Acts 28:6

When he should have swollen - Πιμπρασθαι , When he should have been inflamed: by means of an acrid poison introduced into the blood, it is soon coagulated; and, in consequence, the extremities of the vessels become obstructed, strong inflammation takes place, and all the parts become most painfully swollen. Lucan, ix. v. 791, gives a terrible account of this effect of the bite of a serpent: -

- illi rubor igneus ora

Succendit, tenditque cutem, pereunte figura

Miscens cuncta tumor jam toto corpore major:

Humanumque egressa modum super omnia membra

Efflatur sanies late tollente veneno.

Ipse latet penitus, congesto corpore mersus;
