SEPARATELY ISSUED PUBLICATIONS. For various reasons papers have been published on a variety of professional, scientific, or historical subjects in separate form and without serial number. They are here listed from the beginning, in the order of their issue. Only a few of these have also been printed in the Annual Reports. They are special publications without a serial number. These publications vary greatly in sizes and style of printing, the form being determined largely by the purpose they are intended to serve. Some of them, such as tables, etc., are printed on cardboard for use in the field; and others, such as star catalogues, larger in size, are printed and substantially bound with reference to similar use. 1850.
