and the eructation of gas may be interfered with so that chronic 

 bloating may be added to the suggestive, though by no means 

 diagnostic, symptoms. Equally obscure are the indications of 

 disease of the glands beneath the back bone and those above the 

 breast bone. Of the more superficial glands of the trunk the 

 following are the most easily examined : 



d. Glands in front of the shoulder blade. — This group is in front 

 of the middle of the shoulder blade, and may easily be siezed in 

 the hands in thin cattle. If enlarged unequally on the two sides, 

 or if very hard and nodular though small, suspicion may well 

 attach to them. It is only on rare occasions that they burst and 

 discharge. 



e. Glands above the stifle. — These placed on the side of the 

 flank in front of the stifle can also be grasped and examined. 

 Indeed, in certain animals, notably in the Channel Island breeds, 

 they can be seen by the eye. Swelling, inequality, hardness, nod- 

 ularity are the usual suspicious features. Often smaller pea-like 

 or hazel-nut-like masses are found scattered over the lateral walls 

 of the belly from the last rib to the hip bones, and even in the 

 interval between the two last ribs. 



/. External inquinal glands. — In the male the glands on the 

 sides of the scrotum, and in the female those on the sides of the 

 udder may be felt to be enlarged when affected with tuberculosis. 



g. The posterior cervical glands situated in the lower end of the 

 furrow that lodges the jugular vein, may be similarly implicated 

 and recognized. 



The deeper seated groups of lymphatic glands, need not be in- 

 dividually referred to, for though subject to tuberculosis they 

 rarely show as external swellings. Tubercles, however, may ap- 

 pear in any part of the skin. I have found a caseated mass like a 

 hickory nut on' the point of the shoulder, and fibrous warty-like 

 growths on the skin, and open unhealthy sores with hard fibrous 

 surroundings may be fibroid tubercle. 



It must be borne in mind that the lymphatic glands are liable to 

 become congested and inflamed from other sources of irritation in 

 themselves and in their vicinity so that the mere fact of disease of 

 these glands is no sufl&cient evidence of tuberculosis. It is how- 

 ever ground for grave suspicion, and further exculpatory evidence 

 is demanded.
