point was very high, being 87° C. It was kept meUed for 

 some time to drive off any adhering aether, then dried under 

 the air-pump and subjected to analysis. 



I. 0*316 grm. gave 0*7658 carbonic acid and 0*114 water. 



II. 0*321 gave 0*7755 carbonic acid and 0*1116 water. 

 HI. 0*3805 gave 0*9183 carbonic acid and 0*1408 water. 



IV. 0*2122 gave 0*1380 chloride of silver = 16*04 chlorine. 



V. 0*2505 gave 0*1675 chloride of silver = 1649 chlorine. 



VI. 0*177 gave 0*1155 = 1609 chlorine.

The substance employed for these analyses was prepared 

 at three different times. I am sorry to say, however, that I 

 have been unable to deduce any probable formula from these 

 analyses. 



When this crystalline compound is heated in an alcoholic 

 solution of potash, benzoate of potash, chloride of potassium 

 with a little benzoic aether are immediately formed, the colour 

 of the solution becoming at the same time of aji inky blackness. 

 When this alkaline solution is treated with an excess of mu- 

 riatic acid, the benzoic acid precipitates on the cooling of the 

 liquid. The benzoic acid is mixed with a good deal of a dark- 

 coloured tenacious semifluid resin, which has a strong empy- 

 reumatic smell, exactly similar to that of creosote; so that 

 chloride of potassium and benzoic acid are not the only pro- 

 ducts of this decomposition. The benzoic acid was purified 

 by repeated crystallizations and subjected to analysis.

The liquid chlorine compound already mentioned can rea- 

 dily be dissolved out of the bibulous papers by treating them 

 with aether. The liquid compound however always retained 

 a considerable quantity of the crystals dissolved in it, just as 

 oleine does margarine or stearine in the fats, so that I was quite 

 unable to purify it. This is much to be regretted, as it ap- 

 peared to be much the more interesting of the two, as it is that 

 which possesses the very pungent smell already mentioned.
