From what has been said, some might be led to suppose that even the 30th attenuation could never be obtained; and it certainly could not, if the whole quantity used at each attenuation was preserved and carried forward to the end of the process. A moment's consideration will make this evident. At first, one grain of the article, if it is a powder, is to be dynamized, or rubbed in a porcelain mortar with one hundred grains of sugar. This is the first attenuation. Then if it is intended to preserve the whole and carry it through to the end, this hundred grains must be mixed and dynamized with one hundred times as much, which would be ten thousand grains, or about ten pounds in weight; and this would be
