Excerpt from Practical Photo-Micrography In the following pages an attempt has been made to sot out the methods of obtaining photographs of microscopic objects. It is not an easy matter to describe the details and processes of a practical scientific subject in a lucid and interesting manner: it is one tiling to be conversant with the practical side of the subject, but quite another to write such a description of the procedure as will enable another person to carry it out. In the present instance all that is claimed is that the attempt is a straightforward one, founded on practical experience. The description of instruments is as full as the circumstances would appear to justify; that, for instance, of the microscope, about which much can be learned from books on pure microscopy, is less full than the description of cameras and their construction. The number of references to the work of others is small: not because the writer wishes in any way to pass over such work or to minimise its importance, but because the subject is one that is best treated in the light of personal experience. Sincere thanks are due to Professor R. T. Hewlett, who, in addition to reading the proofs and making valuable suggestions thereon, has at all times given advice, and placed at the author's disposal the benefit of his wide experience. Thanks are also due to Hr. F. Shillington Scales, M. A.; and to Mr. G. Beilby, F. R. S., and Mr. C. O. Bannister for the loan of blocks and specimens.
