is required, it may be obtained by means of a nutmeg-grater (included in List in Appendix C), and subsequently triturating the rough powder thus obtained in a mortar till it is reduced to the state of a fine powder. In the preparation of a _Compound Powder_, _i.e._, a powder containing two or more ingredients, it is of the greatest importance that they should be uniformly and thoroughly incorporated, else it is evident that a small portion of it, such as is usually prescribed as a dose, may contain an excess of one ingredient—it may be an active or dangerous one, and operate powerfully—whilst the next dose may be comparatively inert. Powders, when prepared in large quantities, should be kept in well-stoppered or corked bottles; if left in open vessels exposed to the action of the air, they soon become deteriorated. _Pills._—For the reasons just stated, it is necessary, when two or more ingredients enter into the composition of a pill mass, to be careful that they are thoroughly incorporated. When powders, &c., enter into their composition, a little honey or _jaggery_ is the best thing to give them cohesion and consistence. They should be moderately hard; if too soft, they are apt to lose the globular form which they ought to possess, and become a shapeless mass. When several pills are made, a little Arrowroot or Rice Flour should be added to the box which contains them, to keep them from adhering to one another. No pill should ordinarily exceed 5 grains in weight, otherwise there will be a difficulty in swallowing it; two 3 grain pills are more easily taken than one of 6 grains. Pills, when prepared in any quantity, should, like powders, be kept in well-stoppered or corked bottles. _Ointments._—Animal fats, _e.g._, Lard, which is so generally used in English pharmacy, are apt to become rancid and irritating in hot climates; hence they should be discarded in tropical practice. In India there is another _cogent_ reason for _abandoning them_, viz., _the religious prejudices of the natives_, especially of the Mussulman, to whom hog's fat is _an abomination_. The only allowable animal fat in India is freshly prepared Ghee, or clarified butter; but this in the hotter part of India is of too thin consistence for ordinary ointments. Fortunately India supplies at least two vegetable substitutes, Kokum Butter and Piney Tallow (the expressed Oil of Vateria Indica). In addition to these, I have introduced a third article, Ceromel (a mixture of wax and honey). With these three agents it is believed that animal fats may be altogether dispensed with in Indian pharmacy.
