Ithaca, N. Y. Andrus & Church 1886-7. First Edition. IV pages + blank leaf + 32 leaves (printed on verso) + blank leaf + 4 pages. 8vo (5 3/4 x 9 inches). Original thin printed card covers, stab stitched with glued on wrapper (plain spine panel. INSCRIBED twice, once on the front wrapper "W. H. Mills, Mar. 9, '87 from the author" and a second time on the recto of the single front blank flyleaf: "Dr. W. H. Mills compliments - Simon H. Gage". Some rectos have additional illustrations and text segments pasted on. One of the additional illustrations pasted on may be a cyanotype. The others appear to be reproductions of hand-drawn illustrations, process unknown. Some pencilled notations and some edge tears (mostly marginal on the top edge). The last 4 pages are an offprint (reprint) of "Microscopical Notes" originally printed in "The Microscope, December 1886" Very Good. Wraps. 
The preface states "The following notes on microscopical methods take the place of those published in 1881. They are designed to accompany the Notes on Histological Methods printed last year, and to give only the main facts and principles relating to the microscope and to its manipulation which seem to the writer indespensable for the successful study of elementary histology. Simon G. Gage, Anatomical Laboratory of Cornell University, January, 1887".
OCLC 14781183 suggests the following concerning editions of this work: "Title varies: 1st-2d eds., Notes on microscopical methods; 3d-6th eds., The microscope and microscopical methods. 3d-4th eds. issued as pt. 1 of the author's The microscope and histology./ 6th, 8th-9th eds.: Author's autograph presentation copy" This agrees with the editions we've had over the years.
Austin & Blankenhorn's Preliminary Checklist of Microscopes and Microscopy lists 14 titles by Gage but not this one. Quite scarce in the marketplace. This is the first copy we've handled, and also the first example we've seen INSCRIBED.
