Rub each portion well together, pour into the vial and add:
- Sulphate of Iron one scruple,

I have often thought that if our formulæ, especially those that are complicated, were given in proper rotation, placing the component first to be used, first in the list, the second next, and so on, with intermediate lines of direction, which might be in smaller type or italics, it would derogate nothing from the dignity of the book, while it would facilitate the process, and might sometimes obviate misconstruction, or neglect of particulars essential to the best result.
The consideration of some few other preparations, I must defer to another number.
