FERRI IODIDUM.-Common Names: Ferrous Iodide, Iodide of Iron. Description.-Iodide of Iron is made from iron turnings, water and Iodine. It is a steel gray, semi-crystalline mass, and oxidizes upon exposure to the air. It may be prescribed in either of the following forms: SYRUPUS FERRI IODIDE.-Common Names: Syrup of Iodide of Iron, Syrup of Ferrous Iodide. Description-This syrup is of a pale green color when fresh, but by age changes to yellow, red or brown. It contains 10 per cent. of Iodide of Iron. Dose. -20 to 40 drops. Usual Dose.-2 to 20 drops, well diluted with water, after meals. FERRI IODIDUM SACCHARATUM. Common Names: Saccharated Ferrous Iodide, Saccharated Iodide of Iron. Description. This is a yellowish-white powder, containing 20 per cent. of the Iodide of Iron, preserved by sugar of milk. It dissolves in seven parts of water, forming a clear solution. Dose.-1 to 10 grains, after meals. Indications.-Debility, with a soft and a relaxed condition of the muscular system; bloodless appearance of the surface; prostration of the system in secondary syphillis; scrofulous and other cachetic conditions; glandular affections; atonic amenorrhoea and leucorrhoea; syphilitic ulcers; atonic and chlorotic states of the system; tabes mesenterica. FERRI LACTAS.-Common Names: Lactate of Iron, Ferrous Lactate. Description.-This salt is in the form of granular crystalline mass of a sweetish taste. On exposure to air it absorbs oxygen and becomes Ferric Lactate, It is soluble in forty-eight parts of cold water and in twelve parts of boiling water. Dose.-5 to 20 grains. Usual Dose.-1 to 5 grains, in pill or powder, or recently prepared solution. Indications.-All cases requiring a mild, unirritating prepara tion of iron. FERRI PYROPHOSPHAS.-Common Name: Pyrophosphate of Iron. Description. This substance is a combination resulting as a precipitate when a cold solution of Pyrophosphate of Sodium is mixed with a solution of the Persulphate (tersulphate) of Iron. It is in scales of an apple-green color having a slightly-acid taste. The scales are freely soluble in water and in Glycerin, but not soluble in Alcohol. Sunlight decomposes it. This form of Iron is extensively used in elixirs. Doses. drachms. 2 to 10 grains; elixir, 1 to 2 drachms; syrup, I to 2 Usual Dose.-1 to 5 grains, in pills. Indications.-Cases requiring a chalybeate tonic. Leucorrhoea resulting from atonic conditions. This is one of the best and most-easily assimilated of the Iron preparations. FERRI SULPHAS. riol, Copperas. Common Names: Sulphate of Iron, Green Vit Description.This salt is in the form of crystals of a bluishgreen color. The crystalline powder is a pale-green color. It is odorless, has a styptic taste, and is freely soluble in water. It is insoluble in Alcohol. Dose.-1 to 3 grains. It is seldom used internally. Indications for the internal use of this agent are not here deemed necessary. It is extensively employed as a disinfectant. As a corrector of foul odors from cesspools, drains and vaults it is valuable. It may be used freely either in substance or in solutions. One pound dissolved in two quarts of water will disinfect five to ten cubic feet of the contents of vaults. Six drachms in eight ounces of water will disinfect the daily fecal discharges of one individual. LIQUOR FERRI SUB-SULPHATIS.--Common Name: Monsel's Solu tion. Description.- Monsel's Solution is a solution of the Sub-sulphate of Iron. The Sub-sulphate of Iron is intermediate between Ferrous Sulphate and Ferric Sulphate. It is of a dark brownishred color. When Monsel's Solution is placed in an open dish and exposed to the air near escaping steam, a light yellow mass results. This mass, when powdered, is known as Monsel's Salt. Indications. This solution, when applied to superficial bleeding wounds, stops the hemorrhage promptly and without producing the least pain. Coagulation of blood is instantaneously produced. It is useful in hemorrhages from the mouth, nose and throat, and also in profuse uterine hemorrhage. FERRUM REDUCTUM.-Common Name: Reduced Iron, or Iron by Hydrogen. Description. This is Iron reduced by heat and hydrogen. It is in the form of an extremely fine gray powder. The powder is soluble in warm diluted Hydrochloric Acid. Dose.-5 to 10 grains. Usual Dose.-1 to 5 grains. Indications.-Anæmic conditions caused by loss of blood or by severe fevers. FRASERA CAROLINIENSIS.- Common Name: American Columbo. Natural Order.-Gentianaceæ.

Both There are some points in the action of Cannabis Indica that seem to ally it with Ergot in some of its therapeutic uses. remedies are valuable in headache that can be traced to hyperemia of the cerebral mass; but Cannabis is particularly useful in head aches that accompany The dose in these cases In the sick-headache of females-an infirmity that is often associated with some menstrual irregularity-small doses, one or two minims, repeated every hour, a few hours before the expected attack, will often altogether abort it, or, failing this, very much mitigate the severity. In some forms of menorrhagia, particularly such as attend the change of life, Cannabis-in doses of 2 minims every hour of a good fluid extract, until some of the narcotic effects of the drug are lightly induced--often arrests the flow or lessens the profuseness, and as often relieves the patient of her otherwise more distressing nervous symptoms. The remedy is also of great value in the menorrhagia of younger persons. We have known ten drops of this fl. ex. arrest the flow so suddenly as to cause engorgement and pain of the uterus and ovaries. We have also found that adding small quantities of Ipecac to the Cannabis increases its action on the vaso motors. Cannabis is of some value in spinal engorgements, but the dose must be small. We have seen good results from it in these affections when given in one minim doses every 2 or 3 hours. We have seen the diarrhea of teething children checked by it in minute doses-- minim every half-hour. The remedy is far more successful in all the forms of neuralgia that have their cause laid in the ganglionic system of nerves than in the cerebro-spinal. In dysmenorrhea the drug has some reputation, but is hardly worth noting, inasmuch as it fails very frequently to relieve the suffering, unless the dose is carried up to the toxic range, then it does much after-injury. The quality of Cannabis as found in the drug stores is 99 in 100 times very inferior, in this respect resembling Egot; when of prime quality we have seldom been disappointed with it. Not many days ago we gave a lady a fluid drachm of Squibb's Extract, with orders to take one drop on a little sugar every half-hour till relieved of her excessive pain and wasting--she was in the grand climacteric of life, which has been attended for 6 months with almost a constant menorrhagia and pain in the pelvic organs, constant bearing down, frequent desire to micturate, loss of appetite, sleeplessness, and miserable feelings of utter prostration.
