have entrusted the author with the type-specimens of Ispidina 

 ruficeps and Halqjon orientalis respectively, in order that his 

 plates might be drawn from them. We are glad to learn that 

 the encouragement with which Mr. Sharpe has met in the 

 course of the present work is such as to induce the hope that on 

 its conclusion he may set about another similar monograph. 



Captain F. W. Hutton^s paper " On the Mechanical Prin- 

 ciples involved in the Sailing Flight of the Albatros," printed in 

 the ' Philosophical Magazine ' for August last, was most kindly 

 forwarded by the author for insertion in this Journal, which, as 

 our readers will remember, was honoured by his former remarks 

 on the same subject (Ibis, 1865, pp. 294-298) — remarks which 

 have attracted considerable attention elsewhere. It appeared to 

 us, however, on examination of the paper, that our pages would 

 scarcely be a suitable vehicle for bi'inging to the notice of those 

 best qualified to deal with them investigations in a great mea- 

 sure purely mathematical. We therefore handed over the 

 manuscript to our more learned contemporary, who gladly 

 availed himself of it. On our part, it seems due to the author 

 that this fact should be stated, and we hope shortly to present 

 such of our readers as do not happen to be mathematicians, with 

 an intelligible abstract, not only of Captain Mutton's researches, 

 but also of those which have lately been carried on and illustrated 

 by most ingenious experiments by Professor Marey. 



Dr. Bowden, in his 'Naturalist in Norway'*, sneers at the 

 people of that country, because a work on its natural histoiy 

 "would not pay." As impartial judges we fear there is not 

 much credit due to the land in which such a book as Dr. 

 Bowden's could be published with profit. The author has but 

 the very slightest smattering of information respecting the zoo- 

 logical part of his subject, and has taken but few pains to learn
