and burns with a strong yellow flame, emitting much smoke. 

 It boils at 168° C. Its specific gravity is i-1006 at 27° C. 

 It is pretty soluble in water, and mucli more so in alcohol 

 and aether. Potassium effervesces strongly when placed in 

 it, but neither the alcoholic nor aqueous solution of potash 

 has any effect upon it. Solid potash, with the assistance of 

 heat, converts it into a brown resin. It dissolves iodine very 

 easily, liut without any violent action even when heated. In 

 the cold muriatic acid gives it a fine red colour, and with the 

 assistance of heat turns it into a dark brown resin. Nitric 

 acid first reddens, then chars it. Sulphuric acid has a si- 

 milar effect. 



The results of its analyses are as follows : 



I. 0-330 substance gave 0*747 carbonic acid, and 0-130 

 water. 



II. 0-324 gave 0*725 carbonic acid, and 0-1275 water. 



III. 0*3185 gave 0*7205 carbonic acid, and 0-128 water. 



100-00 100-00 100-00 99*99 



This gives the formula: 



Carbon 5 atoms =382*175 



Hydrogen 4 atoms = 24*959 



Oxygen 2 atoms =200*000 



Atomic weight 607*134 

 It is evident that this oil has a very different composition 

 from oils in general, as it contains oxygen and hydrogen only 

 in the proportions to form water, while all other known oils 

 contain a great excess of hydrogen,

 HE object of the present pa})er is to show that the real 

 aspirates of K and G are not the sounds that are ge- 

 nerally considered as such ; in other words, that they are
