- Summary:
- Washington presents new values for the specific gravity of an andesite at Laupahoehoe and an olivine basalt from Kaula gulch. He calculates a new average specific gravity for samples of Mauna Kea lavas (2.969), much higher than the value used by E.D. Preston (1894). He also gives densities of rocks from Haleakala and calculates an average density for that mountain. [Modern study questions the meaning attached to any average calculated from a few rock samples as representing the whole and also rejects the notion that there is a simple relation between the gravitational attraction of one body of known density and the density of the Earth.]
