The virtues of all these waters are nearly 
alike ; and the peculiarities of each will be 
easily understood by consulting the account 
given in the materia medica, of the sub- 
stance from which they are prepared. Mr. 
Hicholson mentions, that as rose-water is 
exceedingly apt to spoil, the apothecaries 
generally prepare it in small quantities at a 
time from the leaves, preserved by packing 
Class VIII. Oka Volatilia. Volatile 
Oils. 
These are prepared nearly in the same 
manner as distilled waters, except that less 
water is to be added. 
Seeds, and woody substances, are to be 
previously bruised, or rasped. The oil 
comes over with the water, arid is after- 
wards to be separated from it, according as 
it may be lighter than the water, and swim 
upon its surface, or heavier, and sink to the 
bottom. 
Besides, in preparing distilled waters and 
oils, it is to be observed, that the goodness 
of the subject, its texture, the season of the 
year, and similar causes, must give rise to 
so many differences, that no certain or 
general rule can be given to suit accurately 
each example. Hence, the following is the 
mode prescribed by the London College.
