Professor Hart stated, for the information of the Society, 

 that the Transit Instrument at the Observatory of the High 

 School is now in complete operation, and that observations are 

 made with it nightly. 



Dr. Bridges made some observations on the affinity between 

 certain metals, and especially on the belief that iron and mer- 

 cury cannot be amalgamated. He exhibited a specimen in 

 which such amalgamation existed. He first observed this ac- 

 cidentally. The mercury in the specimens adhered very 

 firmly to the iron. 



Mr. Lukens referred to cases in which the amalgamation 

 had been efiected when an iron plate was scraped under mer- 

 cury; in other words, when the contact of air was prevented. 



Dr. Patterson, on the part of the Committee of Finance, 

 made a report, recommending three hundred dollars to be ap- 

 propriated for the publication of the Society's Transactions, 

 which, on motion, was agreed to.
