TitlePaper, 'The physical properties of vulcanised India-rubber' by A [Arnulph] Mallock
Date1889
DescriptionMallock writes: 'Considering the wide use now made of india-rubber, it seems curious that the elastic constants which define its properties should not be as well known as the corresponding quantities for iron or brass. The only published quantitative measure, however, with which I am acquainted, relating to the subject, is contained in a paragraph of Thomson and Tait’s "Natural Philosophy" (p. 230, Part II, New Edition), where the resilience of vulcanised india-rubber, i. e., the amount of work restored by the substance when allowed to return to its equilibrium form, after having been stretched to a maximum short of rupture, is stated to be equivalent to its own weight raised through 1200 metres.'

Annotations in pencil and ink. Includes two pages of diagrams of experimental apparatus and results.
