Solid when cooling. 



Fractions 1, 2, 8, 4. and f> arc all lighter than water. From the 

 above analysis this sample appears to be a mixture of coal-tar creosote 

 and petroleum. These substances are often used as fly preventatives.

Fractions 3 and 4 contain solid naphthalene. A small amount of 

 alkali is also present. From the distillation test it would appear that 

 this sample consists of .coal-tar creosote which ha- bc'n boiled with 

 resin and an alkali, or with resin, fatty matter, and alkali, to cause 

 it to form an emulsion with water. From the si/e. appearance, and 

 smell of the first fraction it also appears that some carbon bisulphid 

 has been added. It is well known that creosote emulsions have o-j\ -en 

 good roults both as disinfectants and sheep dips. This preparation, 

 therefore, would very likely be of value for the purposes intended.
