"May the 10th, 1836.—I am favoured with your letter of the 3rd instant, intimating that you had heard it reported that the benefit I had derived from your treatment of my eyes had disappeared. The only person with whom I have had any communication on the subject is my friend, Mr.——, whom I informed that the remedy was applied to my forehead and temples, by friction only, without your having prescribed or administered one grain of medicine, or having confined me to the house, or directed the slightest change in my former habits of living, either as to drink or diet; and that my sight was good enough to read, write, fish, shoot, and to see a pin on the floor at the most distant corner of an ordinary-sized room. What more can, or ought, a man of 67 years of age wish for in this respect? But if any are sceptical as to your mode of treatment, let them produce a testimony like this of a superior method.
"My dear Sir,
"Yours very faithfully,

Dr. Kent's Letter.
The only other case which I intend to quote, in order to show that the recoveries are lasting when the essential oils have been employed, is the case of Dr. Kent. This gentleman continues perfectly well. It is now nearly seven years since his recovery. He had, alternate days, rubbed upon his forehead and temples, with the friction sponge, the compound clove and pimento embrocation, quoted from page 136, on "Painful and Nervous Diseases."
