Dear Mr Wallace²,

I am indebted to you for helpful criticism. It is quite true that the palato-cerebral ratio³ is not an exact index of mental — or even cerebral — development — but it is, I think — as good an indication of human status as is available now. No: both the measurements on pp [pages] 380-381 are right: the lower molars are always longer than the upper molars[.]

Yours very truly | Arthur Keith² [signature]
