The Secrets of Specialists/Chapter 32
Very often we find physicians who wish to have their prescriptions filled at a certain drug store, either because they think they have better drugs or else because they receive a percentage on prescriptions or perhaps they have an interest in the store. This has caused different secret systems of prescription writing to be introduced. The following very simple method has been used in some places and is a very convenient way to write prescriptions.
By the use of this system all medical ingredients are divided into grains, minims, and drachms. If the drug is a solid, it is designated either as grains or drachms, if a liquid, either minims or drachms. Grains and minims are distinguished from drachms by the position of the period. If the period appears at the right of the number, it either means grains or minims (1. one grain or minim); if at the left of the number, it signifies drachms (.1 one drachm). To illustrate, the following prescription will give symbols of both. ways of writing the same prescription:

For writing prescriptions in this way you should have special printed prescription blanks directing the patient to the pharmacy where it is to be filled or tell the patient that he can get it filled only at that certain store.
To the pharmacist who is not familiar with this way of writing prescriptions it is rather puzzling and some will refuse to fill the prescriptions altogether, while others will attempt to guess it out, which might act to the disadvantage of the prescriber.
