摘要：Some quantities of dry substance of milk, determined hy the method of drying at 102 °C and by estimating according to Fleischmann's formula of analyzing 94 samples, have been compared. By the statistical checking of obtained values using T-test, a very highly significant difference (p < 0,001) between the results of both methods has been found out. The quantities estimated according to FIeischmann's formula always have a big value (t = -8,15), so they can not be used for estimating of milk quality.
