This canal brings the pharyngeal vault into relation with the cavity of the sella turcica. It is permanent in certain of the lower animals; in man rarely so. Rossi found it only on nine occasions in 3700 crania. The author examined the collection of skulls from the insane in the Psychiatric Institute of Reggio—1300 in number,—and found it in 12 cases, 9 being females and 3 males. Externally the foramen is situated from 1 to 2 mm. behind the posterior angle of the vomer, and internally opens into the lowest point of the depression of the sella turcica, generally in the middle line. The openings, which are usually circular, vary from 2½ mm. in diameter, and give passage to a vein. In 43 other skulls, there were openings corresponding in situation which communicated with the sphenoidal sinus. The author regards its relative frequency in the insane as another example of degeneracy.
