discrepancy as to the state of oxidation of the latter, tend to show 

 a close connexion between the Elie mineral and pyrope. The occur- 

 rence of oxide of chromium in both minerals, and their specific 

 gravity, which is 3*661 for the Elie mineral, 3- 78 for pyrope, while 

 that of precious garnet exceeds 4* , lead to a similar view of this con- 

 nection. — Jameson's Journal, Oct. 1845. 



ANALYSIS OF METEORIC IRON FROM BURLINGTON, OSTEGO 

 COUNTY, NEW YORK. BY MR. C. H. ROCKWELL. 



In the year 1819 two or three masses of native iron, as it ap- 

 peared to be, were procured from the farmer who first turned it over 

 with his plough, in a field near the north line of the town of Bur- 

 lington, Ostego County, New York. These consisted of remnants of 

 an entire mass originally supposed to weigh between one and two 

 hundred pounds, and found several years before. It had been in the 

 forge of a country blacksmith, and the whole heated in order to en- 

 able him to cut off portions for the manufacture of such articles as 

 the farmer most needed. 



The mass was divided by broad lamina?, crossing each other at 

 an angle of 60° and 120°, cutting up the surface into triangular and 

 rhombohedral figures. It broke with a hackly fracture, and only 

 with the greatest difficulty on the thinnest edges. 



Two deep and broad sutures marked its two most regular oppo- 

 site faces, made by the wedge or chisel by the smith, who severed 

 it from the adjoining portion. It bore the marks of having been 

 intensely heated in the forge, and numerous microscopic crystals, of 

 a black colour and brilliant lustre, covered some parts of it's surface ; 

 they resembled phosphate of iron, but were too small to be detached . 



The specific gravity was 7'501 ; it dissolved quickly and com- 

 pletely in nitric acid, with the application of a gentle heat. The 

 solution, treated with nitrate of silver, gave no cloudiness, showing 

 the absence of chlorine ; it yielded by the usual process for sepa- 

 rating iron from nickel.

PREPARATION OF CHLORO-ACKTIC ACID. 



M. Malaguti recommends the following process for the prepara- 

 tion of chloro-acetic acid readily and in large quantity : — Let chlorine 

 act upon sulphuric aether, by which sesquichloride of carbon is ob- 

 tained, and then the water which is suffered to remain in the bottles 

 with the rough product is merely a solution of chloro-acetic and hy- 

 drochloric acids; or perchloric aether is prepared, and by distilling it 

 and causing the product of the distillation to mix with water, a so- 

 lution of chloro-acetic and hydrochloric acids is obtained. In both
