    They were of the figure of a rhombus, whose opposite angles are obtuse and equal; other parallelopipcd molecules ran between them, redder and larger than the former. Some square grains were also seen between them, but very few. It was never observed, in these experiments, that molecules con- creted in the urinary cloud as large as those formed on the sides and bottom of the cy- linder that contained the urine. It appeared, also, that these rhomboidal molecules here and there affixed themselves to each other by the sides, so as to become of a larger size, from six such corpuscles being mutually attached to each other. From this experiment the Professor con- cluded the stone to be produced by granu- lation or crystallization, not from different elements in the body, or from a confused mixture of concreting humours, as others maintained, but by the approximation and application of like elements. Dr. Clerk having observed certain fila- ments often flowing in the urine, which, though less transparent than the urine, were, nevertheless, when taken out, found to be pellucid as crystal, thought them to be the cause of the gout and stone; because, when dried, they became a whitish calx, lie sup- posed it to be the vitreous pituita of the an- tients. Galen describes himself to have been relieved by the voiding abundance of a vi- treous pituita from a violent pain, the cause of which he had attributed to a stone de-
