was abundantly sufficient to bear the statical pressure of the sur- 

 rounding water, he found it crushed inward after the explosion. 



Judge Hopkinson deposited with the Society, the Log Book 

 of the first voyage in a steam vessel across the Atlantic, by 

 Captain Rogers, in the year 1819; an account of which was 

 given in the Proceedings of the Society, No. 2, p. 14. 



In a written communication, Judge Hopkinson stated, amongst other 

 matters in reference to Captain Rogers's priority, that he was on 

 board the steam ship, lying at the City of Washington, after her re- 

 turn from the voyage. She was built and rigged like one of the 

 Liverpool packets ; and her wheels were made to fold up at her 

 sides, when the wind permitted her sails to be used. 



The Log Book states, among the occurrences usually noted, the 

 days when the steam was used. 



Dr. Hare made some observations on Professor Loomis's 

 views of storms, read at the last meeting; also, oh the mode in 

 which storms may be induced by the meeting of opposite cur- 

 rents, and the ascent of an intervening mass of air; on the 

 agency of electricity in their production, &c. &c. 



Dr. Hare asked permission to withdraw his paper, presented 

 at the last meeting of the Society, which was agreed to. 



He stated that he was about to perform some experiments, the re- 

 sults of which it. appeared to him desirable to publish with his essays, 

 and he was fearful that the subject could not be described satisfac- 

 torily without quotations from previous publications, which might 

 not be consistent with the limits allowed to articles published in the 

 Transactions.
