it in the incubator for an bour it liquified and a suspension 
could then be made. The phenol and crude oil suspensions. 
were found to be less stable than those of the aldehydes. 
Small quantities gradually separated out after a day or two. 
Despite the difficulties encountered in making the aqueous 
suspensions their co-efficients were remarkably high as 
shown in the table (a) below:—

Kthyl alcohol was next tried asa solvent, but its co-effici-

alcohol has a co-efficiency of 1, i.e., equal to 1% carbolic 
acid.
