CREOLIN. 
By Professor Dr. Froliner, Director of the Pharmacological Institute of the 
Royal Veterinary College in Berlin. 
[ Translated from the German.'] 
Under the name of Creolin the firm of Messrs. William 
Pearson and Co., of Hamburg, have brought before the no¬ 
tice of several German institutes and corporations a new disin¬ 
fectant and antiseptic. I must candidly confess that with a 
daily increasing mass of new medicines I have only entered 
with very great reserve on a thorough examination of this 
material from a chemical and pharmacological point of view. 
An examination of three months has, however, shown that 
creolin may be looked upon as quite a material enrichment of 
our medicine chest. According to the information of the 
above firm, creolin is a product of dry distillation of coal, and 
indeed of a peculiar description of English coal. From these 
distillations of coal creolin is prepared by the addition of 
alkali in suitable and proportionate degrees. As regards the 
further chemical composition no details have been given by 
the firm, as the material has been for years patented in Eng¬ 
land. However, it is said to be a constant chemical substance. 
The material produces a blackish, syrupy, pungent and 
tar-smelling liquid, which is packed in tins of 5 kilos, each. 
It is miscible with water in all proportions. The solution 
forms a milky emulsion. It dissolves also in alcohol. Be¬ 
sides the pure creolin and its solution in water and alcohol, 
there were also submitted for examination hard and soft creo¬ 
lin soaps, and also creolin powder for the disinfection of 
rooms, dens, etc. As a net result of my experiments with 
this material, it has been shown that creolip is non-poisonous, 
both volatile and permanent, and is a very cheap antiseptic. 
It belongs to our best disinfectants, and is in general to be 
preferred to carbolic acid. I have examined creolin accord¬ 
ing to the following particulars: *
