He also sees in the larger number of eggs laid by game-birds a provision by a benevolent Providence for the joy of the sportsman and the delectation of the epicure. Next comes a man who assures us that the colors of eggs are due to the influence of their respective surroundings on the imagination of the hen birds&mdash;the old story of Jacob's little trick on Laban in the matter of young cattle. This school instances as an example the red blotches prevalent on the eggs of falcons, regarded by it as a record of the bloody experiences of the parents; but it does not explain why the equally rapacious owls produce pure white eggs, or the blood-thirsty skuas and shrikes lay greenish ones. Other equally fallacious theorizings might be noted.</p> <hr class="chap" /> <p><span class="pagenum"><SPAN name="Page_154" id="Page_154">[Pg 154]</SPAN></span></p> <table class="sp2 mc w50" title="TEA."> <tbody> <tr> <td colspan="3"><span class="ac w100 figcenter"> <SPAN name="i_021.jpg" id="i_021.jpg"> <ANTIMG style="width:100%" src="images/i_021.jpg" width="446" height="600" alt="" /></SPAN></span> </td> </tr> <tr> <td class="xx-smaller ac w30">FROM K&OElig;HLER'S MEDICINAL-PFLANZEN.<br/> 282</td> <td class="x-smaller ac w40">TEA.</td> <td class="xx-smaller ac w30">CHICAGO:<br/> A.
