bones coloured to indicate their limits and relations, followed 
by a series of the different types of sternum or breast-bone. 
The table-case in the middle of the bay contains illustrations 
of the external characters, the beak, the feathers and the tail, as 
well as of the fore and hind limbs, or wings and feet. By the 
aid of the explanatory labels, the essential characters, and the 
principal modifications of all these parts, can easily be followed 
out by any one wishing to become acquainted with them. 
Bays IV. and V. completing the west side of the hall, will, Contents of 
in a similar manner, show the most important points in the B^^g^^t^ 
structure of reptiles and fishes. In the latter has already been completed, 
placed a very fine skeleton of the Great Blue Shark (Carcharodon 
rondeletii) from Kew Zealand, with the names of all the parts 
affixed to them. 
Of the bays on the east side of the hall, No. YI. is for the 
illustrations of the articulated classes, Crustacea, Arachnida, 
Myriopoda and Insecta, as well as of the Annulosa and Vermes. 
No. VII. for the MoUusca, Echinodermata, Ccelenterata, Porifera 
and Protozoa ; and the remaining three, VIIL, IX., and X., for 
the morphology of the vegetable kingdom: the first containing the 
Cryptogams, the next the Gymnosperms and the Monocotyledons, 
and the last the Dicotyledons. By this arrangement the lowest 
or simplest forms of animal or plant life, those on the border 
land, as .it were, of the two kingdoms, will be brought into 
contact, and at the two ends of the series, in Bays I. and X., 
will be found the groups which show in the highest degree 
the special attributes of the division to which they belong. 
The Introductory Collection of Minerals will be found in the 
gallery devoted to that department of the collection (see p. 46).
