^ween the archeSj and near its attachment to the palate, where 
at is impeded by no obstacle. There the main force of the 
■stream of air is concentrated, by which all the middle part of the 
uvula sliding on itself, projects beyond the isthmus Jaueium ; 
and as soon as its margins come in contact with either, with the 
tongue below, or laterally with the palatal arches, it will form 
a sort of sac, inflated and distended, which is the substance that 
appears under the form of a bladder. If the actiofi of the air 
continue, and the uvula be impelled forward, and the sac be in- 
flated and mcrease, some portions of the margins of the uvula 
will be at length detached from the arches of the palate and the 
tongue ; and hence the air will find a free exit ; the bladder al- 
ready formed, and until that moment most turgid, will instantly 
empty itself, and be converted into a membranous body, wrink- 
led and reddish, which the dromedary, as we have already 
stated, retracts within his fauces. 
It is only during the rutting season that the dromedary pro- 
jects the bladder. At other seasons of the year, by irritating 
him much and making him neigh, one may perceive in the in- 
terior of his mouth the swollen uvula rise up ; but at that period 
it never distends itself sufficiently to appear externally. . At 
that time the uvula is corrugated and shorter, and does not hang 
loose and relaxed bn the base of the tongue ; probably by rea- 
son of a contraction of the a%ygos muscle, and perhaps of some 
fibres of the levator es palati wtollis that are distributed over it. 
Even in the season, of love, it is only, as I have hinted above, 
in the moment of the venereal furor that the enormous uvula is- 
sues from the mouth, *, probably because it is only at that mo- 
ment that the uvula is wholly relaxed, and becomes capable of 
entirely shutting up the space between the anterior arches of the 
palate. 
It may be readily believed, that the uvula could remain in 
that state but temporarily, and for a short time, when it is con- 
sidered, that, even in the rutting season, the dromedary rumi- 
nates ; and that it is absolutely impossible for food to pass into 
the throat, as long as the uvula, relaxed . and pendulous, closes 
up the entrance. 
We see, then, that there exists in the dromedary an intimate 
connection between the organs of generation and the uvula ; and
