The renowned Schnüffelpilz was much struck by the opinion originally entertained by Sir Joseph, that fleas and lobsters had an identical origin, and he was far from satisfied that the test adopted by the English naturalist was conclusive. So, as soon as he was installed in his new office, he commenced a series of experiments that extended over several years and were prosecuted with a perseverance and zeal characteristic of the great philosopher and worthy of his important subject. His patience and energy were amply rewarded by a discovery he made, which proved distinctly that the flea and the lobster were closely allied if not identical species.

His natural sagacity suggested to him, that if the identity of the two animals was to be established, it must be proved by the analogy of the anatomical structure of some portion of both animals which would be unaffected by the difference of the medium each usually inhabited. Careful consideration led him by a process of reasoning by exclusion to decide that the antennæ or feelers must be this organ. These, to a mind unexercised in the deepest profundities of comparative anatomy, would appear to be the most
