    HENRY l.EE, CONSULTING SURGEON TO ST, (iKOKOE'iS HOSPITAL. IFi'oni Vol. LXIX. of the Medico Chirurgical Ti-fitisacf 10/1.1, published hy the Royal Medicnl and Chirurgical Societv of fon/7nn No satisfactory account has yet been given of the use of the tapetum lucidum, nor has its disposition in different animals been accurately described. The tapetum has generally been examined after the eye has been removed from its socket. It is then difficult to replace it in its exact natural position, and it has conse- quently been generally loosely described as irregularly placed at the back, or outer part of the back of the eye. In order to ascertain the exact position of the ta])etum, in its relation to surrounding parts, it should be examined in situ, before the eyeball is removed. For this purpose the upper part of the orbit may be taken away, leaving the eye in its natural position. The anterior part of the eye, includ- ing the iris, must also be removed, any colouring matter that may have escaped from the choroid must be washed out with a thin stream of water, and the retina, which becotaes opaque a few hours after death, must be removed
