VI. Diphtheria and Influenza—Crossed Eyes

This is why I say that to approach the problem conscientiously, one must know all the details. When you become acquainted with the whole case, we can talk about it. I would be glad to do so. You do not know, for example, whether the four mute children were the older or the younger ones. It must definitely be established whether or not this tendency to bring forth mute children was later cured or whether it appeared only after the four speaking children were born, in which case, the reason would have to be discovered somewhere after the birth of the fourth child. So, we would first have to be familiar with all the factors.
