MACHER in 1893 and again by BANCROFT‘ in 1902 has been of the 
greatest service to physical chemistry, where both theoretical and 
practical consideration of eee composition of three component 
parts are concerned. 
In the present investigation we have likewise to consider the three 
component parts of the fertilizer mixture; namely P,O,, NH,, and

“K,O. It is possible, therefore, to represent any mixture of these 
three component parts in the triangular diagram. Such a triangular 
diagram is shown in fig. 1. It is an equilateral triangle in which the 
extreme points of the angles represent 100 per cent respectively of
