the cuticle, which is destroyed
and removed in the process, partly by the chemical action of the alkali,
and partly by the stretching at one or other stage of the process. The
authors have investigated the action of alcoholic solutions of soda
also. The lustre effects are not obtained unless the action of water is
associated.

In conclusion, the authors give the following particulars of breaking
strains and elasticity:--
