Art. VI. — Abstract of a Meteorological Register for 1832-43, 

 kept at Rio de Janeiro ; by John Gardner, Esq. — (Commu- 

 nicated by I. W. Andrews, Professor of Mathematics and Nat- 

 ural Philosophy in Marietta College, Ohio.) 



During a recent short sojourn at Rio de Janeiro, I received from 

 Mr. Gardner, an intelligent merchant of that city, an abstract of 

 a register which he has kept for the last thirteen years. Although 

 limited to a single daily observation of the thermometer, and the 

 general state of the weather, yet I have thought it worthy of pre- 

 servation in a permanent form, and with that view forward it for 

 insertion in the American Journal. The thermometer was ob- 

 served each day at 12 o'clock. Its location was in the second 

 story, within the room, but close by an open window. The tem- 

 perature I should judge to be but little different from that of the 

 external air, in a place protected from direct and reflected heat.

 the discovery of columbic acid was sent in this invoice, and that some 1 

 to the locality from whence it came might be had; but we find no othe ^ jl" J 

 than this which corresponds at all with what Mr. Hatchett says, which is—" f£ 

 referring to Sir Hans Sloan's catalogue, I found that this specimen was on y^ 

 scribed as ' a very heavy black stone with golden streaks/ which prove ^ 

 yellow mica; and it appeared that it had been sent with various s P ecirne nie of 

 iron ores to Sir Hans Sloane, by Mr. Winthrop of Massachusetts. The n *". 

 the mine or place where it was found is also noted in the catalogue ; the

 interesting specimen ; although mineralogists have, on what evidence 

 appear, considered New London as the locality.— Eds.
