The second volume of Hartmann's Acute Diseases will appear very shortly.

We have nothing to mention in regard to the mode in which this work is to be used. It should be read and studied from beginning to end; that is all.

As this work is intended for practitioners generally, beginners as well as those who are more advanced in our practice, it may be proper to give a brief explanation of the various modes in which our medicines may be administered. We have nothing to say about the frequency or magnitude of the doses, as the reader will'find that subject fully explained and inquired into in the body of the work. All that we wish to do in this place, is to inform the beginner of the various modes in which the medicines may be given to the patient.

Administration of the pellets.-Two or three pellets may be placed upon the patient's tongue, taking care, however, that the mouth should be well washed previously. If the complaint should be of such a nature as will evidently require more than one dose of the medicine, the pellets, seven or eight in number, may be dissolved in half a tumblerful of water, turning the solution some twenty times from one tumbler into another one backwards and forwards; the tumblers should be well cleansed and dried before using them; nothing fuzzy should be left hanging about them. Never use the same tumbler for two different kinds of medicine. Let not the solution be exposed to the light, keep the tumblers covered, and use a separate spoon for each medicine.

Administration of powders. - If the patient should prefer taking the medicine in powders, use one drop of the medicine to about twenty or twenty-five powders; a powder should not weigh more than one grain.

Administration of the tinctures. - The tinctures should always be given in water, one or two drops in a tumblerful, stirring the solution well.

Administration of the lower triturations.-No trituration below the third should be given in water, but always in one-grain powders.

Hahnemann's favourite mode of administering the remedies was this: he dissolved a few pellets in a tumblerful of water, in the manner which has been indicated above, and then mixed a tablespoonful of that solution with another tumblerful of water, turning the solution twenty or thirty times from one tumbler into another backwards and forwards. This double mixing is very often required with the tinctures. A simple mixture of the tincture will frequently be found inefficient, whereas a doubly-mixed tincture has the best effect, provided the remedy is the true one.

Any medicine which is taken in water should be turned five or six times from one tumbler into another, previous to taking a new dose.
