His work was re-evaluated in 1978 by Stephen Jay Gould who used updated statistical analysis to find the skulls about equal among the five groups Morton identified. Gould also noted Morton selectively included or excluded specimens and rounded off data. His analysis was published in The Mismeasure of Man published in 1981 and revised with a new introduction in 1996.
After reading about Samuel Morton's skull-typing work, one possible impulse would be to hasten to the Biodiversity Heritage Library at Internet Archive to read online or download a copy of Crania Americana.
Though Morton's comparative study of the skulls of aboriginal peoples in North and South America is flawed science, at least there are stunning illustrations.
