One of the photo-micrographs created by Arthur E Smith and featured in the book Nature through Microscope & Camera (1909) by Richard Kerr. Little information is given about Arthur E Smith but we do know that the photographs featured in the book “were exhibited at the Royal Society’s Annual Conversazione, May 13, 1904”, so Kerr tells us in the opening chapter, and “done on 12 by 10 plates directly through the microscope and camera combined as one instrument” with the negatives receiving “no ‘touching-up’ whatever.” (Image Source: California Digital Library, via Internet Archive)
