Excerpt from Sight and Hearing: How Preserved, and How Lost The author is duly grateful for the favor with which his book has been received. He is especially gratified with the many evi deuces continually afforded him that it has done and is doing good, by furnishing timely intimation of threatened danger, and by indi cating in what manner the eyes may be educated to usefulness in early life, and may be afterwards perpetually employed without injury. In looking back over the results of a quarter of a century, and to the experiences of greater and wiser men, the author is fully persuaded that, in relation to nearly every case of disease of the eye or ear, there was a time in its history when it could have been cured or prevented. If this book indicates to the careful reader when this point of time is reached, the author has accomplished his whole design.
