pass, being nothing nioio than spaces in the connectivo tissue until 

 they reach the larger lymph vessels, which finally em])ty into lymph 

 ginnils. These lymph glands are structures so placed that the lymph 

 llowing toward the larger trunks passes through them, undergoing a 

 sort of filtration. From the fact of this arrangement lymph glands 

 are subject to inlhuumatory diseases in the vicinity of diseased struc- 

 tures, because infective material being conveyed in the lymph sti'cam 

 lodges in the glands and produces irritation. 



LOCAL INFLAMMATION AND ABSCESS OF LYMPHATIC GLANDS. 



Acute inthunmation id' tlie lymjih glands usually occurs in connec- 

 tion with some inflammatory process in the region from whicli its? 

 lym[ih is gathei'cd. Several or all of the glands in a cluster may 

 become atl'ected, as in strangles, nasal catarrh, or nasal gleet, diseased 

 or ulcerated teeth, the lymph glands between the branches of tho 

 lower jaw almost in\ariably become alVected, which may lead to sup- 

 puration or induration. Similar results obtain in other portions of 

 the body; in pneumonia the bronchial glands become affected; in 

 ]>haryngitis the postpharyngeal glands lying abo\o the trachea be- 

 come all'ected, etc. 



Si/mptom^'. — The glands swell and become painful to the touch, the 

 connective tissue surrounding them becomes involved, suppuration 

 usually takes place, antl one or more abscesses form. If the inllam- 

 nuition is of a milder tyi)e, resolution may take place and the swelling 

 recede, the exmlative material i>cing absorbed, and the gland restoicd 

 without the occurrence of suppuration. In the limbs a wlude chain 

 of the glands along the lymphatic vessels may become affected, as \u 

 farcy, phlebitis, or septic iM)isoning. 



Trcatnunt. — l'\>mentation with hot water ami the application of 

 camphorateil soap iininieut or camphorated oil may produce a revul- 

 sive action ami prcNcnt suppuration. If there is any indication of 

 abscess forming, poultices of linseed meal ami bran made into a jniste 

 with hot water should be apjdietl, or a mild blistering ointment 

 rubbed in over the swollen glaiul. As soon as fluctuation can be felt 

 a free opening must be n\ade f(U' the escape of the containeil pus. 

 The wound may subsequently be washed out with a solution of 

 chlorid of zinc. .'> grains to the ounce of water, three times a day. 



LYMPHANGITIS. 



Specilic inflanunation of the lymphatic structures usually affects 

 the hind legs; very seldom a fore leg. This disease is very sudden in 

 its attack, exceeilingly painful, accompanied by a high temperature 

 and great general disturbance.
