Abstract
American Journal of Science, September.—Transition temperature of sodic sulphate, a new fixed point in thermometry, by T. W. Richards. Sodium sulphate, Na2SO4 + 10H2O, “melts” at almost exactly 32˙48° according to the mean mercury thermometer, and this temperature is so easily obtained by means of that salt and so constant as to be of great use in the future for thermometric and thermostatic purposes.—
