. Urinary analysis and diagnosis by microscopical and chemical examination. Fig. 37.—Star-shaped Simple Phosphates (X 500). may have a uniform diameter or be broadened at the periphery and nar-rowed in the centre. Much has been written about the significance of the phosphates in theurine, and great stress has been laid upon their continual increase ordiminution, the latter being said to be of constant occurrence in cases ofnephritis. It is an undeniable fact that the phosphates are diminished 88 URINARY ANALYSIS AND DIAGNOSIS. in severe and usually advanced cases of nephritis, but not more so thanthe other salts, there being a pronounced decrease of all salts in such j cases. In rare cases there is a continual increase of the phosphates in theurine, without any apparent cause. Such cases have been designated bythe term phosphahiria, and they may give similar symptoms to those ofoxaluria. The phosphates precipitating in the urine being frequently.

A change of diet will often rectify this trouble ina short time. All phosphates are easily soluble in acetic acid, which willquickly clear up any doubts as to their character. 3. Ammonium Urate.—Ammonium urate is a common sediment inalkaline urine, especially in connection with triple and simple phosphates, and is seen in fresh urine only when it is passed in an alkaline condition.

It appears (see Fig. 38) in theform of brown globules of various shapes and sizes, usually exhibitingpronounced concentric and radiating striations. The globules may ap-pear singly or in clusters, sometimes forming large, coalesced masses.They are either smooth or
