russian schools this summer for instance fifty pupils of the Ekaterin odar gymnasium will make a mountain trip of fifty days collecting natural history specimens an and d ethnographical data taking photographs to sketching and getting the physical benefits of life in the pine forests of the caucasus an extraordinary ease case is reported by efrench a french medical man named donilon Do Doul lot A man who had lost his right eye some years before white while still a child fell from a cherry tree his face striking upon a sharp stick in such a way that the nose the cheek and the left eye with the eyelids and the eyebrow were horribly mutilated the attendant surgeon believed the eyeball had been completely torn awa away y the pait pacient lent of course being left sightless A yeat yea afterward the man was surprised to td notice that he could distinguish daylight and the colors of floweth through his nose and hla his vision improved until he was able to see all objects below i though still insensible to light from I 1 above A simple explanation is found I 1 the blow falling obliquely upon the eyeball must have permitted the escape of the humors ofte eye and pierced the orbit but injuring the os particularly the retina on heating healing there must have haive remained in the bony boby case behind the closed lids a small opening putting the eye cavity in communication with the nasal flossae thus permitting the light to reach the retina through the nose it is pointed out that this served as an experimental proof of the theory axiom paring the retina to a daff darkroom room screen on which images of outside objects are formed even without refracting fr lenses when the light rays come through a very narrow op opening effing A british estimate is that ten
