Gompantivt.—Much more is known of the sounds emanat- ing from the lower animals than of the mechanisms by which they are produced. This applies, of course, especially to such sounds as are not pro- duced by external parts of the body, it being very difficult to investigate these experimental- ly or to observe the animal closely enough when produc- ing the various vocal effects naturally. AH our domestic mammals have a larynx, not as widely different from that of man as might be supposed from the feeble range of their vocal powers. T^re are structural differences in the htrynx of the domestic animals, some of which are more readUy appreciated by the eye than described. ,. * The false (superior) vocnl bands are rudimentary or wantr ing in many mammals, including the horse, ass, etc. In ruminants the hirynx is proportionately lU-developed; the glottis is short, the vocal bands rudimenUu-y, and the ven- tricles wanting. , The lamyx of the pig is peculiar in that the ventricles are deep, though their opening is only a narrow slit; there is^how- ever a large membranous sac below the epiglottis, which, acHngasaSonator, exphunsthe great intensity of the voice of this animal. , , , j_ a'^ The actual behavior of the vocal bands has been studi^ experimentally in the dog when growling, barking, etc. And, so far as it goes, this animal's mechanism of voioe-production Fio. »tero-l»tena view «f the lar- ynx of the horse (Otanvean). 1. epl- Slottin; % aryt
