Overview

Excerpt from Preliminary Outline of a New Classification of the Family Muricidae After examining and sketching the form of the radula, it will be necessary to tear the ribbon up so as to get separate rows and individual teeth, since they lie over one another like shingles on a roof. The whole of one tooth cannot always be seen under one focus, because the recurved cu3ps of the teeth are higher than the base. When the teeth are very transparent, it will be found necessary to stain the radula. To do this, first carefully clean the radula, then put it in a drop of strong solution of chromic acid; this stains it yellowish brown. It may then be mounted tempo rarily in glycerine jelly, or permanently in Canada balsam. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
