Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Manual of North American Birds For those who are already familiar with the use of analytical keys in works on natural history such instructions would of course be quite super uous; but as some who possess the book may not have had pre vions experience with such keys, the following directions are given for their benefit: In the first place, it may be stated that the principle upon which the keys are constructed is that of dichotomous antithesis. That is, each character tested must conform to one or another phrase, there being only one alternative. Therefore, if the characters mentioned after a1 do not fit the bird in hand, everything following must be ignored until a2 is reached. Having found that the bird belongs to a1 or a2, as the case may be, then the immediately following 6' is to be tested, and so on until the ultimate division is reached and the bird identified.
