the other characters, compared with ^(s-d also show that the differences, although 
not so large as in H, are all quite significant, and indicate that, passing from 
asylum to asylum, the means vary very considerably. In other words, while some 
local groups are fair samples of the "general insane" population for one or more 
characters, the majority of them ai'e not fair samples. Individual asylum groups 
as a whole therefore cannot be said to form part of a " general insane " population 
of a homogeneous character. On the contrary, considered interlocally, asylum 
groups as a whole show great heterogeneity — greatest in the character H. An 
inspection of the table shows what has already been demonstrated regarding this 
character, its great variability from asylum to asylum. If the differences, grouped 
as already indicated, be arranged in the order of their frequency it is quite clear

that the homogeneity curve // = ^- er^'^ does not in the least fit the distribution,

as Diagrams X {A and B) show. The fi'equency at the mean approximates to a 
minimum instead of a maximum value. The diagrams and maps show, what 
the analysis clearly indicates, that there are really two very distinct groups, a 
high-headed or hypsicranial and a low-headed or chamaecranial one. 
Examining now the relative local differences intralocally, we can form an 
idea of the anthropometric character of each individual asylum. Take striking 
cases : Argyll males and females show macro-, platy-, and chamae-craniality ; they 
are therefore large sectioned, j)^ is large ; they are thus large-headed or macro- 
cephalic and they are tall-statured or megalomegithic. Viewing dolichocephaly as 
a defect of i, this is the only significant defect among the Argyll inmates. With 
the exception of {%), all these characteristics ai-e significant excesses from 
their respective means. Thus the Argyll group of inmates is the most significantly 
different. The group is a megalomeric one, most of its characters being megalo- 
metropic. By megalomeric is meant that the group possesses, on an average, 
greater magnitudes of the various characters measured than the general population 
of inmates. By megalometropic is meant that, in reference to the magnitude of 
any character, the value found is significatitly greater than the value of the 
corresponding constant with which it is compared; by micrometropic, that the 
value is significantly less ; and isometropic means that it is insignificantly different, 
with reference to the constant. Lenzie inmates show almost as great deviations 
as Argyll inmates do. The body of the table shows Lenzie to possess brachy- 
steno-chamaecranial inmates, small sectioned and short-statured. The group is a 
micromeric one, having magnitudes of the various charactei'S measured consider- 
ably smaller on an average than the general population, i.e. most of the characters 
are micrometropic. On the other hand. Paisley approximates to the general 
population in the magnitudes of its character means. Paisley males are slightly 
macrocranial, but distinctly dolichocephalic, their only distinguishing feature. 
Paisley females are hypsicranial. On the whole, the Paisley group is an isomeric 
one, the magnitudes of the characters of tiic group being mostly isometropic, or 
they are on the whole similar to the values found in the general population. Tlje
