Robert Walsh, jun. Esq. has issued proposals for publishing by subscription, a Historical Dictionary of Eminent Americans. The Prospectus contains the following paragraph. "To prevent misapprehension and disarm political prejudice, the Editor emphatically states, that he aims at furnishing a record of simple incidents; of meritorious services and laudable qualities-he will use no colouring of party, admit no invidious interpretations, enter into no discussions, and abstain from all reflections, except those which may tend to increase the efficacy of bright example." It is hoped that such a work, undertaken with such views, will receive every encouragement.

Meteorology.

METEOROLOGICAL OBSERVATIONS, BY J. F. DANA.

The following table exhibits the results of thermometric observations, made at Hanover and at Portsmouth, N. H., during the year 1822. The observations at Hanover were made at 10 o'clock morning and evening, as it appears from a series of observations made for the purpose,that the mean of observations made at those hours, approaches nearer the mean of the extremes of heat and cold, as ascertained by the self-registering thermometer, than those made at other times of the day.

The Thermometer employed at H., is one of W. and S. Jones' best kind, and has been compared with a standard thermometer, made by Troughton, in my possession; it is suspended about five feet from the ground, in a northern exposure, and about 160 feet above Connecticut river.

The observations at Portsmouth were made at four different times of the day, viz., at 7, A. M., and at 1, 6, 9, P. M., and are copied from the N. H. Register, for 1823. It is evident that no other information can be derived from a comparative view of the "Greatest Observed Height," at two places, than simply the fact, whether the greatest elevation occurred in both places on the same day, since the observations at Portsmouth were made near mid day.

It appears, from the above tables, that the thermometer rises higher and falls lower at Hanover than at Portsmouth, or that the temperature at the latter place is more equable; and this depends, without doubt, on the influence of the ocean, which prevents great excess of cold and heat.-The annual mean temperature at Portsmouth, is also a little greater than at Hanover.

It will be noticed, also, that excepting in the months of February, March, September and November, that there the mean of the observed monthly extremes corresponds very nearly with the monthly mean, in the observations made at Hanover, at 10 o'clock morning and evening, and more nearly than in those made at Portsmouth, at 7, A. M., and 1, 7, 9, P. M.-a fact which is in perfect coincidence with the results of the experiments made for the purpose of ascertaining the best times of day for making meteorological obser vations, and which is found to be at 10 o'clock, morning and evening. It is a desideratum, that those, who do not possess self-registering thermometers, and who cannot consequently give us the actual extremes of temperature, should make their observations at those hours, whose mean results approach nearest to the mean of the actual extremes.

TABLE IV.

Exhibiting the monthly results of Barometrical observations, made at Hanover, in 1822.

The Barometer, used in making these observations, is a Mountain Barometer,of Sir H. Englefield's construction, and was made by Thomas Jones, a pupil of Mr. Ramsden.-The observations were made at 10 o'clock, morning and evening.

List of the Counsellors and Representatives in New-Hampshire

in 1767.

Under the Royal government of New-Hampshire, though we had the privilege of electing the house of representatives, the governor was appointed by the King.-There was a council consisting of twelve with the lieutenant governor, of which the governor had a right to negative the choice of any one who was objectionable in his view, or did not appear in the favor of the prerogative. The last royal gov ernor of New-Hampshire was John Wentworth, who died at Halifax on the 8th of April, 1820. It may afford some interest to give a list of his council in the year 1767, together with the names of those who were representatives that year.

Amherst and Bedford, Col. John Goffe.

In 1748, there were represented in the province of NewHampshire, only 14 towns, by 20 representatives; in 1767, there were 31 towns represented by an equal number of members, some sending two or three, and others being clas sed for sending one. At the present time we have about 200 representatives.
