se solutions in
the proportion of 1 to 500, or 1 to 1000.

This means that there will be one part of the drug, or of the liquid
medicine, to 500, or 1000 parts of water. For example if you were asked
to make up a solution of bichloride of mercury in the strength of 1 to
4000, you would use one ounce of bichloride of mercury to four thousand
ounces of water, or one grain of the mercury to four thousand drops of
water,--one grain being equivalent to one drop.

Sometimes solutions are made up on the percentage basis. For example, a
five per cent. solution of carbolic acid. In this case it would be
necessary to take five ounces of carbolic to one hundred ounces of
water, or five drops of carbolic to one hundred drops of water.
