Proceedings of the British Association. 309 
eign scientific memoirs, and the sum of £100 was placed at their 
disposal ; and at the meeting in 1839, a further sum of £100 was 
allotted for the same object. The memoirs translated in the first 
year, under the superintendence of the committee, and at the ex- 
pense of the Association, were :— 
1. ‘Remarks on the advancement of magnetical observatories, and a 
description of the instruments to be placed in them,’ (with one e plate) by 
2. ‘Method to be pad during the magnetical term observations,’ by 
Gauss. 
3, Extract from the daily observations of magnetic declination, during 
three years at Gottingen, by Gauss 
4. Description of a small portable apparatus for measuring the abso- 
lute intensity of terrestrial magnetism, (with one plate) by Weber. 
5. “On the graphical representation of the magnetic term observa- 
tions,’ (with two plates) by Gauss. 
For the translation and publication of these in Taylor’s Scien- 
tific Memoirs, the first year’s grant of £100 was paid to Mr. 
Taylor. In the present year, Ohm’s memoif, entitled ‘ The gal- 
Vanic circuit investigated mathematically,’ has been translated at 
the expense of the Association, and given to Mr. T. for the 7th 
and 8th Nos. of the Scientific Memoirs. The Association have 
also paid for seven plates, representing the lines of magnetic de-. 
clination, inclination, and intensity, computed by M. Gauss’s the- 
ory. Tratwlations of the eight memoirs below mentioned, have 
been gratuitously presented to the committee :— 
1. Gauss ‘On a new instrument for the direct observation of the chan- 
ges of the intensity in the horizontal portion of the terrestrial magnetic 
force.’ 
2. Weber ‘ On the arrangement and use of the sie magnetometer.’ 
3. Gauss, ‘ General theory of terrestrial aoe 
4. Encke ‘ On the method of least squa 
5. Bessel ‘On the determination of ass axes of the elliptic spheroid of 
revolution which most nearly corresponds to the existing measurements of 
arcs of the meridian.’ 
6. Weber, ‘ Description and use of a transportable pang hetome ter: 
7. Bessel ‘On the barometrical measurement of novahis. 
8. Rudberg, ‘ Experiments on the expansion of air.’ 
These translations have been placed by the committee, in the 
hands of Mr, Taylor, by whom they have been printed in the 
6th, 7th, and Sth Nos. of the paenipe Memoirs.
