It appears then that when salicine is treated with peroxide 

 of lead, formate of lead and the combination of lead and sa- 

 licine are the results. 



Salicone. — When salicine is intimately mixed with half its 

 weight of quicklime and subjected to destructive distillation, a 

 quantity of a heavy reddish coloured oil and some water pass 

 into the receiver, while carbonate of lime, mixed with charcoal, 

 remains in the retort. The oil has a very pungent taste, and 

 an empyreumatic smell, somewhat resembling that of crea- 

 sote. It was rendered colourless by one or two rectifications 

 which deprived it of most of its empyreumatic odour. Alkalies 

 in the cold had no effect upon it, "but when heat was applied 

 the oil was changed into a dark resinous mass. Nitric acid 

 attacked it violently, even in the cold, with the evolution of 

 deutoxide of azote. Sulphuric acid reddened it in the cold, 

 and when assisted by heat blackened it, and gave off sul- 

 phurous acid. It dissolved iodine very readily, but with- 

 out explosion, even when heat was applied. When rectified 

 the first and last portions of the oil were rejected. The middle 

 portion had a specific gravity of 1-0212. It began to boil at 

 260° Fahrenheit, but the boiling point gradually rose to 272° 

 Fahrenheit. It was rendered anhydrous by being allowed to 

 stand for some days over fused chloride of calcium. When 

 subjected to analysis,
