feet under ground, and still warm. The largest piece weighed 7 

 Vienna pounds and 6j loths, and the whole 12 pounds. The exte- 

 rior is partly black or dull gray, and much blebby or subscoriaceous, 

 it being covered with a thin crust. The interior is ash-gray, and 

 irregularly line-granular. Its specific gravity is 5'242. It afforded 

 18*26 per cent, of magnetic material, and 81 '74 non-magnetic. The 

 former was found to contain — Iron, 85' 14 ; nickel (with some co- 

 balt), 10-06; copper and tin, 0-40; sulphur, 4'19 ; phosphorus, 

 0'18 = 99-97. Separating 11-53 as FeS'-, the composition of the 

 iron corresponds to — iron, 87'96; nickel, 11-38; tin and copper, 

 0-46; phosphorus, 0-20. 



The non-magnetic part was partly soluble in muriatic acid. The 

 soluble and insoluble parts consisted of —

2. Insoluble. 57-29 4-20 12-08 3-90 17-67 1-14 3-72 

 The soluble part corresponds nearly to olivine ; the insoluble to 



34-93 per cent, oligoclase, and 65-59 pyroxene. From these two 

 analyses there were excluded — from the first, before deducing the 

 per-ccntage, 0-82 sulphuret of iron, and 13-09 nickeliferous iron; 

 from the second, TOO chromic iron. — ^\\Y\m.^n'& American Journal

ON CRYSTALLIZED VALERIANATE OF ATROPINE. 

 BY H. CALLMANN. 



This salt forms perfectly wliite and light crusts ; the crystals 

 appear to belong to the rlioniboidal system, and the faces are very 

 brilliant. At a temperature of 68° F. the crystals soften, and at 

 .57°-6 F. they are liquefied. Under the double influence of air and 

 light, they soon acquire a yellow colour. The carbonic acid of 

 the air displaces a certain quantity of valerianic acid, which is 

 recognizable by its peculiar odour. 



The cryslaUized salt presents the various reactions of the salts of 

 atropine and of tlie valerianates. It is extremely soluble in water, 

 less so in alcoiiol, and still less in aetiier. The analysis of the salt, 

 dried in vacuo at the ordinary temperature, gave: —

CRYSTALLIZED FURNACE-PRODUCTS, 



We are requested to state that the furnace-products which are 



said by Professor Miller, in his communication to the Magazine for 



October, to have been received by Dr. Percy from the United States, 



■were sent to the latter by Professor Brush, of Yale College. — W. F.
