Miscellanies. 195 



no doubt, that were the use of ardent spirit entirely abandoned to the 

 arts, to science, and, in some few cases perhaps, to medicine, society 

 would, in a few years, wear an entirely new aspect. We are cer- 

 tain that this would be the result upon the largest scale, because the 

 experiment is already completely successful on the smaller scale, up- 

 on which it has been made. We have not merely heard the fact — we 

 have seen it; we know it; and no evidence can weaken the conviction 

 resting upon our minds. In physics, experiments, although success- 

 ful on a small scale, sometimes fail on the large ; but, not so in mor- 

 als ; the virtue of a good man repeated in every other man, would 

 make the whole community good, and the same is strictly true of tem- 

 perance, and of every thing that depends upon it. There is not 

 one reason, nor the shadow of a reason, for the habitual use of ar- 

 dent spirit ; it does only harm ; it is both physically and morally nox- 

 ious, and if persevered in, it is fatal to every interest, and to every 

 hope. 



8. JVoiice of Cobalt, JVickel, ^c. of the Chaihnm mine, Connec- 

 ticut, in a letter from Mr. A. A. Hayes to the Editor, dated Rox- 

 bury Laboratory, Aug. 29, 1S31.-^-l have done nothing in experi- 

 mental chemistry for some time, except making an examination of 

 a specimen of the produce of the Chatham mine. The operations, 

 it seems, were unskilfully conducted, and the whole produce of 

 metal, seven or eight hundred pounds, is now in the market. Its 

 value as a coloring material in the pottery manufacture, was the ob- 

 ject ; but having detected antimony in an assay with the blowpipe, 

 I was lead to make a careful analysis of it. It is a black powder 

 containing, in one hundred parts 



Unexamined insoluble matter, 3.00 Oxide of Iron, G.15 



Sulphur, 8.92 " Cobalt, 17,30 



Arsenic, 1G.25 " Nickel, 43.85 



Antimony, 4.50 



99.97 

 exclusive of hygrometic water. The numbers approach nearer the 

 original quantity than we should expect from the circumstance that 

 the "oxide of nickel" may be in the specimen, in part metallic nickel. 

 The antimony was separated from the yellow sulphuret of arsenic, in a 

 current of hydrogen, as pointed out by Rose. 



I thought it might be interesting as a discovery, as it may lead min- 

 eralogists to look for nickeliferous antimony, among their specimens 

 of arsenical nickel from this locality ; and we shall probably mention
