AS the structures of the body are being more and more carefully investigated it is found that organs are composed of like structural units, which when repeated a number of times form the whole organ.In general these units are formed by the glandular structures, the blood-vessels, or by both, as is the case in the liver.Some eight years ago, at the suggestion of Dr. Mall, I undertook the study of the prostate gland, with the hope of finding structural units in it.Since then my work has been continued in the laboratories of Professor Born' of Breslau and Professor Spalteholz ' of Leipzig, and although this communication is several years late in appearing, it should in reality have preceded those that were published in 1899.I n the present study for the most part the prostate glands of dogs were used.Several cadavers were injected and the gross blood supply was studied in part from these.After the animals had been killed by chloroform, the aorta was exposed just above the bifurcation and injected with various substances.A preliminary washing out of the blood-vessels with salt solution was practised in a few of the first injections, but this was soon discarded as it did not seem to enhance the value of the method.Carmine gelatine, followed by ultramarine-blue gelatine, as an injecting mass, gave the most satisfactory results.About 250 cc. of the carmine gelatine were injected first, the injection being stopped as soon as all of the tissues had acquired a maximum carmine hue.This was followed by the injection of ultramarine-blue gelatine, which was kept up until no more of the material would pass in.The carmine gelatine I n this search I was successful.
