flights of pigeons, in the year 1832 ; by S. P. Hildreth. Be- 

 sides these, some of the shorter communications and notices,

 Anon.: Arcana of Science and Art; or, an Annual Register 

 of useful Inventions and Improvements ; abridged from the 

 Transactions of Public Societies, and from Scientific Jour- 

 nals, British and Foreign, of the past Year. Small 8vo, 

 with engravings. Sixth Year. London, Limbird, 1833. 

 The volume for the present year contains 312 pages; and, 

 of these, there are 111 on natural history, 35 of which are 

 taken, with acknowledgment, and 3 without acknowledgment, 

 from this Magazine. The frontispiece to this year's volume 

 is a portrait of Baron Cuvier. This work has been publicly 

 mentioned as " an encyclopaedia, to which the most eminent 

 of their time are constantly contributing : " it should rather 

 have been said, " into which the meritorious communications 

 made to, and published in, other works axe freely transferred." 

 The above-given eulogy has been copied into the " adver- 

 tisement" which is prefixed to the volume; but the copier, it 

 would seem, felt conscious of its liability to exception, for he 

 adds, " This opinion does justice to the value of the com- 

 munications, or materials." We give his last two words in 

 italics, to increase their significance. In the foot note to 

 p. 217.> for " Philosophical Magazine" read " The Magazine 

 of Natural History"

 This portion of his valuable contribution to systematic ento- 

 mology occupies 18 pages. — 39. Observations on Ignis

 and swamps. — 40. Observations on the influence of locality, 

 time of appearance, &c., on species and varieties of Butter- 

 flies; by J. C. Dale, Esq. M.A. F.L.S. &c. The species to
