They com-municate with the right and left nasal passages respectively, along whichthe air enters and leaves the lungs in the act of breathing. In conse-quence of the long and pendulous condition of the soft palate (fig. 5), whichshuts off the mouth from the windpipe, respiration in the horse can onlytake place through the nostrils. The.se orifices and the passages intowdiich they lead are very capacious. Around the former are scattereda few long coarse hairs, the roots of which are connected with nerves ofsensation. Like the hairs of the lips, they play the part of feelers . Itfrequently happens, however, in our better-bred horses, that these tactileorgans are removed as a part of the equine toilet. If the nostrils beopened (fig. 7) by drawing apart their edges, or, as they are technicallytermed, alse, with the thumb and finger, there will be found, in addition

Its use is not well understood, but it would appear to be the remains ofan organ once essential in theeconomy of the primitive horse,but now probably of little phy-siological importance. At thetime this observation is being-made, an opening, al^out thediameter of a hemp - seed(c, fig. 7), may lie noticed atthe point of junction of theinfolded skin and the mucousmembrane. This is the orificeby which the tears or super-fluous moisture escapes fromthe eyes, from which it iscarried by a long narrow tubetermed the nasal duct. Whenseen for the first time it has been regarded by some as a
