Publisher's Synopsis
Excerpt from Cancer and Its Treatment: Being the Bradshaw Lecture; Delivered Before the Royal College of Surgeons of England on December 1, 1904
Until recently our ideas of the infinitely small were limited to the atom; but the atom has been split up', and the bombardments witnessed within a Crookes tube are said to be due to the broken-up particles termed electrons, ' which in size are reputed to present as great a contrast to an ordinary bacterium as a bacillus does to the human body. Have we any proof that there are not organisms infinitely smaller than the smallest known micrococcus - organisms which may be ultra-microscopic, and which may be contained within the cells known as cancer cells, and be the true cause of their eccentricities? I had the privilege of seeing a microscope at the Royal Institution in April of this year which bids fair to give us a range of vision far beyond anything that Helmholtz conceived possible when he argued that from physical reasons it was impossible to construct a microscope which would give a large scale image; and experience has so far justified his conclusions that the best work has been done with magnification of from 400 to 500 diameters, yet I saw distinctly there Objects under a magnifying power of diameters. It will help the appreciation of this point to say that the eye of the house-?y, if depicted on the same scale as shown by the microscope in question, would be an object 24 feet long by I3 feet broad. This discovery will doubtless reveal much that was previously unknown, and possibly bring into view our quest, though as yet this is a mere anticipation.
