STATISTICS. 
Pror. Jounston reported the progress made by the Com- 
mittee appointed at the Newcastle Meeting to inquire into the 
Statistics of the Mining Districts. 
MECHANICAL SCIENCE. 
On the Forms of Vessels.—By a Committee, consisting of 
Sir J. Robison, J. S. Russell, Esq., and James Smith, Esq. 
On THE TRANSLATION OF FOREIGN SCIENTIFIC MEMorRs. 
At the Meeting of the British Association at Newcastle in 
1838, a Committee was appointed for the purpose of procuring 
and publishing translations of foreign scientific memoirs, and a 
sum of 100/. was placed at their disposal: and at the Meeting 
at Birmingham 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 expense of 
the Association, were— 
1. Remarks on the arrangement of magnetical observatories, and a descrip- 
tion of the instruments to be placed in them (with one plate), by Weber. 
2. Method to be pursued during the magnetical term-observations by 
Gauss. 
3. Extract from the daily observations of magnetical declination during three 
years, at Gottingen, by Gauss. 
4. Description of a small portable apparatus for measuring the absolute in- 
tensity of terrestrial magnetism (with one plate), by Weber. 
5. On the graphical representations of the magnetic term-observations (with 
two plates), by Gauss. 
6. On a new instrument for the direct observation of the changes of the 
intensity in the horizontal portion of the terrestrial magnetic force, by Gauss. 
7. On the arrangement and use of the bifilar magnetometer, by Weber. 
For the translation and publication of these in Taylor’s Sci- 
entific Memoirs, the first year’s grant of 100/. was paid to Mr. 
Taylor. 
In the present year, Ohm’s memoir, entitled “‘ The Galvanic 
Circuit investigated mathematically,” has been translated at the 
expense of the Association, and given to Mr. Taylor, for the 
seventh and eighth numbers of the “‘ Scientific Memoirs.” The 
Association have also paid for seven plates contained in the 
seventh number, representing the lines of magnetic declination, 
inclination and intensity computed by M. Gauss’s theory. The 
sums paid for these plates and for the translation of Ohm’s
