Turkey opium. Opium, Meconium, Papaveris somniferi succus 

 spissatus. From the capsules of the white poppy by incision ; 

 but Miller thinks the Turkey opium is from a different plant, as 

 the capsule is not of the same shape : one of the principal instru- 

 ments of physicians ; anodyne, narcotic, gr. ss to gr. ij, or even 

 more, as the person is accustomed to its use or not, and also 

 according to the disease that is present ; so that it can only be 

 exhibited with due effect, or even with safety, by a person who is 

 not only skilful, but also acquainted with the constitutional habits 

 of the patient as to this drug ; some prefer a full dose at once, 

 others repeated small doses : it is thought to be anodyne, even 

 when used externally. The effect of opium taken improperly is 

 best obviated by a copious exhibition of lemon juice, with stimu- 

 lants, and the affusion of cold water on the head. Officinal pre-
