156 THE ROYAL SOCIETY OF CANADA 
Case 22.—B’s first inquirer wished to know B’s denominational 
connection as between Protestant churches. The Russian consul, on 
the contrary, wished to know only B’s connection with the principal 
religious systems of the world; and the adherents of the Protestant 
system being classed as Lutherans in Russia, B declared himself a 
Lutheran, although his particular connection, as given to the previous 
inquirer, was with the Presbyterian Church. The answers were accord- 
ing to the degree of interest of the inquirers. 
Case 23.—The four accounts of B’s health were due in part to the 
degree of interest, but still more to a difference of interest among the 
inquirers. The inquiry of the first inquirer was more or less formal, 
and therefore his degree of interest was not as great as that of the 
remaining three. Between the second and third inquirers there was a 
difference of interest arising from the difference of interval—a year in 
the case of the second and only a month in the case of the third— 
since each of them had last received a report concerning B’ health. The 
interest of the fourth inquirer, who frequently took walks with B, was 
both different from that of the previous three inquirers and also much 
greater in degree. 
Case 24.—This is a case purely of degree of interest. To the 
members of the congregation it was immaterial whether all the choir 
or only four members of it sang the hymn; but the non-performing 
member had a natural interest in drawing the distinction and reported 
accordingly to the absent member of the choir, whose degree of interest 
was equal to his own. 
It will be noticed that Difference or Degree of Interest may operate 
in two directions, the one to the exclusion of general features and the 
other to the exclusion of particulars. Case 21 illustrates the exclusion 
of the general features, C and D not being interested in the general fact 
whether B had seen the physician M, but only as to whether he had 
done so with reference to the particular points in which respectively 
they were concerned. In Case 22 the interest of the Russian consul in 
B’s religion operates to the exclusion of particulars. In Case 23 the 
interest of the first and second inquirers concerning B’s health operates 
to the exclusion of particulars, and that of the third and fourth inquirers 
to the exclusion of the general features of B’s health. And in Case 24 
the interest of the members of the congregation operates to the exclusion 
of particulars concerning the performances of the choir.
