He transmitted a message about 150 yards from the old Clarendon Laboratory to the University Museum. He provided his laboratory facilities to conduct the first clinical use of X-rays in England (7 Feb 1896), at the request of surgeon Sir Robert Jones (1855-1933), to examine the wrist of boy who had accidentally shot himself.
