been employed to cause resolution in indurated and thickened tendons, in 

 anchylosis of joints, and elephantiasis of horses and cattle ; also in swollen 

 and indurated glands, in large scars, lupjus, and keloid growths, and 

 corneal opacites. The value of the drug is still undetermined since re- 

 ports have been more or less at variance. 



Fibrolysin solution is probably best given intramuscularly into the 

 gluteals, but may also be injected intravenously or subcutaneously once 

 daily, or once every second or third day. 



Scarlet Red is a synthetic, non-toxic dye very valuable in 4 per cent, 

 ointment (with lard) in stimulating the growth of epithelium over slug- 

 gish wounds and ulcers, as in burns, gangrene, decubitus, and granulating 

 surfaces that formerly required skin grafting. It is not antiseptic.

 crystallizable, fatty acid; 4, cerylic alcohol. 



Dose.—H. & C, gii-iii, (60-90); D., 3ss-ii, (2-8). 



PEEPABATIOirS. 



Flwidextractum Eucalypti. Fluidextract of Eucalyptus. (U. S. P.)

Unguentum Eucalypti. (B. P.) 

 Oleum Eucalypti. Oil of Eucalyptus. (U. S. & B. P.)

 matic, somewhat camphoraceous odor, and a pungent, spicy, and cooling taste. 

 Spec. gr. 0.905 to 0.925. Soluble in all proportions in alcohol, carbon disulphide, 

 or glacial acetic acid.

Dose.—H,, 3i-ii, (4-8); D., Tltil-x, (.12-.6). 



Eucalyptol. Eucalyptol. CmHisO. (U. S. P.) 



An organic oxide (cineol) obtained from the volatile oil of Eucalyptus globu- 

 lus LabillardiSre (Fam. Myrtacese) and from other sources. 



Derivation. — Crude eucalyptol distills over from eucalyptus leaves at a tem- 

 perature varying from 888° to 352° F., and is purified by redistillation from 

 potassium hydrate or calcium chloride. 



Properties. — A colorless liquid, having a characteristic, aromatic and distinct- 

 ly camphoraceous odor, and a pungent, spicy and cooling taste. Spec. gr. 0.921
