    Measure—Three fluid ounces {or 85 c.c.) peppermint water; fifteen minims {or i c.c.) tincture of opium; two and a half drachms {pr'^'^ c.c.) aromatic spirit of ammonia. Household measures—Compare the teaspoons, dessertspoons and tablespoons with their equivalents in drachms and cubic centi- metres. Observe how greatly they vary from those equivalents. Count the number of drops required to measure one fluid drachm of each of the following :— Spirit of nitrous ether; tincture of ginger; tincture of digitalis; glycerin; simple syrup. In measuring, notice that the measure has graduation marks on the opposite sides; these must be in a line with each other and with the eye. The liquid will exhibit at its surface two lines—an upper and a lower one; it is the latter, forming the bottom of the meniscus, which is regarded as giving the true measure. Write with appropriate symbols the following quantities:—Thirty grains; two and a half scruples; half a pint; seven fluid ounces; two ounces; sixteen minims; four drachms; sixteen centigrammes; five and three-quarter grammes; twenty- two milligrammes; twenty - five cubic centimetres; nine and a quarter cubic centimetres.
