So much importance being attached to the structure of the hair, I made a collection from different individuals.

They were willing enough to let me have all the samples I wanted for a material consideration, of course, but the indifferent manner in which they pulled the hair from their heads, just as we should tear out hairs from the tail of a horse, convinced me that inferior races feel pain to a less extent than civilised man.

I once pulled six hairs at a time from the head of a sleeping child without disturbing it at all; I asked for more, and when twenty-three hairs were pulled out in one stroke, the child only scratched its head a little and slept on.
They are not so powerful at lifting as they are in carrying burdens.

Out of twelve natives, ten of whom were eighteen and twenty years old, while two owned to fifty years, five lifted a burden weighing 226 2/5 pounds (102 kilograms).

I was able to lift this myself.
