STEREOSCOPE 



Stenophyllous (sten-of-il'-us) [gtevoc , narrow ; <j>'v?J/.ov, 

 a leaf]. In biology, possessing narrow leaves.

Stenosis (sten-o' '-sis) [rn-evoc, narrow]. Constriction 

 or narrowing of any pore, duct, vessel, or passage. S., 

 Aortic, a narrowing of the aortic orifice at the base of 

 the heart or a narrowing of the aorta itself. S., Cardiac, 

 as a consequence of inflammation of the connective tis- 

 sue in the myocardium, the conus arteriosus upon either 

 side of the heart may become diminished in diameter, 

 with consequent hindrance to the free passage of blood 

 from the ventricle into its corresponding artery. This 

 constitutes what is called stenosis of the heart. The 

 second sound is fully formed and sharply defined, thus 

 distinguishing the condition from valvular stenosis. S., 

 Cicatricial, stenosis due to a contracted cicatrix. S., 

 Granulation, narrowing caused by encroachment or 

 contraction of granulations. S., Mitral, stenosis of 

 left auriculo-ventricular orifice. S., Post-tracheot- 

 omy, stenosis after tracheotomy. S., Sub-aortic. See 

 S. , Aortic.

 that the differences between the various isomers are 

 due to the different positions of the same atoms or 

 radicles in tri-dimensional representations of the 

 molecules. Ordinary structural formula; involve only 

 two dimensions, length and breadth, but these are not 

 sufficient to explain numerous cases of isomerism now- 

 known, and a " spatial "or " solid " conception of the 

 molecule is necessary. The term allo-isomerism has 

 been proposed for these cases.
