S7 England Finder Slide

S7 is a glass slide 75 mm x 26 mm marked over the top surface in a way that a referenced position can be directly read relative to the locating edges. It is marked with a square grid at 1 mm intervals. Each square contains a center ring bearing reference letters and numbers, the remainder of the square is subdivided into four segments numbered 1 to 4. Reference numbers run horizontally 1 to 75 and letters vertically A to Z (omitting I). The main locating edge is the bottom of the slide, which is used in conjunction with either the left or right vertical edge of the slide. Using the finder the position of a field of interest is easily recorded, ite can be relocated by another person when using a England Finder on another microscope. The location of the arrows is identical for all England Finder slides. Mark a label on the left hand side of the specimen slide, indicating the orientation. A total of 100 positions can be accurately located.
