distinctive colours
Difficulties
to be surmounted
There is also no difficulty in making any
number of the minutest injections of a
more useful character, (when a suitable apparatus
for the purpose is used) which will demonstrate
the course and <s>distribution<\s> peculiarities of each particular set
of blood-vessels, and in which each set of blood-vessels
may be kept distinct, so as to be readily recognized,
by causing them each to be filled with a different
coloured fluid; but the real difficulty consists
in afterwards preserving preparations, made in
this manner, and in making microscopical
objects from them, which would <s>afterwards<\s> at a
future period, exhibit the anatomical facts in
a clear and decisive manner - The size, which
is used in these injections, continues for a consi=
=derable time to exude from the vessels and to
infiltrate the tissue, causing at first a cloudiness
and afterwards an opacity, which prevents the
minuter capillaries from being distinguished.
This opacity sometimes remains for months, but
becomes at length <s>[text?]<\s> redissolved -
Frequently however the preparations <s>for?<\s> are destroyed
by efforts made with a view to hasten this process
