MEDICAL MEMORANDA. 
On the Author's frst setting out for Persia, a Medical Friend obliged him with a fe to 
Memoranda for filing, and properly applying the contents of his Medicine Chest 
which notes having been highly serviceable to himself, he subjoins them here for the use 
of other Travellers. 
1. Ammonia Preparata ; Ammonice Carbonas. 
Salt of hartshorn ; 5 to 10 grs. in water: it is a cordial and stimulant. 
2. Antimonium Tartarisatum. 
Emetic tartar; 3 or 4 grs. dissolved in 4 oz. of water, and two table-spoonsful 
given every quarter of an hour till it operate: it opens the bowels at the same 
time. 
3. Calomel; Hydrargyri Submurias. 
5 to 10 grs. in a little sugar or jelly, or made into a pill with bread-flour, &c. 
4. Cerussa Acetata ; Acetas Plumbi. 
Sugar of lead : one drachm of sugar of lead, one tea-spoonful of vinegar, one ditto 
of brandy, and one pint of water, make goulard water. 
5. Extract. Colocynthidis Comp. 
Compound extract of colocynth; purgative; a full dose 20 or 30 grs., but it is 
better in smaller ones, as 6 or 8, joined with 3 to 5 grs. of calomel. 
6. Opium Purificatum. 
From gr. to 1 gr. is reckoned equal to 20 drops of laudanum. 
7. Opii Tinctura. 
Laudanum from 20 drops upwards: if given in too small a dose it creates fever 
and restlessness; and, therefore, if the first dose produces no calmness in 1^ to 2 
hours, an additional quantity should be given. It is almost always better to join 
with it some antimonial powder (2 to 4 grs.), or emetic tartar gr.), or ipecacuanha 
(2 or 3 grs.), or in a common saline draught.
