Nairne and Blunt, and is similar in construction to one made by the same artists, and described by the Hon. Henry Cavendish in the 66th volume of the Philosophical Transactions, as used in the house of the Royal Society. Previously to delivering it into my charge, Mr. Browne had adjusted the balance of the needle by means of the screws on the cross of wires attached to its axis so that no alteration took place in the indication of the dip, on reversing the poles. |
