The Korn telephotographic apparatus is based on the principle of an apparatus devised by Shelford Bidwell in 1881 for the electrical transmission of pictures to a distance, in which use was made of the change in electrical resistance which selenium undergoes when acted upon by light.
PHILIP DORMER STANHOPE CHESTERFIELD, 4TH Earl Of (1694-1773), son of Philip Stanhope, third earl (1673-1726), and Elizabeth Savile, daughter of George Savile, marquess of Halifax, was born in London on the 22nd of September 1694; Philip, the first earl (1584-1656), son of Sir John Stanhope of Shelford, was a royalist who in 1616 was created Baron Stanhope of Shelford, and in 1628 earl of Chesterfield; and his grandson the 2nd earl (1633-1714) was grandfather of the 4th earl.
In 1715 he entered the House of Commons as Lord Stanhope of Shelford and member for St Germans, and when the impeachment of James, duke of Ormonde, came before the House, he used the occasion (5th of August 1715) to put to proof his old rhetorical studies.
In 1857 he became rector of Water Shelford, Buckinghamshire, and in the following year was appointed Rawlinson professor of Anglo-Saxon at Oxford.
This may, however, be an instance of Miillerian rather than of Batesian mimicry, the beetle being itself inedible; for Shelford has stated his conviction that the Bornean representatives of the sub-family (Clytinae), to which Clytus arietis belongs, are all highly distasteful and are warningly coloured, as are members of this sub-family from other parts of the world.
C. Shelford, a large number of them being in all probability Miillerian.
Finally Shelford states that the anterior end of a Bornean species (C. myodon) offers a striking and detailed resemblance to the head of a snake (Dendrophis pitta).
