Deidre felt the **wetness** of her tears.

Her eyes grew blurry, and hot **wetness** slid down her cheeks.

Schimperl made a distinct advance when he distinguished between physical and physiological dryness or **wetness** of the soil.

Habitats of medium **wetness**, with the accompanying plant communities of woodlands and grasslands.

Related to the physiological drought, such plants possess some xerophytic characters; and, related to the physical **wetness**, the plants possess the aeration channels.

For this reason observations at different depths in the same locality often give very concordant results for the same period, as the total percolation and the average rate are necessarily nearly the same for the various strata, although the actual degree of **wetness** of each may vary considerably.

It was first employed in the case of steam by Peabody as a means of estimating the **wetness** of saturated steam, which is an important factor in testing the performance of an engine.

It is evident that this is a very delicate method of determining the **wetness** z, but, since with dry saturated steam at low pressures this formula always gives negative values of the **wetness**, it is clear that Regnault's numerical coefficients must be wrong.

The mean value, 0.313 of dH/d0, between loo° and 200° agrees fairly well with Regnault's coefficient 0.305, but it is clear that considerable errors in calculating the **wetness** of steam or the amount of cylinder condensation would result from assuming this important coefficient to be constant.

All soils which are physically dry are also physiologically dry; and hence only the physiological dryness or **wetness** of soils need be considered in ecology.
