THE NATURALIST.

Castles, cathedrals, and churches, palaces, and parks, and architectural subjects generally, have occupied so many frontispiece pages of our recent numbers, that we have been induced to select the annexed cuts as a pleasant relief to this artificial monotony. They are Curiosities of Nature; and, in truth, more interesting than the proudest work of men's hands. Their economy is much more surprising than the most sumptuous production of art; and the intricacy and subtlety of its processes throw into the shade all the contrivances of social man: a few inquiries into their structure and habits will therefore prove entertaining to all classes of readers.
