and then gradually diminishing in frequency. While every other meteoric period has intermitted, this of August holds out with little change.

The observations below stated were made in the open air, from the top of the southern tower of the Alumni Building of Yale College, by a corps of observers consisting of J. W. Gibbs, Jr., Charles Tomlinson, J. W. Johnson, W. C. Johnston, H. W. Siglar, J. B. Chase, with myself. During the hour from 2h to 3h A. M., there were but six observers. Each meteor was called aloud, and no one was reckoned twice. Between 10 P.M. of the 9th and 3 A.M. of the 10th of August, 1860, we observed s. hundred and sixty-five different shooting stars, distributed as folOWs, viz:

[ocr errors]

The meteors were reckoned in that quarter where they first became visible, but it is of course impossible to indicate satisfactorily by words their distribution on the face of the sky. The majority of them were inferior in brilliancy to stars of the second magnitude. Many however were as bright as stars of the first magnitude, and a few rivalled in splendor Mars and Venus. Several of them left luminous trains, but none appeared to explode. Their general Southwesterly direction was evident, and as nearly as we could estimate, at least three fourths of all conformed to the radiant of former years, in the vicinity of the swordhandle of Perseus.

During our watch the sky was clear except that between 1h and 2h A. M. there were some clouds about the west. The moon in her last quarter embarrassed our view after 11 P.M., and doubtless concealed about one third of all the meteors which might have been seen in her absence. At 3 A. M. mist was forming rapidly, but we saw after that hour five meteors not included above; and while we were arranging for the watch a few minutes previous to 10h we saw eighteen, making a total of 588 meteors observed by us during five hours and ten minutes. Had the moon been absent we should probably have seen 800 during this

eriod. This is not far from six times the common nightly average for It is perhaps hardly worth mentioning that the Aurora Borealis was visible all night, being by turns quite active after twelve o'clock. This phenomenon has been seen here with uncommon frequency this summer, but it appears to have no special connection with shooting stars.

1. The Fourteenth Meeting of the American Association for the Advancement of Science, was held, August 1st–8th, 1860, at Newport, R. Island, in the old State House, dating from the Colonial times under Queen Anne. The Hon. W. H. Cranston, Mayor of Newport, pronounced an address of welcome from the city of Newport, to the members of the Association. The general enjoyment of the occasion was amply secured by the kind and abundant hospitality of the city and its citizens, leaving on all who participated the most agreeable impressions of Newport. The weather was superb, neither fog or rain marred the pleasure of the unequalled drives by beach and shore over this American Isle of Wight, and the Geologists with Mr. Hitchcock's map" of the Island in hand found the conglomerates of ‘Purgatory’ and ‘Paradise” and the graphitic anthracite of these most overdone and contorted coal measures a fruitful theme of discussion both in hall and field. The numbers in attendance at the Newport meeting were small compared with most previous meetings. An erroneous impression appears unfortunately to have gone abroad that Newport was a very costly place to visit and that the “height of the season' at a great watering place was not a time when science could hold ground against fashion. While all this was eminently untrue, the effect of such an impression was visible in the absence of numbers of familiar faces. Neither can we, if we would, conceal the fact that while many papers of marked ability were presented, the character of this meeting was not in all respects creditable to American Science. A conviction prevailed among many who were present at Newport of a decadence in the scientific character of the Association, of a loss of tone which if not already a demoralization threatened soon to become such. There was a time when weak speculations—by whomever put forth—were promptly trampled on and their authors made to feel that they were answerable to a power of united public sentiment which bore rule with a righteous severity. The evidence of this power was wanting at Newport—signs of concession to scientific charlatanism were visible in quarters where we least looked for it, and we left the meeting with a persuasion that unless the old order of proceedings could be restored, the American Association must come to a speedy and disastrous end. We do not despair of the immediate restoration of a higher standard—the effort will certainly be made. One of the bright points of the Newport meeting was the opportune return of the Labrador Astronomical Expedition, sent out under the auspices of the United States Coast Survey and under the immediate sci

entific leadership of Prof. Stephen Alexander of Princeton, to witness the total Eclipse of July 18th. As we elsewhere give a detailed statement of the results from the pen of one of the expedition, it is only necessary to add that the “Bibb" made Newport harbor on her return in season to secure an agreeable reunion on Tuesday evening, and that on Wednesday morning Prof. Alexander recounted the results of the Expedition to that land of ‘monumental desolation’ in a brief but fervid recital, deeply moving his audience by his peculiar eloquence. It was a happy circumstance that the meeting could close under so agreeable an impression.

The address of the retiring President, Prof. Stephen Alexander, was delivered on Wednesday morning, just before the adjournment, and will appear in the Transactions of the year.

Prof. Bache gave an interesting public discourse reviewing the history of discovery, and the method of investigation employed in regard to the Gulf Stream. This address we hope to present to our readers in full in a future number of this Journal, as also the substance of another public address by Prof. Henry, on Atmospheric Electricity, delivered as a popular evening lecture at Newport, by the distinguished Secretary of the Smithsonian Institution.
