section 37


Item if the urine be of the colour called cyanose,419 which is a composite colour of white, black, and red along


with fatty corpuscles, that signifies an ulcer in the bladder arising from an imposthume therein. If there be red sand in it, that shows the kidneys420 are not sound; sometimes this sand comes from the burning of sanguine humour in the veins, and then the urine is high-coloured: if it come from the kidneys it is not high-coloured, but whitish, being drawn from them before it is digested: in this way the sand results from the burning of blood,421 and is soft; at other times it signifies a stone in the kidneys, and is not soft, but hard, as is generally clear in the matter of stone.
