ever, must be conceded— stiUiugia is certainly not without activity. Now, 

 while it is not claimed to act specificaUy in syphiKs, the fact seems well es- 

 tablished that in certain cases, by stimulating the secretory functions, it 

 €xerts a very beneficial influence. The same may be said of its action in 

 scrofulous and cutaneous affections. It undoubtedly desei-ves more care- 

 ful examination than it has hitherto had, in order that its sphere of use- 

 fulness may be more accurately defined. 



URTICACE/E.

samara.

 a rough, Hght-gray bark and reddish wood. Leaves alternate, 4 to 8 

 inches long? ovate-oblong, taper-pointed, doubly serrate, rough above, soft-

Constituents.— The only important constituent of shppery elm bark is 



an abundance of mucilage. 



P?-epam<ions.— Mucilagoulmi— mucHage of elm.— United States Fhar- 

 macoposia. This is merely an infusion of the sliced bark in boiling water. 



3Iedical Properties and t^-es.- Slippery elm is demulcent and slightly 

 nutritious. It is used largely in acute inflammatory and febrile affections, 

 either alone or slightly acidulated with lemon-juice, and is one of the most 

 valuable agents of its cLiss, seldom or never deranging the stomach. Ex- 

 ternally it is often employed in the form of a poultice, being first gi-ound 

 or torn into shreds, and made into a mass of proper consistence with boil- 

 ing water. It has also been employed, in the form of tents, to dHate the 

 neck of the uterus and fistulous tracts.
