Ann., Vol. CXI. p. 415. Oph-thal′mo-scope. An instrument for inspecting the interior of the eye, invented by Professor H. Helmholtz, and described by him in 1851. He attributed the difficulty experienced in viewing images formed on the retina to the fact that the refractive humors of the eye cause it to be focused at the p to the crank. It was invented by James Watt, and was brought into use by Maudslay. Watt's model, made at Soho in 1763, was exhibited at the London Exhibition of 1851.

This cable was covered with iron wire, contained 4 conducting wires, was 27 miles in length and weighed 6 tons per mile. It was a permanent success. The next of cable were constructed to meet contingencies. h is the cable which it was attempted to lay down between Portpatrick and Donaghadee, Scotland and Ireland, in 1851. Owing to a gale, it was cut when 16 miles had been paid out. It was subsequently recovered in 1854, the depth of water being 150 fathoms, and found in good preseried in the air, and baked in a kiln.
