Not illustrated. 1898 edition. Excerpt: ... in it (sediments, epithelial cells, leucocytes, &c.); when such mucoid coagula are ribbon-like in shape they often display a distant resemblance to tube-casts. The addition of a little dilute acetic acid makes the mucous substance much more distinct. Agglutination of pus-cells by a mucoid material gives rise to thread-like structures (Gonorrhceathreads). 2. Leucocytes in small numbers exist normally in mucus. Under the microscope they may be mistaken for epithelial cells, but are distinguishable from the latter by means of the glycogen-reaction, i.e. the mahogany-brown tinge they strike with solution of iodine in potassium iodide. They are present in larger numbers as a constituent of the pus in purulent cystitis, pyelitis, and urethritis, when they may form a yellow sediment. In acid or neutral urine their form is well preserved, but in alkaline urine (rendered alkaline by fermentation), they become swollen up by the ammonia into a shapeless slimy mass (often while still within the bladder), the microscopic examination of which reveals only detritus and free nuclei. On inverting the vessel the whole of the pus often falls out as a tenacious slimy mass. Donnifs test for pus depends on this behaviour. The urine is poured away as completely as possible, a scrap of caustic potash thrown in amongst the sediment and stirred up with it. The pus-corpuscles are changed into the above-mentioned tough, slimy mass. Vitali's test for pus is based on the behaviour of guaiacum resin, already described on p. 26. A few of sediment, acidified if necessary, are covered with a stratum of guaiacum tincture; after a short time the well-known blue colour makes its appearance. The examination for albumen enables one to decide the more
