Book excerpt: Excerpt from Transactions of the Royal Society of Tropical Medicine and Hygiene, Vol. 5: April, 1912 I should like to say that the difficulty of demonstrating intestinal entamoebae, either in the living or fixed and stained condition, is much exaggerated. After a little practice it is impossible to miss them, and if thick slides, which have been dipped in hot water are used for fresh specimens, the movements of the organism can be readily followed in ordinary room temperatures for two. Or three hours. Except in very cold weather, a warm stage is unnecessary. As to stains, a modifi cation of romanowski is essential, since, for differentiation of species, nuclear staining is very important, and I find that one routine method for practically all specimens, viz., giemsa's original process, is the best. As you see, with its use one should not mistake either the nature of the organism or its contents. The red blood corpuscles, which in this Specimen are lying free in the blood-stained mucus in such quantities, take on an orange-red Shade, which they retain after they are englobed, although it gradually becomes paler and dingier as digestion goes on. One occasionally sees some debris and granular matter extruded by the living organism, but apparently the whole corpuscle, haemoglobin and all, is assimilated by Entamaeba histolytil'ca without difficulty and without refuse.
