Ponds Rock Pools - With Hints on Collecting for and the Management of the Micro-Aquarium #246586

The chapters contained in this book appeared originally in the pages of the Leisure Hour. They have been considerably enlarged and very carefully revised. In their original form they were purely scientific, and this form they retain unaltered in their new dress.<br><br>The Committee of the Religious Tract Society have for nearly a century past done all in their power to place within the reach of their readers accurate information on scientific and historical subjects no less than on those which are purely religious. But they exist mainly for the last named purpose, to preach in every possible way through the printing press the Gospel of Jesus Christ, 'the power of God unto salvation to every one that believeth.'
