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
