The proportion which child- ren born deaf and dumb bear to those who be- come so after birth, is not very accurately known, and there is much difficulty in the way of ascer- taining this proportion with precision. It rarely happens that parents have observed anv defect in the hearing of their children until they are ex- pected to articulate. It is not improbable, there- fore, that in many instances where the disease is thought to be congenital, it may have commenced after birth, and the time of its commencement escaped the notice of the parents. The statistics which have been pubhshed by different institutions on the comparative numbers of those born deaf and dumb, and those who have become so afterwards, vary considerably. In a circular issued from the Dublin Institution, it is stated that in 489 deaf and dumb children, 423 were born so, the remaining sixty-six losing their hearing after birth, from various accidents and diseases. In the thirteenth Eeport of the Hartford (America) Asylum, it is said, that out of 279 pupils, ] 17 were born deaf and dumb, 135 lost their hearmg in infancy, and 28 were doubtful. These two statements differ consi- derably in the proportion which the two classes bear to each other, and though the induction, in both instances, is too limited to allow us to draw any general conclusion, still it is probable that](https://iiif.wellcomecollection.org/image/b20412484_0046.jp2/full/800%2C/0/default.jpg)
