Naltunne Tunne Measures.

 he obtained the following units of measurement from Alex. Ross, 

 the chief of the Naltunne tunne, an Athapascan people: — 



I. The double arm's length, from the meeting of the tips of the 

 thumb and forefinger of one hand to the meeting of the tips of 

 the thumb and forefinger of the other hand. 



3. Single arm's length, " one arm," extending from the tip of 

 the middle finger along the extended arm to the shoulder- joint. 



3. From the middle of the sternum along the extended arnt to 

 the meeting of the tips of the thumb and index finger. 



4. From the inner angle of the elbow to the meeting of the tips 

 of the thumb and index finger. 



5. From the middle of the fore-arm to the meeting of the tips 

 of the thumb and index finger. 



6. From the first wrinkle of the wrist to the meeting of the tips 

 of the thumb and index finger. 



7. The width of the hand (when grasping a stick), " one grasp," 

 equal to the width of four fingers (No. 11). 



8. One finger width. 9. Two finger widths. 10. Three finger

 the extended left arm.

BOOK-REVIEWS. 



Elementary Text-Book of Entomology. By W. F. Kirby. Sec- 

 ond Edition. Revised and augmented. 111. New York, 

 Macmillan & Co. 281 p. 8°. $3. 

 Entomologists everywhere will welcome with pleasure this 

 new edition of Kirby's handbook of I'eference to the study of in- 

 sects. As compared with the first edition of the work, we find 

 the present one improved by the addition of a carefully prepared 

 index, and by an appendix and table of contents. The appendix 

 adds considerable new and valuable matter, while the last-named 

 feature answers admirably to present the main divisions of the 

 classification of insects used by the author. Various schemes of 

 the latter are briefly discussed in the introduction, but our space 

 will only admit of our saying here that seven orders are adopted 

 to which the lesser groups of all insects are referred. These are 

 the Coleoptera (including Strepsitera), Orthoptera (including 

 EuplexOfjtera and Dictyoptera), Neuroptera (including Trichoptera, 

 Thysanura, Collemhola, Mallophaga, and Thysanoptera), Hymen- 

 optera, Lepidoptera, Hemiptera or Rhynchota (including the sub- 

 orders Hemiptera — Hetero2)tera and Hemiptera — Hemoptera, 

 and the Anoplura), and Diptera (including Aphanipiera and pos- 

 sibly Achreioptera). Our author tersely defines these several
