Notice of some of the Birds of Madeira. By C. HEINEKEN, M. D.—ZJbid, 
p. 229. 
1. Columba trocaz ne 
Dr. Heineken proposes the trivial name of “ Trocaz,” for a pigeon 
which he considers to be an undescribed species, belonging to the Co- 
lumbe antarctopodie of Wagler. Its characters are, ‘‘ Brownish ash $ 
head, neck, breast, vent and rump, ash; neck imbricated, and toge- 
ther with shoulders and breast iridescent ; belly vinous ; wing and tail 
feathers brown black, the latter with a broad blue ash bar one-third 
from the tips, which are black ; the outer web of the 2d, 3d, and 4th 
primary of the former, edged with white; bill red, tipped with black $ 
nails black ; legs red, feathered a little below the knee ; iris pale straw 
colour; length 19 inches ; tarsus one and a half inch. (Adnlt male in 
the spring. ) 
Ash ; head, neck, belly, and rump blue ash; neck only iridescent and 
imbricated : breast and shoulders vinous; length 18 inches; tarsus 
one and a half inch. (Adult female in the spring.)” 
2. Procellaria Anjinho. 
Sir W. Jarbiue is of opinion that this species is new. The characters: 
given by Dr. H. are :—“ Bill shorter than the head, and compressed- 
towards the tip; nostrils united in a single tube at the surface of the 
bill, but the septum distinctly seen a little within the orifice ; tail 
slightly forked, extremity of wings not surpassing it; plumage entire- 
ly brown black or soot colour; bill black ; legs smoky ; length 1] in- 
ches; tarsus Linch. (Adults taken in spring and summer.)” 
Some remarks on its habits are subjoined. 
Dr. H. notices a Cypselus, whose plumage was entirely black, and de- 
sires information as to the winter plumage of the C. murarius, which 
differs from this specimen in having a white chin. Sir W. Jardine pos- 
sesses both the C. murarius, and this black-chinned individual, which 
he thinks is a distinct species, and probably undescribed. 
- Dissertation sur l’emploi du Vinaigre a la guerre, comme agent de destruc- 
tion-et comme moyen de defense. Par M. Rey. 8vo. Paris 1829. 
Under a title certainly foreign to Geography, Mr. Rey examines a geo- 
graphical question which has occasioned long controversies,—the place 
of the passage of the Alps by Hannibal. He has had the ingenious idea 
of collecting, in a synoptical table, all the opinions which have been 
given, down to the present time, upon this interesting subject ; and, 
according to him, with the exception of errors or omissions, out of 90 
opinions, 33 are for the little St. Bernard, 24 for Mont Geneve, 19 for 
the great St. Bernard, 10 for Mont Cenis, 3 for Mont Viso, and-I for 
Rocke Melon, and probably the question is not yet decided. It may 
be observed, however, that Livy, and Polybius, whose texts still 
remain to be explained, ought not to have been found on the columns 
of this table. . 
Scandinavien und die Alpen, (Scandinavia and the Alps; with an Appendix — 
upon Iceland. By Victor de Bonstetten.) 8vo. Kiel 1828. 
This work offers a comparison of the Swiss Alps, and those of the north, 
in their geognostic relations. Along the whole length of the coast of 
Norway, for a distance of 1200 miles, granite rocks may be seen split 
to their very base, so that the eye can penetrate into precipices of 
more than 1000 feet in depth. . 
Tables for converting the Weights and Measures, hitherto in use in Great 
Britain, into those of the Imperial Standards. By Gro. BucHaNnan, Civil 
Engineer, Edinburgh. Lizars. Edinburgh, 1829. 
This volume, though more than half of it is directed to the conversion 
of the Scottish weights and measures, is calculated to become of the 
greatest use generally throughout Britain. 
The tables are preceded by a “ view of the new system of weights and 
measures,” highly valuable in itself; and the accuracy of the calcula- 
tions is sufficiently vouched for, (at least to ourselves,) by the autho- 
rity of the name of Mr. Buchanan.
