On the "doubtful & obscure" subject of marriage of cousins, CD believes, that judging from the analogy of animals, no direct evil would follow from their marriage. He would, however, expect the offspring of unrelated parents to be somewhat superior in size and vigour. The injury from the increase of any bad tendency common to the family seems to CD more to be feared than mere consanguinity; "the good effects of crossing distinct families I look at as great & undoubted".
Thanks for facts on inheritance
Thinks CST’s paper (C. S. Tomes 1874) about the enamel on the teeth of the armadillo is most remarkable.

At the suggestion of Crichton-Browne CD writes on behalf of his son George, who is making a study of marriages between first cousins and of their offspring to determine the proportion of the latter who may be among the insane, deaf and dumb, idiotic, blind etc. Is GES willing to ask his patients [at the Royal Albert Asylum] for the information relevant to this study?
