been paid for out of the grant at the disposal of the Committee; as have the Plates for the two Memoirs of Professor Weber.
The translation of Rudberg's experiments has been presented to the Committee by Professor W. H. Miller, of Cambridge; and the translation of the Memoirs of Bessel, Weber, and Goldschmidt, by Major Sabine; and by the Committee to the Editor.
The Editor has also to acknowledge the valuable assistance which he has received from Professors Miller and Wheatstone in the revision of the translation of Ohm's Memoirs, and of Professor Graham and Richard Phillips, Esq., for similar services with regard to the Chemical Memoirs. To the friendly and zealous cooperation of Major Sabine he is also most especially indebted.
