35. Dr. Avex. Low.—Processes of Growth in Infants. 
A preliminary study of the results of anthropometric examination of infants 
to discover how far sex, growth, and environment influence physical characters. 
Data pertaining to school children are available, but beyond records of weight 
and length at birth, data as regards children of pre-school age are very meagre. 
Our knowledge of growth as determined by the physical measurement of infants 
is mostly based on single measurements of groups of infants, so that there is 
no way of estimating the degree of variation in the same individuals at different 
periods of their growth. 
Five hundred and forty infants have been examined at birth, and detailed 
Measurements and individual histories recorded. An effort is being made to 
re-examine as many as possible at intervals of six months for at least two 
years. Re-examination is slow, and some years must elapse before sufficient 
remeasurements of the same individual children can be obtained to enable 
conclusions to be formulated.

Children, 
The observations were made on the Navajo Reservation in Arizona and at 
Albuquerque in New Mexico. Stature, sitting height, weight and age have 
been selected for special consideration. English school children have been used 
as a control. The methods used are of the simple biometric type, and special 
attention has been paid to the construction of Regression Coefficients and the 
comparison of observed and calculated results. 
The conclusions reached have been that at least for the earlier ages a good 
regression table calculated from a large number of English children (a number 
of which tables have now been published) works almost as well for the Indian 
children, if we take the mean values, as one calculated from observations on 
Indian children. The differences, especially in weight, are, however, of interest 
when a consideration is made of the different social and environmental condi- 
tions under which the children live.

38. Miss Isasen Gorpon.—Cultural Stability among the Mountain 
Whites of Tennessee. 
A study of the modifications in the life of an English-speaking community 
due to geographical isolation. 
The geographical and historical causes of this isolation were briefly described. 
The region was settled between one hundred and one hundred and forty years ago. 
The methods of agriculture, tanning of leather, spinning, weaving, cooking, &c., 
which the early settlers brought with them continued practically unchanged until 
very recent years. After a consideration of these and other aspects of the culture 
which have remained stable some of the changes which may be traced to isolation will 
be discussed.
