sion without interrupting the principal circulation. Thus we see the 
circulation of the wings going on in more or in fewer vessels; thus the 
currents in the antenne and joints of the legs pass to a greater or less 
extent along those organs; and thus a certain degree of desiccation may 
take place in some perfect insects, by means of which the entire flow of 
blood is restricted within the circle in which it probably takes its origin, 
until at length even this vanishes, and death supervenes after a few 
successive oscillations of the heart.’’ 
Of three papers in systematic Entomology contained in the volume, 
the first, by Dr. J. L. T. F. Zincken Sommer, is entitled “ Beitrag zur 
Insekten-Fauna von Java, Erste Abtheilung,’”’ and forms the commence- 
ment of a series of memoirs on the insects of Java, founded partly on 
materials contained in the authour’s own collection, and partly on others 
- submitted to his examination by Dr. Blume, and an unnamed correspon- 
dent. He seems to have been altogether unaware, although the date of 
the publication is in 1831, thata work on the same subject was in pro- 
gress in this country, of which two numbers, containing a portion of 
the Papilionide, made their appearance in 1828 and 1829. Jt is con- 
sequently a somewhat singular coincidence that, in this first section, the 
genera of Papilionide selected for illustration (the arrangement adopted 
being that of Fabricius’s inedited “ Systema Glossatorum’’) almost 
exactly correspond with those which still remain unpublished in Dr. 
Horsfield’s valuable work. In adhering to the Fabrician mode of ar- 
rangement, the authour has had the advantage of possessing a copy of 
the first seven sheets (all that had been printed, when the insolvency of 
the bookseller put a stop to the further progress of the impression) of 
the “Systema Glossatorum,”’ which a lucky chance, as he informs us, 
put it in his power to obtain. It does not appear whether it would be 
possible to obtain other copies of this long-lost treasure, of the existence 
of which we had previously no information; but the manuscript of the 
remaining portion seems to be regarded as irrecoverable. The seven 
sheets which Dr. Zincken possesses, contain descriptions of the species 
of Urania, Amathusia, Papilio, Zelima, Morpho, Cethosia, Castnia, 
Euplea, Apatura, Limenites, and Cynthia, and of the first seven of 
the genus Vanessa, He candidly acknowledges the manifold imper-
