"_Nota quod quamvis Rogerius non designat inter glandulum et
testudinem, scias igitur quod testudo fit ex majori parte flegmatica,
minori melancholie, glandula vero a contrario_," a statement which
might readily suggest the suspicion that Gilbert had before his
eyes the text of Roland, or that, at least, he had not acquired his
knowledge of testudo from Roger, his usual surgical authority.

Gilbert's sections on goitre (_bocium gulae_)[8] are interesting in
themselves, and characteristic of the method adopted by him in his
discussion of surgical or semi-surgical subjects. An introduction
relative to the pathology of the disease and which seems to be
original, is followed by a treatment, medical and surgical, adopted
almost literally from the Chirurgia of Roger. Thus he says: "Goiter
occurs most commonly among the inhabitants of mountainous regions,
and is due to an amplification and dilatation of the veins, arteries
and nerves, together with the soft tissues, occasioned by the north
wind (_ventum boreale_), or some other confined wind, which during
childhood has accumulated in (_coadunabatur_) and enlarged the part
to the size of the goiter." After suggesting an analogy between the
disease and the redness and turgidity of the neck produced by passion
or in singing, he adds that some cases are due to an accumulation
of spongy tissue between the veins and arteries, or to the use of
flatulent food, and he even tells us that some old women know how to
produce and remove goitrous swellings by means of certain suitable
herbs known to them.
