The difficulty is that the hygroscopic reaction is inconstant, rather than that the instruments are not sufficiently sensitive. A number of hygrometers have been tested, and in all the error has been found to be great, varying usually from 10-20 per cent. In the middle of the scale they sometimes read more accurately, but toward either extreme they are very inexact, It seems probable that an accurate hygrometer can be constructed only after the model of the Draper psychrograph.
