cipitation or cloudiness was obtained from the blood of the dog, 

 pig, ox and sheep. 



Several other instances of the medico-legal use of this test have 

 been reported unofficially. The official reports will probably be 

 published in the near future. While the reaction is not absolutely 

 a specific one, occurring as has been pointed out in certain other 

 animals, it seems to be reliable in distinguishing human blood from 

 the blood of those domestic or common mammalian animals whose 

 corpuscles most nearly resemble human bjood corpuscles. While, 

 therefore, it may not wholly replace studies of the size of cor- 

 puscles and differential counts of leucocytes to determine the per- 

 centage of different forms of granules, yet, as a method of medico- 

 legal differentiation, it is a powerful adjuvant and is undoubtedly 

 by far the most useful test at the present time. Some experiments 

 in the direction of agglutination of red blood corpuscles by serum 

 of immunized rabbits give promise that in the future this method 

 may supplement the method of precipitation. It is too early, how- 

 ever, to consider this method, which has certainly not as yet 

 reached the dignity of a practical procedure.
