Arsenal report for 1894 (p. 377) : "Micrometer observations were made under different loads, beginning with an initial load of 100 pounds per square inch. Permanent sets were determined at intervals, and the behavior of the stones noted while under reduced and repeated stresses. Stones have a variable modulus of elasticity, the rigidity generally increasing with the stresses. Plate XXIV-B shows the instrument used at...
