABLE
FOR PHYSICIANS.
By J. Madison Taylor, M. D.,
Philadelphia.
The man in active practice has need for con-
venient and systematic means for filing Cheap Ditropan at least a
dozen varieties of data of written or printed ma-
terials. Among them are the following: 1. Short
notes on cases, on the casual client ; to Purchase Oxybutynin jot down
the name, address, complaint and primary advice
given. 2. Generic Oxybutynin Fuller notes on progressive cases. 3.
Associated data, correspondence about cases, etc. 4.
Business correspondence. 5. Reprints of medical
and scientific papers. 6. Useful data from adver-
tisers, objects, instruments, materials and drugs,
especially working bulletins of new products and
scientific researches of the manufacturing houses,
as advocated by Dr. Francis E. Stewart. 7. Hos-
pitals, sanatoria, special schools for mental defec-
tives, convalescent homes, summer camps for boys
and girls and others. 8. Climatic data, reports, trans-
portation, miscellaneous. 9. Small card index for
books Buy Ditropan ; a, books in one's own library ; b, Buy Cheap Oxybutynin books de-
sirable to read at some time. Differentiate by colors
of cards, or better by colors and separate drawers.
It is also desirable that any or all of these refer-
ence data should be readily accessible, in reach of
his office chair.
In pursuance Purchase Ditropan of an earlier enterprise which im-
pressed Purchase Ditropan Online me with its importance, I wrote a series of
letters to the editor of Journal of the American
Medical Association, beginning about twenty-five
years ago, offering suggestions to the great manu-
facturing houses, the purveyors of useful objects,
drugs and other materials, urging that they Generic Ditropan adopt a
uniformity in the size and shape of their printed
matter, in particular Order Oxybutynin Online that they use the standard
three by five inch index filing card, for business
summaries, cards or small booklets.
These recommendations were at once adopted by
certain manufacturing houses and now most of the
large drug firms are following suit. Later I urged
that the leading medical journals agree upon a uni-
form size and Buy Oxybutynin shape of their fuller data. So far Buy Ditropan Online no
attention has been given to the hint. They must
come to it ; the sooner the better. A recent com- Oxybutynin Online
munication elicited attention from some of the drug
houses and I was asked to offer specific recom-
mendations. After consulting the makers of filing
cabinets I Buy Oxybutynin Online learn that it is entirely practicable to use
certain standard cases. These being adjustable, any
one being able to adopt some one or Order Ditropan more parts. I
offer the following idea.
A filing cabinet of standard qualities can be as-
sembled to contain; 1, Ditropan Online one section of five filing
cases or drawers, each five by eight inches, hori-
zontally placed ; 2, one section, three drawers, nine
