of the possible presence of the disease. .Morse says: "At the 

 post-mortem examination you may have your suspi- 

 cions strengthened by ilncHng hvcr. si)leen. intestines 

 and membrane uniting the intestinal folds ( niesentcries) 

 studded with \cllM\vi^ll white cheesy nodules of various 

 sizes."" Outside of the bacteriological test these post-mortem 



findings are the best 



proof of the disease we 

 have. The liver is af- 

 fected in nearly every 

 case of fowl tubercu- 

 losis. However, as has 

 been pointed out many 

 times in these pages, a 

 spotted condition of 

 the liver is no sure sign 

 of tuberculosis. Most 

 of the other li\er dis- 

 eases of fowls cause a 

 simple blotching of the 

 tissue in which the 

 center of each sjiot is 

 usually depressed or 

 at least only slightly 

 raised. (Cf. Fig. i, p. 

 54). In tuberculosis 

 the liver is covered 

 with numerous raised nodules varying greatly in number and 

 size as shown in tig. 3. A section of the liver shows these 

 nodules or tuliercles distributed throughout the tissue. 



Still more conclusive evidence is
