“ The “basic process” invented by Thomas was especially valuable on the continent of Europe, where the proportion of phosphoric iron is much larger than in England, and both in Belgium and in Germany the name of the inventor became more widely known than in his own country. In America, although non-phosphoric iron largely predominates, an immense interest was taken in the invention. But Thomas had been overworking for years, and his lungs became affected. A long sea voyage and a residence in Egypt proved unavailing to restore his health and he died in Paris on the 1st of February 1885. ”
