The first solution cannot be made in pure alcohol, because sugar of milk will not dissolve in alcohol. The first solution is therefore made in a mixture of half water and half alcohol.
To one grain of the medicinal powder triturated to the millionfold potency I, fifty drops of distilled water are dropped in and by turning the vial a few times round on its axis it is easily dissolved, when fifty drops of good alcohol * are added, and the vial, which ought only to be filled to two-thirds of its capacity by the mixture, ought to be stoppered and shaken twice (i.e. with two down-strokes of the arm). It is marked with the name of the medicine and 1/100 I. One drop of this is added to ninety-nine or one hundred drops of pure alcohol, the stoppered vial is then shaken with two strokes of the arm and marked with the name of the medicine and designated 1/1000 I. One drop of this is added to ninety-nine or one hundred drops of pure alcohol, the corked vial is then shaken with two strokes of the arm and marked with the name of the medicine and II. The preparation of the higher potencies is then continued with two strokes of the arm** every time to the 1/100 II, 1/10000 II, III, etc., but to attain a simple uniformity in practice only the vials with the full numbers II, III, IV, V, etc., are used in practice, but the intermediate numbers are preserved in boxes or cases with their labels. Thus they will be protected from the effect of daylight.
(* For the fifty drops of water as well as for the fifty drops of alcohol a vial containing just that quantity may be used, so that we need not then count the drops, especially as drops of water are not easily counted when it flows from a vial, the mouth of which is not roughened by rubbing with sand.)
(It will be well to mark on the label that it has been shaken twice, together with the date.)
(** After many experiments and searching comparisons with the patients I have for several years preferred from conviction to give to the medicinal fluids which are to be elevated to higher potencies and at the same time to be rendered milder, only two shakes (with two strokes of the arm) instead of the ten shakes given by others, because the potentizing in the latter case by the repeated shaking passes far beyond the attenuation at every step (though this is one hundred fold); while yet the end striven for is to develop the medicinal powers only in the degree that the attenuation may reach the end aimed for: to moderate in some degree the strength of the medicine while its power of penetration is increased. The double shake also increases the quantity of the medicinal forces developed, like the tenfold shake, but not in as high a degree as the latter, so that its strength may, nevertheless, be kept down by the one hundred fold attenuation effected, and we thus obtain every time a weaker though somewhat more highly potentized and more penetrating medicine.)
(Instead of the fractional numbers 1/1000000 (I/I), 1/1000000000000 (I/II), etc., these degrees of dynamization are frequently so expressed that only the exponent showing how often one hundred has been multiplied into itself is expressed, thus, instead of 1, 100 (3); instead of I/II, 100 (6); instead of I, 100 (9); instead of 1/100 III 100 (10); instead of 1/10000 IX, 100 (29) and instead of decillion I/X, 100 (3), thus only the exponents as to the third, sixth, ninth, tenth, twenty-ninth and thirtieth potency, etc.)
As the shaking is only to take place through moderate strokes of the arm, the hand of which holds the vial, it is best to choose the vials just so large that they will be two-thirds filled with 100 drops of the attenuated medicine.
