 however, these animals become familiarised, and we Tind it 

 necessary to intermit it, or have recourse to others of inferior 

 merit. 



The writers of the Edinburgh Medical Commentaries take 

 notice, that the decoction of cabbage-bark always excites vo- 

 miting. We find no such effect from it here, and may ac- 

 count for it, by their receiving it in a mouldy state. A sy- 

 rup, therefore, is given there with better effect. They ob- 

 serve, also, that it has a diuretic virtue, which we have not 

 taken notice of here. 



This bark purges pretty briskly, especially in powder, 

 thirty or forty grains working as well as jalap by stool ; but, 

 in this way, it does not seem to kill worms so well as in de- 

 coction. 



Five grains of the extract made a strong man sick, and 

 purged him several times ; but, by frequent use, he took ten 

 grains to produce at length the same effect. 



It must not be concealed that fatal accidents have happen- 

 ed from the imprudent administration of this bark, chiefly 

 from over-dosing the medicine. But this cannot detract from 

 the merit of the cabbage bark, since the best medicines, when 

 abused, become deleterious ; and even our best aliments, in 

 too great quantity, prove destructive. Upon the whole, the 

 cabbage-bark is a most valuable remedy, and I hope will be- 

 come an addition to the Materia Medica.
