Nine books of physick and chirurgery written by that great and learned physitian, Dr Sennertus. The first five being his Institutions of the whole body of physick: the other four of fevers and agues: with their differences, signs, and cures.

CHAP. VI. Of the causes of an oyly Vrine, and of other differences.

O Leaginous Urines either have only fat swimming in the superficies, * 1.1 or represent Oyl in substance and colour: the first difference proceeds from a melting of the fat, and is rather to be referred to the differences in the Contents; but that Vrine which seems like Oyl in substance and colour, and yet is nor truly fat, hath its beginning from the mixture of ex∣crementitious humours, especially of pale and black Choller, as also of Flegm, from whence proceeds a crudity with a certain greenness like Oyl; * 1.2 but when the difference in substance and colour are joined, a black Urine cannot be thin, but if the black humor makes it black, it is necessary that there is so great plenty thereof mixt with the Vrine, that the Vrine must be∣come thick.

A light red Vrine is thin from the small portion of blood mingled therewith, * 1.3 but if it be made of a pale red, 'tis by choller which cannot happen unless there be so great plenty thereof, as may render the Vrine thick.

A pale and thin Vrine is made when a small portion of chol∣ler is mingled with an aqueous Urine, * 1.4 but a pale red and thick, when choller is mixt in greater plenty, but if any choller be mingled with a thick white Vrine, the Vrine is dyed pale.
