Description1157 is a fine example of the type of compound microscope that Nachet et Fils called the "grand modèle." For descriptive purposes and better comparison with a similar but not identical, early "grand modèle" by Nachet, the assembly is divided into these components, each with their own images and written details:
1157a: the microscope with eyepieces
1157b: box of objectives and condensers
1157c: microscope case and parts box, with diverse accessories
1157d: box of slides
1157e: bull's eye condenser
1157f: Amici illuminating prism, Nachet-style
1157g: compressorium
1157h: microscope instructions, handwritten
1157i: owner's business card
-------------------------------------
1157h is a sheet of light blue paper with handwritten notes in brown ink. The notes are entitled, "Note sur le microscope."
The notes describe the use of the eyepiece micrometer and the camera lucida.
The reverse of the sheet is penciled, "Regler à observer."

ProvenanceDr. Algernon S. Coolidge, Sr, Harvard Medical School; Dr. Algernon S. Coolidge, Jr, Harvard Medical School; Dr. Edward D. Churchill, before 1940; gift to Ernst-Lewis Collection of Microscopes (inv. no. 157), Harvard Medical School, 1940.
Historical AttributesFormerly Ernst-Lewis collection no. 157.
Dr. Lewis notes: "From Dr. Edward D. Churchill in 1940. It came to him from the heirs of Dr. Algernon Coolidge, and possibly belonged to his father [Dr. Algernon Coolidge. Senior]. The brass trimmed mahogany box with full equipment was in its leather case. Since this microscope would have been out of date for Dr. Coolidge Jr. (AB 1881; MD 1886; Professor of Laryngology, 1911-1925), it in all probability belonged to his father, Algernon Coolidge, MD 1853, University Lecturer 2nd half 1867-1868, Instructor in Pathological Anatomy, 1865; Lecturer on Tumors, 1868-1869, in connection with which this microscope would have been excellent equipment."
