This paper is intended to form the foundation of the theo- retical part of a series of researches on the strength of materials. tSir D. Brewster begged to suggest to Mr. Rankine that by an exami- nation of the action of transparent solids on polarized light, the correct- ness of these theoretic views might be tested or corrected: and so accurate and simple was this method found to be of testing the nature of the constraint under which the several elements of a strained body were, that models of' pieces of"earpentry were now actually constructed in glfiss, subjected to the kind of strain to which their representatives would be exposed; and the kind and degree at each part rigorously ascertained by polarized light.--/bid. On a New and Ready Process for the Quanlitalive Determination of Iron. By Dm F. Pz~Y. ~ The author recommends the employment of the chromate and bichro- mate of potash for the estimation of" iron in the common ores of the metal, and especially for the analysis of the clay-band and black-band ironstone of this country. He was led to the application of these salts in the course of some TI - On a new and ready process for the quantitative determination of iron JF - Journal of the Franklin Institute DO - 10.1016/0016-0032(50)90198-0 DA - 1850-11-01 UR - https://www.deepdyve.com/lp/unpaywall/on-a-new-and-ready-process-for-the-quantitative-determination-of-iron-OfE1vqb8zh DP - DeepDyve ER -
