“The Hound of the Baskervilles” in The Greatest Adventures of Sherlock Holmes has proved to have several very interesting words that I have not read before, or at least that I have not heard often. One of the main characters, Dr Mortimer, mentions this word when he first meets Sherlock Holmes.

Dolichocephalic – having a relatively long head with cephalic index of less than 75

(cephalic index – according to Merriam-Webster – is the ratio multiplied by 100 of the maximum breadth from side to side of the head to its maximum length from front to back in living individuals)

Usage by Dr Mortimer: “You interest me very much Mr Holmes. I had hardly expected so dolichocephalic a skull or such well-marked supra-orbital development.”
