Signs of the proper causes of dropsy, the which are not signs of the species. Dropsy produced by the stomach, the intestines, and the veins known as meseraic, is recognised by continued diarrhoea beforehand, having no colour of blood. When it comes from the liver, it is recognised by a hard cough and by the excess of the first digestion being hard.646 The dropsy that comes from an imposthume is known by the bloody colour of the flux: that from the spleen by the colour turning livid, or ashen, and preceded by pain in the spleen. When it proceeds from the reins, the appetite is strong,647 and there is pain and oppression round the kidneys, behind them, and just a very little above the belt of the trousers, or a little below it.
