A SIMPLE EXPERIMENT TO DEMONSTRATE THE 
HIGH “ WETTING POWER" OF 
COOPER’S CATTLE DIP 
In consequence of the high degree of “wetting 
power" of Cooper’s Cattle Dip, it coats both animal 
and ticks with a uniform film of liquid poison, and does 
it with greater speed and thoroughness than any other 
dip. A very simple experiment will show how perfectly 
this “wetting power” is attained. 
Greasy book cover wetted with water. 
No uniform film—liquid has run together into drops 
and patches. 
Take one of those small black covered note books, 
the material of the cover of which is a kind of oil cloth, 
and therefore of a greasy nature; this will represent the 
skin of a beast, or the skin of a tick,
