 His experiments were made in a little workshop behind his home at Friedrichsdorff; and wires were run from it to an upper chamber. Another line was erected between the physical cabinet at Garnier's Institute across the playground to one of the class-rooms, and there was a tradition in the school that the boys were afraid of creating an uproar in the room for fear Herr Reis should hear them with his 'telephon.'

The new invention was published to the world in a lecture before the Physical Society of Frankfort on October 26, 1861, and a description, written by himself for the Jahresbericht, a month or two later.

It became a subject for popular lectures, and an article for scientific cabinets. Reis obtained a brief renown, but the reaction soon set in. The Physical Society of Frankfort turned its back on the apparatus which had given it lustre. Reis resigned his membership in 1867; but the Free German Institute of Frankfort, which elected him an honorary member, also slighted the instrument as a mere 'philosophical toy.' At first it was a dream, and now it is a plaything. Have we not had enough of that superior wisdom which is another name for stupidity? The dreams of the imagination are apt to become realities, and the toy of to-day has a knack of growing into the mighty engine of to-morrow.

But rebuffs had preyed upon his sensitive heart, and he was already stricken with consumption. It is related that, after his lecture on the telephone at Geissen, in 1854, Professor Poggendorff, who was present, invited him to send a description of his
