Dear Sir,—Among the many invalids that have visited the Waiwera (Hot Springs), perhaps there is not one who has derived more benefit in so short a time as myself; and I think it is a duty I owe to others who may be similarly situated to make my case known. When I went to the Springs I was suffering great pain;—could not walk, but had to be carried, and when laid down on the sofa at Waiwera, suffered such excruciating pain, that I had to get brandy and water to keep me from fainting. My knee was swollen to twice its usual size. After fourteen days' bathing and drinking the water, I recovered; got rid of the pain, and felt in every way as well as ever I was in my life, which has continued; and I feel sure when better known, the Waiwera (Hot Springs) will be highly appreciated, and great benefits will be derived from such valuable medicinal springs. I have refrained from giving a testimonial till now, fearing the rapid cure could not be lasting; but is is now six months since I was cured, and not the slightest symptoms of a return of the pain, in fact I never felt better.
