That the blood vessels of any group of mammals in general are subject to great variations is well known. Such minor variations as have been observed within any group have usually been ignored or at most, resolved to conform to the type. Using the rabbit as a basis of study in mammalian anatomy during the past two years the writer has had an opportunity to make some interesting observations on the variations of the carotid arteries. Of one hundred and fourteen specimens dissected in the laboratory, twenty-three, or about twenty per cent were found to differ from the usual condition described in the texts. Of these, eleven individuals possessed marked differences, as shown in the illustrations in figure 9, which are numbered 1 to 12.
