Although but boys, both were fired at this interview with enthusiasm for electric science.

Both have been for many years Professors in the University of Glasgow.

The elder, Professor James Thomson, is well known for his useful inventions and ingenious papers on many branches of science.

The younger, Sir William Thomson, ranks over the world as prince of electricians, and second to no living man in scientific reputation.
Dr.Graham's assistant devoted himself to practical chemistry, and made for himself a brilliant name by the purification of petroleum, adapting it for use in private houses, and by the manufacture of paraffin and paraffin-oil.

Few men have made the art to which they devoted themselves more subservient to the use of man than he whom Livingstone first knew as Graham's assistant, and afterward used to call playfully "Sir Paraffin." "I have been obliged to knight him," he used to say, "to distinguish him from the other Young." The "other" Young was Mr.E.D.
Young, of the Search Expedition, and subsequently the very successful leader of the Scotch Mission at Lake Nyassa.
