Tuese noble works are as honourable to their distinguished 
author and royal patron as they are worthy of the national insti- 
tution from which they proceed, and of they subjects therein repre- 
sented. Well, indeed, may the Museum of Leyden have arrived 
at its present high fame, when those who contributed to its stores 
perceive in how fitting a manner their contributions to the national: 
treasures are made available to the scientific world. The work 
first above mentioned has already been noticed in the 1st volume of 
the Arcana (p. 47,) wherein the first part of the entomological por- 
tion, comprising the genus Papilio, was shortly mentioned. A 
second portion has since been published devoted to the Orthopte- 
rous insects. In the introductory observations upon each family 
its entire generic distribution and structural peculiarities are de- 
tailed, so that the work cannot in this respect be considered as 
confined to the Orthoptera of the East. The text of this livraison 
is occupied with the families Blattide, Mantide, and Phasmide, 
a complete list of the Eastern species known to the author being 
given, together with the descriptions and figures of a great number 
of new ones, some of the latter being of great singularity. The 
plates are beautifully executed, and afford a splendid specimen of 
the capabilities of drawing on stone. Nothing equal to them has 
yet appeared in this country. 
The second work above mentioned is devoted to the Brachyurous 
and Macrourous Crustacea, which are described and illustrated in a 
manner which leaves nothing to be desired, (if we except the want 
of colouring in the plates). The generical and subgenerical details 
are very elaborate, and all the species are represented of the 
natural size, several requiring double folio plates.
