I have to strongly disagreethis sort science is about as accurate as much of the current climate science
Measuring skull size (of several symetrical points on the skull) and then multiplying by "weight factor" that was probably determined from hundreds (or thousands?) of autopsy measurements before and after brain removal. By the 1930's this sort of data would be extant and widely available. Brain mass could be determined based on a known strong correlation between certain skull measurements and the actual weight of the brain after removal. Similar measurements for other parts of the bodies and the resultant data are how coroners and forensic anthropologists can examine a skull or pelvis and state whether "female" or "male". Some of these anthropological "measurement ranges" can be strongly suggestive of ethnicity or geographical origin. Of course, the stuff in the image I posted is borderline "hokum".How is "brain weight" determined except by autopsy?
I wonder if both of those steering wheels were hooked up ?View attachment 738468
