On Fog-rings observed in America. 
By Sir Daviv Brewster, F.R.S.L. §& £., Hon. M.RI.A. 
This notice was communicated to Sir D. Brewster by Sir John P. Boileau. It 
relates to a fog-bow which had been seen in January 1808, by Sir George Rose, 
when off the Montgomery Reach, in the Potomac, in Virginia. Larly in the morn- 
ing a milk-white fog came on, so thick that the captain of the packet found it neces- 
sary to anchor, not knowing where he was. About half-past eleven he came up to 
Sir George, and remarked that they should have all clear soon, ‘‘ for the fog-eater 
was come.” The captain explained himself by pointing to the head of the vessel, 
where there was visible a ring of thicker white fog than that in which they were en- 
veloped, apparently about sixty feet in diameter, the belt of the ring appearing about 
two feet broad. Within this ring was another, two feet in diameter, suspended in 
its centre, and with prismatic colours. It lasted about 20! or 30’, after which the 
fog cleared away. There was a severe frost on the following day. 
Tables of Meteorological Observations for the Year 1844, made by J. R. Crowe, 
Esq., the British Consul-Generab of Norway at Christiana. Latitude 
59° 54! 1" North, Longitude 10° 45' 0" East. 
(Communicated by Dr. Lee.) [These Tables are a continuation of others made 
in the year 1843, and presented to the British Association at York, and noticed in 
the volume of the Proceedings of the Association for 1844, at p. 27 of the abstracts 
of communications to the Section of Mathematics and Physics. ] 
They consist of observations of the thermometer and barometer made on every day 
in the year, at 7a.M., 9 a.m., 2P.M., 4 P.M. and 10 P.m., with the means of each 
column for each month, and the mean temperature calculated for each month, and 
the quantity of rain in cubic inches. 
Also tables of the prevailing winds for each month, the sixteen directions of the 
winds being noted for 9 a.m., 2 p.m. and 4 p.m. on each day, and the totals for each 
month. In February, the state of the wind is also given at 4 p.m. in addition. 
The daily calculations for December are not complete; those for the 11th to the 
20th inclusive are wanting. But the barometrical and thermometrical means for 
_ the whole month at the five above-mentioned hours are given, and the tables of the 
_ prevailing winds are calculated for 7 a.m., 9 a.M., 2P.M. and 4 P.M. 
The following notice was also communicated by Dr. Lee :— 
_ A Description of the Lightning and Thunder of the 16th of August 1844, 
_ whieh took place at Alten, im Norwegian Lapland, by J. F. Coin, Esq. 
N. Latitude 69° 59' + and Longitude 23° + East. 
_ Mr. Cole is the gentleman who, in 1844, presented a paper on the Aurora Borealis, 
as seen frequently at Alten; also a paper on a sudden fall of rain, with a clear sky, 
_ at Alten; also a paper, or table, on the Forces and Directions of the Winds, the 
, Barometer and Thermometer, &c. &c. 
4 Dr. Lee remarked, on presenting these two papers, that although of inferior value 
‘ compared to many which have been presented to the Section, still that they were 
' Hot without some interest, as being a continuation of the series of papers which had 
arrived from Norway and Lapland in 1844, and which are likely to be continued in 
_ future years. 
_ Any observations from Alten are interesting, on account of its high northern 
_ latitude, and being the most northern town in the world, and where it might be highly 
_ advantageous for science that a magnetic observatory should be established, and 
_ which might be done at present with facility, as there is a British mining company 
_ established at Alten, and several of the young men in the employ of the company, 
both English and Norwegians, already have a public library and an astronomical and 
meteorological observatory, and devote their leisure time to these studies, and with 
_ due encouragement and assistance, the work of a magnetic observatory would be 
materially assisted by them. 
_ Either Alten or Hammarfest (which is near it) would be a desirable spot. for a
