ponding deflections. It will be observed that the loads 

 and deformations in Nos. 2, 3, and 4 are very similar, and 

 it was considered that the mean obtained would be more 

 useful. This has been done in Fig. V. f. and Table V. 

 The curves Fig. VI. a. and Fig. VI. c. all show very rapid 

 increases in extension for the gradually increasing loads 

 applied, and corresponding diminution in the coefficient 

 of elasticity of the reinforced concrete in tension. The 

 other diagrams show the same peculiarities, but to a lesser 

 extent. In the curves of loads and deflections, Fig. VI. d. 

 No. 2 a, show very small deflections up to a load of 3 tons, 

 the deflections then increase more rapidly up to the 

 breaking point. This change in the diagram is charac-
