Dr. Kerr's son and assistant, whom we then called "the young doctor," died a few years ago in Canada, over eighty years of age. No man could possibly have been more considerately kind, gentle, and tender-hearted. On one occasion, in 1841, when, in typhus fever, I was struggling for my life, he sat up with me for three whole consecutive nights, and brought me through. He ever kept himself abreast of the science of the day, and devoted his abilities and energies, _con amore_, to the benefitting of men's souls as well as their bodies. Another model village and country doctor, also an intimate friend of my parents, Dr. Campbell of Largs, I knew very well. Good, genial, and accomplished, he was a perfect gentleman, and equally at home dining with Sir Thomas Brisbane, or drinking a cup of tea at some old woman's kitchen fireside. He read the _Lancet_, and tried all new medicines, and repeatedly, when going to London, at his request I procured the most recent instruments for him. He was intimate with Dr. Chalmers, Lord Jeffrey, Lord Moncrieff, Lord Cardwell, etc. In telling me of experiments with Perkin's metallic tractors, and that the same results were obtained with wooden ones, showing the power of imagination, he gave me a recent curious illustration. He had lately had the old fashioned little panes of glass taken out of the windows of his house, and plate glass inserted. His mother, who did not know of the change, calling one afternoon, sat on an easy chair, close by the gable window, knitting. On suddenly looking round she said, "Oh John, I've been sitting all this time by an _open_ window," and forthwith she began to sneeze! She actually took cold, and even afterwards could scarcely be persuaded that it had _not_ been an open window, for she said she felt the cold! The doctor told me of an old maiden lady who consulted him, and who, when he prescribed in a general way, insisted on knowing exactly what ailed her. He said she was only slightly nervous, and would soon be all right. This did not at all please her, and she at once loudly protested--"Me nervous! There is not a nerve in my whole body!" A West India merchant, one of his patients whom I knew, he also told me, one day said to him, "Doctor, for forty years I never knew I had a stomach, and now I can think of nothing else!" At the cholera time Dr. Campbell was laid down by the disease. The fact spread like wildfire over the village, and, at once, prayer-meetings for his recovery were called by the public bellman, meetings of _all_ the different denominations, including the Roman Catholics (Dr. Campbell was a Free Church Elder), and there were truly heartfelt rejoicings in the whole district over his recovery.
