These boxes contain a group of accessories similar but not identical to the accessory boxes depicted in Richard Beck's A Treatise on the Construction, Proper use, and Capabilities of Smith, Beck and Beck's Achromatic Microscopes of 1865. Besides the differences in accessories, the accessories are arranged in a different order. In the 1865 accessory boxes, the drawtube is not in the accessory case, but housed separately in the main case for the microscope. Instead of a double nosepiece there is a quadruple nosepiece. There is also a second equilateral substage prism shown in the 1865 engraving in addition to the one supplied with this outfit, which is an Amici prisim for oblique lighting. There were spaces for four eyepieces in the accessory case of 1865. The 1865 outfit also had a lever compressor and a lister screw-type livebox-compressor as well as an additional large livebox. It appears that the nosepiece parabolic reflector included with this outfit was not included in the 1865 boxes.
*This type of Amici Microscope Prism should not be confused with other prisms associated with his name. These include the classic Amici prism for forming a direct vision spectroscope, and an inverting Roof Prism.
**The 'rings' referred to constitute the conoscopic or interference pattern of the crystal when viewed between crossed polarizers (polarizer and analyzer).
