The prevalent type in Laguna is the tall, light Malay blend. 
There has been considerable intermixture with Chinese, and

a Malay blend, but with the Indonesian B element very prominent. 
There has been less intermixture with foreign blood than in the

It must not be forgotten that the Otis scale is an intelligence 
scale. It is not a test of knowledge.

of the intelligence of university students and of mill operatives, 
in which he found the former superior, says:
