1 The mode of preparing the medicines, which are to
2 form the external part of the lozenges. is similar to the
3 former. Thus—
4 For the first class of medicines, it will be sufficient to
5 take from 1 to 5 parts of sugar; for the second class,
6 sugar from 5 to 10 parts ; and for the third class, sugar
7 from 10 to 20 parts, to each part of the medicine ;
8 which, when sufficiently triturated, must be dissolved
9 by the addition of as much proof-spirit as may be
10 requisite to reduce the whole to a liquid sufficient to
11 moisten the lozenges (composed of sugar and starch)
12 when put into the mortar— 'Stirring them round, with
13 die spatula, until they hare absorbed the whole of the
14 liquid.
15 As already mentioned, animal substances easily undergo
16 decomposition ; and, on that account, like volatiles, are
17 better preserved in a liquid state—as a sugary essence—
18 which may be dropped on lozenges, or lumps of sugar,
19 just before administering them.
20 With respect to the administration of these remedies,
21 One lozenge constitutes a Dose, whether the patient be
22 an adult or an infant; as the medicine operates more
23 specifically than mechanically; for instance: a like
24 quantity of matter produces a like effect in the vac¬
25 cination of a babe and a giant. In acute eases, the dose
26 may be repeated hourly; in very urgent cases, even
27 fifteen minutes; in protracted cases, once or twice a dftv •
28 in chronic cases, every other day, and sometimes once
29 every third day.
30 If tin case be acute, as much medicine as is sufficient
31 for one day should be delivered ut a time (unless ne¬
32 cessity demand an alteration); if less urgent, sufficient
