The original or acid Bessemer process had, however, two disadvantages-.—(1) phosphorus and sulphur could not be removed owing to the reduction of their oxides by iron and, therefore, only special Bessemer pigs, free from phosphorus and very low in sulphur, could be used (2) the ingots produced contained blow-holes. Science overcame the first of these disadvantages. In 1879 Thomas and Gilchrist found...

Thomas and King s and our own studies on polyethylene and a recent investigation of polypropylene by Gilchrist, we believe that the loss peak at below 4.2 K in these four films is due to the presence of an antioxidant, whose contribution to the dielectric loss in the 4 to 10 K range was not eliminated by annealing. 

The recently discovered methods of producing iron and steel, such as the processes of Bessemer, Siemens, Gilchrist-Thomas, etc., cut to a minimum at relatively small costs the formerly arduous processes. The making of alizarin, a red dye-stuff extracted from coal-tar, requires but a few weeks, and this by means of already existing coal-tar dye-producing installations, to yield the same results which formerly required years. It took a year for the madder to mature, and it was customary to let the roots grow a few years more before they were processed.8...
