vioeable. Here, likewise, the parts ■will be brought into contact 

 with each other, and pressed together, and union may be effected. 



The owner of the horse will find it his interest to apply to a 

 veterinary practitioner as soon as a case of inflamed vein occurs. 



Should the vein h" destroyed, the horse will not be irrepara- 

 bly injured, and perhapa at no great distance of time, scarcely 

 njured at all.* 



THE PALATE— (besumed). 



At the back of the palate (see Fig. 3), and attached to the 

 crescent-shapbd border of the palatine bone, is a dense membra- 

 nous curtain, called the velum palati, so arranged that the horse 

 can breathe through his nostrils alone, and in the act of vomiting, 

 the contents of the stomach are ejected the same way, and not 

 by the mouth. On this account it is, and on account of the struc- 

 ture of the entrance of the stomach, that the horse can with great 

 diSiculty be excited to vomit. 



THE LARYNX 



Is placed on the top of the windpipe (see 1, Fig. 3) and is the 

 inner guard of the lungs, if any injurious substance should pene- 

 trate so far ; it is the main protection against the passage of food 

 into the respiratory tubes, and it is at the same time the instru- 

 ment of voice. 



The Epiglottis (see 2, Fig. 3), is a heart-shaped cartilage, 

 placed at the extremity of the opening into the windpipe, with 

 its back opposed to the pharynx, so that when a. pellet of 

 food passes the pharynx in its way to the oesophagus, it presses 

 down the epiglottis, and by this means, as already described, 

 closes the aperture of the larynx, and prevents any food from 

 entering it. The food having passed over the epiglottis, from 



* JVote by Mr. Spooner. — This disease sometimes occurs when bleeding 

 has been performed witli the utmost care and skill 



The course of treatment which a considerable experience of the disease 

 bas induced us to adopt, is to avoid all setons, and dissecting out the vein, 

 and above all, caustic injection, which we have known to produce a fatal 

 result. First allay the superficial inflammation by cold applications, and 

 then blister the part, washing off the effects of the blister the following day, 

 and repeating it several times. The ointment of iodine may be alternated 

 with the blister to advantage. During this time, the horse's head should 

 be tied up to the rack, and he should be fed on such food as will not require 

 any considerable action of the jaws, such as bran mashes, scalded oats, car- 

 rots, and but very little hay. In a few weeks the swelling will become re- 

 duced, the blood ^nd new channels, and the horse will become as useful as 

 ever. We have never known this treatment to fail. In a few instances it 

 may be necessary to apply the iion to the edges of the wound, and use 

 other methods to stop bleeding.
