ANXIOUS ONE.--We think that you will find the cause of your symptoms in your spectacles. Did you have your eyes examined by a medical man, or did you go to an oculist and choose the pair that suited you best? We guess that you did the latter, and if our surmise is correct, your symptoms are very easily accounted for. Your eyes evidently have different refractive powers, that is, they need different glasses. The spectacles kept by oculists, or, rather, opticians, have both glasses of equal power, so that you could not get a pair of spectacles to suit your own case unless you had them made for you. You say your "other eye is defective." By this do you mean that you cannot use that eye for working, or that it squints? In either case it would be practically useless, so that your "bad eye" has to do all the work, and is consequently overworked, becomes sore, and gives you headaches. If it is not exactly suited by the lens in front of it, it is quite capable of incapacitating you altogether. Go to an ophthalmic surgeon and get a prescription for glasses for each eye separately. Take the card to the best optician you know and have the glasses made for you. We know that this will be rather expensive, but it is necessary if you wish to keep your sight. AN OLD FRIEND OF THE "G.O.P."--We advise you not to use lemons for your hair, for though we do not think that they would do much harm, they are not likely to do any good. Try a hairwash of rosemary or quinine, or use a pomade containing cantharides. SLIGHT DEAFNESS (An answer to "JESSIE," "DEFFEE," "AN UNHAPPY ONE," "MINNIE STEWARD," and "QUEEN").--We are much pleased that our answer to "A CONSTANT READER" has been the cause of so many of our readers laying their troubles before us. As the five correspondents whom we are now answering have understood the absolute necessity of supplying us with information about their ills before we can give them a definite answer, and as all have answered the thirteen points which it is necessary to know before discussing the treatment of deafness, we will be able to give them much more lucid replies than is possible in most cases of the kind when correspondents merely ask us for "a cure for deafness."
