Beare, Sir Thomas
Sir,-I think Mr. Gray is hardly fair to the theory of the water-cement ratio. Professor
Abrams only tries to deal with one variable at a time; and his statement is that, other
from remaining unaltered, the lower the water-cement ratio, the higher the strengthas
long as the mixture remains workable. He stresses the qualification, to which he attributes the downward droop of the curve at low ratios. The qualification has had results of practical value in leading to the development of vibrating machines.
Mr. C. J. JACKAMAN proposed a hearty vote of thanks to Mr. Mears, and commented upon the Institution’s good fortune in having secured a paper so novel in character.
THE writer left England on September 25 th, and, after a pleasant voyage, arrived at Montreal on October 3rd.
