Examination of fibres by electron microscopy.

The use of the electron microscope as a powerful instrument in the study of crystal structure, colloids, fibres, and bacteriological specimens has now become widely recognized. In an effort to obtain images of higher quality, an electron microscope using magnetic lenses was constructed in this laboratory during 1939-40. The writer’s work along this line was interrupted by war work from the summer of 1940 onward. In the spring of 1945 the University acquired a Type EMU (R.C.A.) instrument which has been used for a variety of studies in electron microscopy; the writer has taken a number of photographs of pulp fibres at high magnification.
