for the larger and more numerous the spore collects of 

 mycoderma aceti are, the more dangerous the case." 

 c. Comparison of Kine Blood and Human Blood. 



1. The morphology of normal blood of kine exactly 

 corresponds with that of man as given above. 



2. The morphology of tuberculous blood in kine is not 

 the same as in man so far as these observations go. Dif- 

 ferences as follows : (a) Eed corpuscles act normally, 

 (b) Fibrin filaments are not massive and numerous. 



Similarities of kine tuberculous blood to that of man. 



(a) White corpuscles enlarged often more than in man. 



(b) The mycoderma aceti or vinegar yeast is present as in 

 man. 



Indeed it was on this yeast that I made the diagnoses 

 which were better than the average prognostications. 

 As noted, it occurs as single, double and multiple spores ; 

 in large snow-white masses of fusiform shape, sometimes 

 in large abundance just as in man. They are unmistakable, 

 positive. Have been found reliable evidence for many 

 years. 



IV. ADVANTAGES OF THIS BLOOD MORPHOLOGICAL TEST 

 OVER TUBERCULIN. 



1. It is simple, readily learned, easily applied. 



2. It introduces no diseased matter into the blood to 

 set up elforts to expel diseased tissues (not to stop causes), 

 which efforts of expulsion cause fever. 



3. It allows the diagnosis of the pretubercular stage 

 and the cure of the cattle; tuberculin is of no value ex- 

 cept when there is actual disease and breaking down of 

 the lungs. 



4. It does not involve the loss of the kine. 



5. It is always good so long as pre-tuberculosis or tuber- 

 culosis exists; and as in man, is of immense value in 

 making negative diagnoses when neither tuberculosis nor 

 pre-tuberculosis exist.
