left picture covers the left-eye image of the right picture, to form — 
the binocular picture or scene; while homonymous images of — 
the right and left pictures are seen to the right and left. I have

and left pictures as seen by the rig ht eye, and r’ /’ the same as 
seen by the left eye. By careful St after what I have 
already said, the figures will explain themselves. It is true, 
this mode of representation is complex, and, for those unaccus- 
tomed to binocular experiments, perhaps ‘difficult to under- 
stand; but it has the advantage of truly representing the some- 
what complex visual phenomena.

and soon afterwards I obtained possession of this specimen by

size, weighing about 36 Ibs., which had come from the same 
county, and was exhibited along with some iron ores by Maj. 
Jed. Hotchkiss of Staunton. Learning sien me that t wane
