The electron microscope, its development, The electron microscope, its development, present performance and future possibilities . electronmicrosco00gabo Year: 1948 128 The Electron Microscope more. Even if electron bombardment should reduce the highly complex organic substances to a sort of carbon skeleton, the chemist may be able to reconstruct the original, as the palaeon- tologists have reconstructed extinct animals from their skeletons. But there are many simpler substances, in particular the metals and all the elements which, unless they are melted or vola- tilized, will never be destroyed by electron bombardment, however prolonged. How far can we hope to proceed in their exploration by the electron microscope? In particular, can we expect to see single atoms, and to what detail ? Let us for the moment abstract from the spherical aberration. However great the difficulties in the way of reducing it, they are of a technical order. But there are other limitations of a more absolute nature, inherent in the exploring agent, the electron, and in the object, the atom.
