A striking example of the awe inspired by the chemist in those days was that only with great difficulty could he obtain a man or a boy to assist him in the laboratory.

He was suspected of illicit intercourse with the Powers of Evil when he undertook to tell by his suspicious-looking apparatus what a stone contained.

I believe that at last we had to send him a man from our office at Pittsburgh.
One day he sent us a report of analyses of ore remarkable for the absence of phosphorus.

It was really an ore suitable for making Bessemer steel.

Such a discovery attracted our attention at once.
