Six tests were given to 112 individuals. The covariance matrix is given in this object.
The tests are described as
a non-verbal measure of general intelligence using Cattell's culture-fair test.
a picture-completion test
Bartholomew gives both covariance and correlation matrices, but these are inconsistent. Neither are in the original paper.
