To quickly assess the difficulty of the text, read a short excerpt:
The gland is so diminutive in size, so difficult to reach, so impossible, successfully to vivisect, if we may use the term, that little has been learned of its functional character. The only other method of learning something about it, is by post-mortems. But even this field is wonderfully barren. We have been unable to add to the two cases reported by Tafel. One was that of a man in middle life, a simpleton who stammered. The cerebrum was found to be white and compact like curd, the col- losum... a little hard and the gland shrunken to the size of a hemp seed. The other case was that of a virgin twenty years old, who, after six months of great suffering from pains in the head became blind, was gradually deprived of all her senses and died in great agony. The gland had grown to the size of a hen's egg and was petrified. Now, from what we know of rudimentary bodies in otlier animals, they possess no such facility of extreme contraction or expansion, nor are they permeated with follicles charged with an abundance of nerve matter and nerves.
