Excerpt from The Structure and Function of Sponge Cells: New Criteria for the Taxonomy of Poecilosclerid Sponges (Demospongiae)In several cases the fixative employed for museum specimens was unknown. However, whatever the fixative was, these specimens (which are presently pre' served in alcohol) were in acceptable condition for cytological analysis. Thus, older material which is preserved in alcohol for long periods of time is still use ful for the type of analysis carried out here. Iron hematoxylin, pas, and toluidin blue staining can be carried out on this material, even in the absence of knowl edge of the original fixative employed. These stains allow a minimal cytological analysis which can be utilized for comparative purposes.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
