Incomplete triple phosphates (see Fig. 35) are seen in many forms andsizes. It seems that these crystals are in part not yet fully developed(especially the smaller varieties, which may in time grow and become.

The crystals may be broken down in the centre, orthere may be peculiar cross-like formations, or even irregular star-shapedcrystals, which can be likened to a fern leaf. Triple phosphates may be found in varying numbers in normal urineafter a vegetable diet. Their amount is increased in chronic inflamma-tory conditions of all kinds, in rheumatic processes, in inflammation ofthe bones, and in diseases of the nerve-centres. They are especially abun-dan
