A lady of East Tennessee, who had suffered with constipation and feeble health for many years, was advised to drink water charged in yellow bottles. She wrote me that she was drinking water charged in yellow wine bottles, and asked me to send her bottles of the right shade of color, remarking as follows: “My bowels have been acted upon now five successive days. I am so delighted that I can scarcely wait the intervening time before receiving yours.” I had not then got my yellow chromo lenses ready, and so had to recommend the poor substitute of yellow bottles.
