132 FIBRES though cellulose is, however, practically unaffected by the ordinary solvents, water, alcohol, ether, benzol, and weak solutions of acids and alkalies even at high temperatures, yet under certain circumstances its physical qualities of strength and elasticity may be very seriously damaged with out any appearance of chemical change. Strong solutions of acids and alkalies, especially if aided with heat, act upon cellulose by first swelling up the fibres ; this is followed Name of Fibre Source. Local it y. Remarks. I.
