"Percy F - a well-grown lad, aged 14I has always been a bright and intelligent boy, quick at games, and in no way inferior to others of his age. His great difficulty has been - and is now - his ability to learn to read.
This inability is so remarkable, and so pronounced, that I have no doubt it is due to some congenital defect. He has been at school or under tutors since he was seven years old, and the greatest efforts have been made to teach him to read, but, in spite of his laborious and persistent training, he can only with difficulty spell out words of one syllable.The following is the result of an examination I made a short time since. He knows all his letters, and can write them and read them. In writing from dictation he comes to grief over any but the simplest words. For instance, I dictated the following sentence: 'Now you watch me while I spin it.' He wrote: 'Now you word me wale I spin if'; and again 'Carefully winding the string round the peg' was written: 'Calfuly winder the sturng rond the Pag.'
