It has, notwithstanding, enjoyed a steady sale; and if slow it is only what might be expected, when the special nature of the subject is taken into account with the little progress science had made in relation to it when the book was first published. The practical utility of the method and arrangement employed in this guide has been tested by its adoption in the Army Medical School for several years, and it has been found that, by its aid, even persons little acquainted with Micro-zoology and Phytology have very readily arrived at the nature and name of objects they had never seen before.
