Thepresence of phosphoric acid can be demon-strated by the ordinary reagents. Phosphate of lime dissolves in strong acidswithout effervescence. The presence of lime,as well as of phosphoric acid, can easily beverified by the usual tests. Oxalate of lime. The principal crystallineforms of oxalate of lime, when it occurs as aurinary deposit, are the octahedral and thedumb-bell. Of these the most common is theoctahedral. These octahedra (which haveone axis much shorter than the other two)vary considerably in size, but there is reasonto believe that the diversity in appearancewhich they exhibit is due to crystals of pre-cisely the same shape occupying difierent URINE 1701 positions as to the direction of their axes, ] are a great many diversities o£ the dnmh-bellwhen examined by the microscope.
