1the characteristic changes in the structures, formed by the aggregation of cells, must be caused by some alteration in the second factor—their mutual adhesion.
3The explanation of the observed phenomena can no longer be doubtful:—The movements of the individual fibres, caused by the strains set up by the alternate wetting and drying, must have, to some extent, modified or destroyed their mutual adhesion; by constant repetition they have acquired accommodation to the requirements of their environment, the friction of their surfaces in contact has become lessened by repeated strain or movement, they slip one on the other to the required extent.
5In the case of ropes which are repeatedly subjected to complete immersion and saturation, a part of the agglutinant may have been removed by the solvent action of water; this cannot be the case with wood which is subjected only to continual changes in the hygroscopic condition of the atmosphere.
7The seasoning, in the case of ropes or of pieces of wood (such as oars) which are alternately completely saturated, then partially or completely dried, will be quite different (in degree) from that of wood under shelter, exposed only to atmospheric changes. The seasoning or immunity from change of form will apply only within the limits of moisture and desiccation to which the fibrous structure has become accustomed.
9If, then, the slow movements, arising from strains which are set up in wood by changes of hygroscopic conditions, are capable of gradually loosening the adhesion of the fibres to each other to a small extent, it may be expected that continual vibrations, more or
