Benzoline is highly inflammable, and is often called mineral naphtha, petroleum naphtha, and petroleum spirit. Benzoline is not the same as benzene or benzol, which is one of the products of the dry distillation of coal. From its very general use as a fuel in motor-cars many accidents have happened from inhaling the vapour of petrol.

Ordway, potassium chloride was added to the soap solution partially separated by ether and water. This caused an immediate and complete separation. By the use of potassium chloride it was found possible to effect a separation with benzol and water, also with naphtha and water. Another means of separation was tried by precipitating the calcium salts, from a solution of the potash soap.

If they are, you will have to disarticulate them, clean them with benzol and, if necessary, remacerate and bleach; but whatever you do, I concluded solemnly, 'be careful with the chlorinated soda or you will spoil the appearance of the bones and make them brittle. Good bye! I shook his hand effusively and he took his departure very glum and crestfallen.

Those who recently hastened away from Paris in search of a place of refuge, quiet, and safety, have met with many disappointments. The roads to Tours are blocked with vehicles of every description, many of them filled with refugees who have turned them into temporary dwellings. Automobiles are brought to a standstill for lack of benzol.

I pointed to benzene or benzol in the table as a hydrocarbon, C H , which forms a principal colour-producing constituent of coal-tar. If you desire to produce chemical appetite in benzene, you must rob it of some of its hydrogen. This is the first step in the formation of aniline.

The mother solutions must be speedily evaporated if we still wish to obtain crystals; after a time they will only furnish a resinous residue. The hop-bitter acid melts at 92 deg. to 93 deg.. It is easily soluble in alcohol, ether, benzol, chloroform, sulphide of carbon, and vinegar; to a lesser extent in cold petroleum ether, and not at all in water.

In 1825 and 1826 Faraday published papers in the 'Philosophical Transactions' on 'new compounds of carbon and hydrogen, and on 'sulphonaphthalic acid. In the former of these papers he announced the discovery of Benzol, which, in the hands of modern chemists, has become the foundation of our splendid aniline dyes.

It has been found possible to gradually range most carbon compounds under two categories, either as marsh-gas or as benzol derivatives, as fatty compounds or as aromatic compounds. To do this, methods of analysis very different from those used in mineral chemistry had to be applied. The mere finding out of percentage composition tells us little or nothing about an organic compound.

Captain Harold C. Woodward of the Corps of Engineers, a Government specialist on explosives, held that if the amount of explosive, either trinitrotoluol, or an explosive made from chlorate of potash and benzol, required by the mine caskets found in Fay's possession, was fired against a ship's rudder, it would tear open the stern and destroy the entire ship, if not its passengers and crew, so devastating would be the explosive force.

France is also to receive annually for three years 35,000 tons of benzol, 60,000 tons of coal tar, and 30,000 tons of sulphate of ammonia. In the event of such postponements or cancellations "the coal to replace coal from destroyed mines shall receive priority over other deliveries."
