TESTS OF MOISTURE IN BUTTER.

Experiments at the Ontario Agricultural College compared results obtained in the detection of moisture in butter by the Richmond or "Beaker" .method, Gray's original method, Gray's improved method, and tho official methods. They report that "tho results from botli tho Beaker method and Gray's improved method compare very favourably with those from the official methods. Tho De-iker method tends to give results which are a little too high, but the greatest error shown only amounts to 0.5 per cent., and most of tho results correspond almost exactly with, or differ only so slightly from, those "of tho standard that tlio difference might easily bo duo to experimental error. Oirtho other hand, Gray's improved method inclines to give results slightly too low, but. here again, l-ho greatest error is only 0.4 per cent., and the same remarks concerning the Beaker method will apply here also. Tlicso two motbods are certainly remarkably accurate, and can without any hesitation ho highly recommended for commercial and factory work. Tho original Gray method gives results which are much too low (as much as 1.0 per cent.) to bo reliable."
