VACCINES : DIAGNOSTIC AND CURATIVE 119 



ophthalmic, intradermic, and endermic tests on certain 

 of the cases enumerated above. 



The ophthalmic test with concentrated human tuber- 

 culin was applied with the object of discovering if any 

 of the animals were tubercular. The reactions are 

 described as follows : 



Case III.: First test, "slight"; second test, "slight"; third test, 



negative. 

 Case V. : One test, " fairly distinct." 

 Case VI. : One test, " absolutely negative." 



Case VII. : First test, " pretty good " ; second test, " very well marked." 

 Case VIII. : First test, "extremely slight " ; second test, " slight." 

 Case XL : One test, " negative except for a trace of muco-pus." 

 Case XII. : One test, "fair." 

 Case XIII. : One test, " failed to provoke any." 

 Case XIV. : First test, "very feeble" ; second test, "distinct." 

 Case XVI. : First test, negative ; second test, negative ; third test, 



negative. 

 Case XVII. : One test, " no indication." 

 Case XVIII. : One test, " failed to produce any." 



The ophthalmic test with concentrated avian tuber- 

 culin gave the following reactions (the authors do not 

 state whether the tuberculin used for Case VIII. was 

 concentrated or not) : 



Case V, : One test, " very distinct." 

 Case VI. : One test, " no reaction whatever." 

 Case VII. : One test, " discharge of muco-pus." 

 Case VIII. : One test, "good reaction." 

 Case XI. : First test,i"no indication whatever" ; second test, 

 negative. 



Two intradermic tests were performed with con- 

 centrated avian tuberculin (Cases VII. and VIII.), and 

 two tests with avian tuberculin the concentration of 

 which is not definitely stated (Cases XI. and XVI.). 

 The reactions were as follows : 



Case VII. : One test, "only just an appreciable." 

 Case VIII. : One test, "quite negative." 

 Case XI. : One test, negative. 

 Case XVI. : One test, negative.
