204 CATTLE. 



extending from the styloid process of tlie occipital, to the angle of 

 the corner of the hyoid bone, and its action confined to the retracting 

 and elevating of the corner of that bone. 



14. A muscle of the larynx. 



15. The parotid gland, (the gland in the neighborhood of the ear,) 

 the greater part of it reversed, to show the parts benccitli. 



16. The parotid duct, winding within the angle of the jaw, and 

 escaping again at a very little distance, and in company with the 

 maxillary vein and artery climbing up the cheek, and perforating the 

 buccinator muscle, in order to discharge its contents into the mouth. 

 The orifice is generally found about the third or fourth grinder. The 

 situation of the duct should be carefully observed, for obstruction 

 and fistula of this duct is frequent in the ox, and operations of various 

 kinds may be necessary. 



IV. The submaxillary gland (the gland under the jaw). Its com- 

 mencement is almost as high as that of the parotid, but behind it ; 

 thence it reaches down to the angle of the jaw, and there begins to 

 take a direction forward between the branches of the lower jaw, and 

 terminates in a duct which opens on either side of the fraenum of the 

 tongue. 



18. LympJiatic glands (glands containing lymph) of the neck. 



19. Lymphatic glands found between the branches of the lower 

 jaw; neither belonging to the submaxillary nor sublingual glands, 

 but often confounded with them. They become inflamed and «»nlarged 

 in almost every case of catarrh. These glands often enlarge to a 

 very considerable degree, suppurate, and troublesome ulcers ensue. 



20. The jugular vein (the vein of the throat), previous to its 

 bifurcation, and pointing out the usual situation for bleeding. 



21. The submaxillary vein, returning the blood from the tongue, 

 the mouth, and the face generally. It is scarcely lost at all within 

 the angle of the lower jaw, but runs along the edge of it, and might 

 be opened with advantage in some affections of the face. When it 

 emerges from the jaw, and begins to climb up the face, it is found 

 between the parotid duct and the submaxillary arter3\ 



22. The larger branch of the juguhir above the bifurcation receiv- 

 ing the blood from the upper part of the face and neck, and also 

 from the brain. It is so near to the parotid gland, that it would be 

 difficult to bleed from it there. The bifurcation is sometimes com- 

 pletely covered by the parotid gland. We must therefore be always 

 content with bleeding below the division of the jugular in cattle. 



23. The temporal vein (the vein of the temple). 



24. The trunk of the parotidean and auricular veins (the veins of 

 the parotid gland and of the ear). 



25. The internal jugular, and particularly its passage below tlie 

 subscapulo-hyoideus muscle. The path of the internal jugular by 

 the side of the carotid^ under that muscle, is marked by a dotted line.
