I. So-called Meteoric Stone from Waterloo, Seneca County, New 

 For^.^According to Shepard it contains: Si 78-8, »1 6-28, Pe 8-72, 

 fi'i'VS, Ca,]ilg (iu equal quantities!) and loss 1-45. Rammelsberg con- 

 siders that this is without doubt nothing more than a ferruginous clay. 

 It is for the most part decomposed by chlorhydric-acid, contains much 

 more alumina than above indicated, and 6 pr. ct. of water. On heating 

 it becomes brick-red. 



II. So-called Meteoric Stone from Richland, near Columbia, South Car- 

 olina.— It is a yellow to gray mass, showing occasional blackish point?, 

 and small lustrous kernels of what appears from the hardness to be qu:.

Rammelsberg found that chlorhydric acid had very little action on the sub- 

 stance. He considers that this is also a clay, and suggests that perhaps it 

 IS a fragment of a brick. 



III. So-called Meteoric Iron from Rutherford, North Carolina.- 

 This mass, m which Shepard found, Fe 84-00, Si 13-57, P 1-31, and accord- 

 mg to a partial analysis made in Wohler's Laboratory contains, Fe 87-1, 

 Si 106, C 0-4, is considered by Rammelsberg as northing more than a 

 piece of white pig iron of inferior quality. He found it difficultly at- 

 tacked by acids and determined it to contain 15-7 pr. ct. of silicon.-/o«r-

 Roma, March 1st, 1862— bi-weekly.— We have received the first 10 num- 

 bers of this Meteorological Journal published at Rome, Italy. TheNos. are 

 issued once a fortnight, each No. consisting of eight large quarto pagess 

 beautifully printed. They contain the meteorological, magnetic and 

 electric observations made at the Roman College under the direction ot 

 Father Secchi, with full meteorological notes, and also dissertations upon 

 questions relating to terrestrial magnetism, to atmospheric ejec-
