MERBURY SALICYLATE. First introduced in the 

 medical profession in 1881. it has of late years 

 found a gradually increasing field of application 

 and usefulness. It rarely, if ever, produces intest- 

 inal irritation, nor does it cause stomatitis, unless 

 taken in very large doses. Naturally it has found 

 its greatest field of usefulness in syphilitic cases; 

 internally, as an injection, and as acollyrium. For 

 topical application it is mixed with vaseline 10 

 to 30 grs. to one ounce of vaseline. Internally it is 

 given in pill form in doses of 1-5 grain three to 

 four times a day. It has found a wide application 

 in the diseases of the eye. 



METHYLAL. An etheral colorless liquid, readily 

 soluble in water, alcohol and fixed oils. As a hyp- 

 notic, fifteen to thirty minims. Externally as a local 

 anaesthetic in form of ointment or liniment, both of 

 which should be dispensed in tightly-stoppered ves- 

 sels, owing to the extremely volatile nature of 

 methylal. 



MOLLIN. An oleo-saponaceous ointment base, 

 white, of the consistency of lard; does not melt even 

 in the warmest climate. It may be easily washed 

 off the skin, whether in its pure state or mixed with 

 ichthyol, Peruvian balsam and the like. 



NAPHTHALINE. Colorless crystals possessing odor 

 of coal gas, insoluble in water, sparingly soluble 

 in alcohol and fixed oils, but readily soluble if heat- 

 ed with these solvents. Used internally for typhoid 

 fever; dose two to eight grains, and externally in 

 skin diseases. Also used to destroy moths and 

 other small insects. 



NAPHTHOLE. Occurs in crystalline' scales, insol- 

 uble in water, soluble in alcohol and fixed oils.
