    ( y^^^^^^- The Connection of the Nervous Centres of Animal and Organic Life. By John O'Reilly, M. D. Licentiate and Fellow of the Royal College of Surgeons in Ireland, Resident Fellow of the New York Academy of Medicine. It is generally admitted that the secretions from all glandular bodies, as well as the skin and mucus membrane, depend on the presence as well as the agency of the organic nerves: Acknowledging this to be true, it must be coafessed that it is just as difficult to trace nervous filaments in their structure as in the maternal or faetal vessels in the placenta. The deduction to be arrived at from the the observations just made, is, that if it were possible to remove every particle of the body with the exception of the substance of the organic nervous system, that the outline of the body would remain perfect, as well as a true delineation of all the viscera as well as the blood vessels and muscles. The retina is the termination or the expansion of the optic nerve. The optic nerve takes its origin from the corpus geniculatum externum and a white fasciculus sent from the nates. The pineal gland rests on the tubercula quadrigemina and is attached to the inner margins of the optic thalami by two bands of white cerebral j matter; in color and appearance it bears a strong resemblance to a ganglion belonging to the organic nervous system. The third nerve arises from the inner border of the crus cerebri • it is distributed to the lavator palpebrae and all the muscles attached to the eye ball with the exception of the superior oblique and external rectus, it com- municates by a small branch with the lenticular ganglion. The ganglion is an exceedingly small body; it sends several filaments to the iris, some of which are lost on the ciliary ligament. I am stating facts without entering into minuce particulars.
