PREFACE TO THE SECOND VOLUME.
In the Advertisement to the Seventh Part of the Scientific Memoirs the Editor has already acknowledged the assistance afforded to the work by the British Association for the Advancement of Science, concurring, as it has done most efficiently, with the other public bodies and individuals by whom the success of the undertaking had been promoted. It is now his pleasing duty to state, that the support thus given having afforded an opportunity for the plan and objects of the work to become more generally known, the sale has been so far increased as to give an improved prospect of its permanence; and that a portion of the Third Volume is already in the press.
Of the Memoirs contained in Part VIII. the following have been received from the Committee of the British Association for procuring the translation and publication of Foreign Scientific Memoirs, viz.:—
The Galvanic Circuit investigated Mathematically. By Dr. G. S. Ohm. Continuation.
Bessel on the Barometrical Measurement of Heights.
Rudberg on the Expansion of Dry Air.
Weber on a Transportable Magnetometer. With a Plate.
Weber on the Magnetic Term-Observations for 1839 of the German Magnetic Association. Extract. With a Plate.
Goldschmidt On the Observations of Magnetic Declination at Göttingen.
The continuation of the translation of Ohm's Memoir has 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.
