1. The so-called Antimony blue—A year or more ago, a new 
coloring matter was introduced into commerce under the above 
ce) ed the blue compound. In 
further proof of this assumption, he found that the antimony could 
be satisfactorily replaced by mercury. The use of antimony accel-

ducing ferric chloride. Water abla, restores the color. It is 
not soluble in water, is at once decomposed by caustic alkalies, and 
in powder has the coppery reflection of prussian blue. It is there- 
fore only another of the blue compounds of iron and cyanogen, and 
the name “antimony blue,” given to it is a misnomer.— Woniteur

2. On the Alloys of Hydrogenium with Palladium, Potassium 
tube of glass, connected at one end with a manometer, and at the 
other with a Sprengel pump. Operating at the temperature 0 
00° ©., with palladium charged in different degrees, the results 
show: Ist, that when the volume of the absorbed hydrogen is 
* Since palladium thus saturated loses hydrogen at the ordinary temperature, 
and since on to the air, it heats, i 
authors adopted the plan of placing it at once in water free from air, and heating 
this to boiling, the gas evolved being measured. It was then treated as above.
