"No. 8 Cow. A few tubercles in both lun^s and also 

 in mediastinal lymphatics." — Veterinarian report. 



" No. 9 Cow. Red corpuscles attempt uummulation. 

 One or two typical spore collects. No fibrin filaments. 

 Enlarged white corpuscles. Some segregate spores. 

 Not a typical case. Pretuberculoas." — E. Cutter. 



"No, 9 Cow. Had only a very few tuberculous nodules 

 in lungs, but quite large abscess in the udder." — Veteri- 

 narian report. 



"No. 10 Cow. One typical spore collect. Enlarged 

 white corpuscles. Abundant single and double spores, 

 tuberculous. Fibrin filaments not seen. No crowding 

 of red corpuscles. Indeed the behavior of the red cor- 

 puscles in all these kine, differs from the behavior of the 

 red corpuscles in man in tuberculosis. Also the fibrin 

 filamentation diff"ers. So far as these cases go, only the 

 spores and spore collects are visible and significant." — E. 

 Cutter, 



" No. 10 An old cow, was in life a doubtful case to me, 

 yet on post mortem showed much more tuberculosis than 

 I expected." — Veterinarian report. 



"At first study this may not appear so satisfactory to 

 you as it is: All the cases you called " pretubercular" 

 had tuberculous deposits in the lungs, but the satisfactory 

 part comes in when we compare your notes with the ex- 

 tent to which the animals were diseased." 



"Your No. 1. The bull you say was decidedly tuber- 

 culous, and he was. 



"No, 2 Was worse than your notes^ state. 



"No. 3 You say not decisive, and she had only a 

 pharyngeal abscess. 



"No. 4 Was not a bad case though well marked. 



"No. 5 You call doubtful and so she proved to be on 

 post mortem. 



"No. 6 Was not a bad case althousrh well marked.
