An adiabatic calorimeter was used to measure the heat of wetting of annealed and unannealed wool. Prior to wetting, the samples were adjusted to various water contents. From the curve relating heat of wetting and water content, differ ential beats of wetting were computed. It is concluded that annealing treatments cause changes no greater than 1 cal/g in the heat of wetting, and that the calculated results for differential heat as a function of water content are in fair agree ment with values that have been derived from a synthesis of previous work.
