accurate; it is probable that they are not; but they are at least 
approximately correct, which is sufficient for my purpose. In 
classifying these contributions, probably no two persons would 
get exactly the same results,^ and I am quite sure that I should 
not get the same results in successive attempts. I avoided this 
difficulty very easily, however, by going over them but once. Re¬ 
membering the respect and interest with which man views his 
kind, I first divided the papers into those relating to man and 
those relating to the remainder of the universe. In the first 
or humanistic class there are 130 papers, in the second or 
naturalistic class, 155, or about 45 per cent and 55 per cent re¬ 
spectively. The humanistic class is quite heterogeneous, for in 
it are included such diverse subjects as literature, art, social 
and political science, engineering and anthropology. Social 
and political science with 56 papers is the largest division in 
this class or in either class. Man is so far a social being that 
the inter-relations of individuals in the society and the state oc¬ 
cupy much of his attention. The next largest division of this 
class is letters, with 39 papers. I must confess that I placed 
some papers in this division because I did not know where else 
to place them. I am glad that the writers will never 
know what disposition I made of their contributions in 
this classification. Hex t comes anthropology, with 25 
papers. The papers in this division have characteristics of 
both the humanistic and naturalistic classes and unite them. 
In this respect, engineering, with eight papers, is a cognate di¬ 
vision. The remaining division of the humanistic class is art, 
with two papers. In the naturalistic class, zoology is the 
largest division by a bare plurality of one, its close competitor 
being geology. In the earlier Transactions geology easily led, 
but of late years zoology has been creeping up, until now it has 
49 papers to 48 in geology. In making these counts, I was 
struck by the irregular or remittent growth in the number of 
papers in a given division Sometimes they would increase 
rapidly, and then for a time remain almost stationary while 
another division would take a spurt. On examination, these 
periods of growth would usually be found to be due to the ac-
