Deductions from smooth rocks
Extract from Bettie Higgs's reading of rocks in 'Visual Practices Across the University'. Most of the rocks in this photograph are about 360 million years old, so the grains that comprise them are substantially older. The grains came originally from a mountain range, as large as the Himalayas, whose roots can still be seen in counties Mayo and Donegal, in the northwest of Ireland. The grains were carried south by rivers and deposited in this area; the smallest grains were carried all the way to the ocean, which was far south of Cork at the time, in what is now the Atlantic Ocean south of Ireland. (There was very little rainfall at the time: the portion of land that is now Cork was 10° south of the Equator. This can be deduced from the properties of the iron in the rock.) The water in which the grains were transported was oxygenated, and the iron precipitated out as iron oxide (haematite), which cemented the grains and which accounts for the red color (Elkins 2007: 74 - 78). -
Zinc Sulphate
"Astringent. One or two dissolved in an ounce of water, will be found useful as an eye-lotion, and as an injection or astringent lotion" (BWC 1925:144). -
Phenacetin
"One to two, powdered, and taken, if possible, in a hot liquid, will be found useful in headache, neuralgia, etc. The dose may be repeated after an interval of three hours" (BWC 1925:134). -
Opium
"Anodyne, astringent, narcotic. Use with caution. In cholera and dysentery, one to two may be taken with a little water, by an adult, according to the symptoms of the case. For the relief of pain, one my be taken every three or four hours until desired effect is obtained" (BWC 1925:133).
