familiar as Magnolia or even Lobelia.) "The great i\|» use at- 

 tending the work requires that the price per part shall be $5.00," 

 say the publishers. We admire their courage in the enterprise, 

 and in aiming at the highest attainable excellence. There are 

 indications that their laudable endeavors will be responded to. 

 and that the time has ai length arrived '.'.hen a popular work of 

 this kind and in this style so "creditable to all concerned in it- 

 may be appreciated and sustained. a. g.

 Surveys, west of th> One-hundredth Meridian, in charge of First 

 Lieutenant Geo. M. Wiieelei:, under the direction of Brigadier 

 General A. A. Humphrevs, Chief of Engineers, U. S. A. Vol. V. 

 Zoology. Washington:" Government Printing Office. 4to, 1019 

 pp., with 45 plates. — This large and valuable volume is hand- 

 somely executed, and is in every way creditable to the officers 

 under whose direction it has been prepared, and to the several 

 naturalists who have contributed reports to it. The plates 

 are well executed, and several are colored (chromolithographs.) 

 Although this volume is dated 1875, and was doubtless then 

 printed, it appears not to have been actually published until the 

 hitter part of the summer or early in the autumn of 1876. It in- 

 cludes the following reports :
