INDEX TO SUBJECTS. 



To avoid overloading the Index tvith the names of the nuviei'ous animals whose bloods 

 were tested with precipitins it has been deemed advisable to exclude them. The names 

 will, however, be readily found by reference to the Tables on pp. 220-311, 364-380, where 

 they have been ordered zoologically. In the following Index the reader will find references 

 to the different bloods tested by looking up the Class or Order to which the animal belongs, 

 and in addition by referring to the Tables as follows :
