"Prof. Dewar told me yesterday that you would be expecting me to talk about the Niagara Falls, and that you would be disappointed if I did not. I can only say that I cannot imagine why any such opinions should have been held, and I can only express regret if I am disappointing those present by taking up a different subject. However, I have this to say, that the present lecture does deal with some of the work that has been going on there, while it deals far more directly with submarine telegraphy. The next two will deal almost entirely with problems which have been cropping up in the work of utilising those great falls and distributing the power in the neighbourhood, so that I trust the course will not be altogether a disappointment to those who had expected a different one." Scottish electrical engineer, inventor and astronomer discusses insights learned about alternating currents during his 1891-1895 work as consulting engineer on the Niagara Falls hydroelectric scheme. ; Ex-Library; 98, iii, 3 ad pages.
