Boy or Girl? Male or Female?

How much time does this thought occupy the mind of the expectant mother — above all in the East — and the minds of those around her!

A German scientist has invented the instrument that appears in the picture, by means of which the doctor can make certain whether the unborn child is male or female. This is done by directing the gaze through this examining instrument into the eyes of the expectant mother: if he finds the quantity of blood in the right pupil greater than in the left, the child is a male; and if it is greater in the left than in the right, the child is a female.
