On stertor, apoplexy, and the management of the apoplectic state . oesophagus. to its function in alimentation, the former is here animportant accessory to respiration and vocalization; andit hangs, as it were, in mid-air, ready to respond to themost delicate vibrations and other movements. I have been struck, in the course of my work, with thefact that, while much has been done with the comparativeanatomy of the adult mammalian larynx, but little attention I 114 EPIGLOTTIS OF LAMB. appears to have been paid to variations and dififerencesdue to age in any one case. In the course of my researchesinto the relative positions of the various parts concerned inthe production of stertorous breathing, I was early struckby the different forms of the epiglottis in many of mysubjects, and I ultimately found that this organ differs inshape and position in accordance with the age of the childor quadruped under investigation. In the sucking infantit is curled laterally upon itself, being very convex in frontand concave behind; while the rima glottidis is situated.

The glosso-epiglottidean folds are so disposedas to enclose, on either side, a valley, which lies at a lowerlevel than the glottis ; by virtue of the convexity of thefront face of the epiglottis, the liquid food of the sucklingis directed into the same, being thus prevented from enter-ing the larynx. The uvula, in the few cases which I have EPIGLOTTIS OF INFANT 115 examined, fits exactly into the excavated summit of theepiglottis, and the whole condition of the parts suggests anapproximation towards that so well known to be realizedin the developing marsupial while within the pouch. As the child ages, the epiglottis expands laterally, andpresents an almost plane surface towards the base of thetongue. At the same time the ri
