Has been prescribed for syphilis.
The name of the patient is usually best omitted in venereal diseases.
The proper name is not used for the mercurial salt.
The content of a"saturated solution"often depends on the amount of effort put forth by the particular compounder.
The quantity is rather large for the dose, as decomposition may occur to some extent before the amount would be used.


While convenience or economy may dictate this style of prescription, the physician should avail himself of an early opportunity to test the dropper the patient is using or note the rapidity with which the liquid is disappearing.
Written instructions should be given as to time of taking, diluting, etc.
It is probably best to administer one hour before or two hours after meals and to have the patient take the medicine diluted with one-fourth glass of water and follow with a glass of milk.

Prescribed as a purgative for a child 2 years old suffering from intestinal indigestion.
The name and age of the patient should be given.
Mite is not in the genitive case.
A child cannot usually take capsules till 8 or 10 years of age.
The inscription is a Latin sentence; so Roman numerals should be used.
Attention is called to the advantage of using sugar of milk in administering calomel to children. It has an agreeable taste and, of course, is therapeutically inert. In this quantity sufficient bulk is given to the powder to facilitate handling. In administering calomel to a child it is usually considered best to give in the early part of the day and follow in two or three hours by castor oil. The active purging is over before bedtime or may be checked by a warm colon irrigation.

Ordered for a child 5 years old. when a diagnosis of roundworms had been made.
All glucosides, neutral principles, etc., have the genitive ending i.
Santonin, although sometimes prescribed recklessly, is rather a potent drug, and this dose is too large.
This should be prescribed with something to dilute and render more palatable.
It is probably wise to instruct that the above is not to be triturated, as the crystals of santonin are more apt to reach the lower intestinal tract than the powdered drug.


This should be followed by an active purgative, as a tablespoon-ful of castor oil. Many prefer to give the santonin and sugar of milk without the calomel and follow with a purgative later.
Written instructions should be left with the family as to diet, etc. The best time for administering the above is probably in the morning, so that it can be properly followed by the castor oil and then by the colon irrigation.

For typhoid fever, etc.
Salol is neither the official Latin nor the proper English name of the drug wanted.
It is usually best to express a quantity by its largest denomination.
It is probably inadvisable to prescribe salol alone in capsules.
It is not often advisable to order more than 5 grains of a substance to each capsule.
As the drug is almost odorless and tasteless, there is no objection to giving in powders. The size of the dose and the tendency to form concretions would militate against the use of capsules. If it is ordered in capsules it should be mixed with a small amount of some soluble powder, as milk sugar, to cause the disintegration of the lump resulting from packing in the capsules.

Prescribed for Mr. Smith, who complained that he was "bilious."
It should be specified that John Smith is an adult.
Hyoscyamus is not in the genitive case.
This preparation would have a very disagreeable taste and would be best administered in capsules. If patient could not take capsules, other agents should be selected.
Adjectives should follow nouns.

These capsules are best given so that the last will be at bedtime and a saline administered early the following morning.
It is claimed that the purgation from the above is accompanied by a minimum of discomfort.
As a rule it is particularly undesirable to give a mercurial purge in broken doses at long intervals during the day, as the patient may be unnecessarily given a day of considerable discomfort.
Note the use of the new official extract of oxgall.

Prescribed in the treatment of dropsy.

Squill is not the Latin name of the drug wanted.
Pulv. is here the abbreviation of the Latin for the adjective, powdered; so it should ,follow the noun.
The words pill and every in the directions are obviously unnecessary.

This is given here more to illustrate the old formula than to recommend it.
This is certainly more desirable in capsules.
Hyoscyamus is frequently omitted from this combination, but its use to limit intestinal discomfort, etc., seems to be well founded.
Even if it is desired to continue this treatment for some time, the first prescription should be for a small amount, as it is frequently not well tolerated.
Prescribed for a case of menorrhagia.

The abbreviation gr. stands for both the singular and the plural.
