than what he afterwards prepared by boiling together sixty 
pounds of sulphur and nine pounds of washing soda in a small 
quantity of water, and then diluting this to 200 gallons of the 
dip. The crystals were used in the proportion of one pound to 
five gallons of water. 
Cooper Dip — This is one of the arsenic-sulphur dips. It is 
manufactured in England and is one of the leading dips upon 
the markets. It is sold as a fine yellow powder in paper pack- 
ages of about ten pounds weight. It mixes readily in either 
cold or warm water. 
Black Leaf Sheep Dip — Manufactured by The Louisville 
Spirit Cured Tobacco Company, Louisville, Ky. The manufac- 
turers claim this to be a pure and highly concentrated extract 
of tobacco. It mixes readily in cold or warm water, but the 
manufacturers recommend that it be used at 110 to 120 degrees. 
It is a pleasant dip to use in that it requires no stirring during 
the dipping and does not dry or chap the skin like the lime 
dips. 
Skahcura — Put out by The Skabcura Dip Company, Chicago, 
111. This, like the preceding, is a tobacco dip. A bottle con- 
taining enough of the dip for 100 gallons of water is claimed 
to be the extract from 200 pounds of tobacco stems. It mixes 
with great readiness in water, cold or hot, and is a pleasant 
dip to use. 
Zenolemn — Manufactured by The Zenner-Raymond Disin- 
fectant Company, Detroit, Mich. 
This dip, also the three succeeding ones, seem to be coal- 
tar dips. They are black, sirupy liquids, mixing without the 
slightest difficulty in cold or warm water and having a distinct 
tarry odor. When put in water they all fonn a white mixture 
(an emulsion) resembling milk. They are all recommended as 
disinfectants and washes for sores, and when put upon the skin 
leave the latter soft and oily with no disagreeable after effect, 
so that the men using these dips took pleasure in washing their 
hands in them to make them soft. 
Chloro-Naptholetim — Put out by The U. S. Manufacturing 
Company, ^linneapolis, Minn. Seems in all respects like the 
preceding except that when emulsified with water it does not 
form quite as white a mixture. 
QuihclVs Liquid Dip — Manufactured by Quibell Brothers, 
Newark, England. This dip seems in all respects like the ])re- 
ceding. 
Sulpho-Napthol — Manufactured by Sulpho-Napthol Company, 
Boston, Mass. I have had but a small quantity of this dip to
