Transcriber's Notes

All obvious typographical error were corrected. Due to variant usage of hyphens, "soft-shelled" and "crystal-clear" were used as the standard for variants of those terms. All other variant spellings of "softshell(s)" and where variant spellings occur in quoted text or literature titles they were retained. Variants in accented and non-accented words may exist. Paragraphs split by tables or illustrations were rejoined.
