PROCEEDINGS—PERTHSHIRE SOCIETY OF NATURAL SCIENCE. lv 
I pass on now to an account of the Museum work which has 
occupied my time since last year. 
Perthshire Museum — I described last year a form of glass-topped 
insect store box, with grooved sides, which is interchangeable along 
the whole of the north wall cases of the gallery, to contain our local 
Insect Collections. To this series 45 trays or boxes have been 
added, to accommodate the Hemiptera and part of the Lepidoptera. 
Continuing along the east wall, I have had made a series of trays, 
the bottoms of which project half-an-inch along each side, and fit 
into corresponding grooves in the sides of the presses. This series 
of trays is interchangeable along the east wall, and will accommodate 
ultimately our additional and duplicate Rock, Mineral, and Palseonto- 
logical local collections. Temporarily I have arranged zoological 
reference and duplicate specimens in them. These were previously 
packed away or stored in various cupboards, with no attempt at 
systematic arrangement. 
Index Museum. —The group “Worms,” including the Polyzoa and 
Brachiopoda, is being arranged in the wall cases 5 and 6, and is 
slowly nearing completion. I may mention I have for the first time 
employed the hand-press for the printing of small descriptive labels 
for this group. The classification used is that given in the Cambridge 
Natural History. 
The Fishes, which are to have 4 cases to illustrate their affinities 
and general anatomy, have received a considerable amount of 
attention. They are being arranged in the north upright case, facing 
the Birds. The first case, dealing with the simplest forms of verte¬ 
brate animals, leading up to the Elasmobranchii , or Cartilaginous 
Fishes, is finished, so that, having other 3 cases yet to do, I reserve 
my remarks till a later date. 
At the end of the Invertebrate cases (13) a series of specimens 
have been mounted and grouped showing various interesting points 
in the study of Birds, such as broad and narrow wings in birds of 
flight; the wing of a Penguin, as an example of a flightless bird; 
section of a wing, to show hollow bones; a skeleton; the various 
forms of feet as in running, scraping, perching, grasping, wading, 
swimming, etc.; the various colours, sizes, and shapes of eggs; the 
different forms of nests; a series of heads, to show variety in form of 
beak; and three types of skulls, with the corresponding bones of the 
palate in each coloured with the same tint to emphasise their shape 
and position—an important character in the classification of birds. 
The Mammal cases have been re-arranged, and printed labels 
descriptive of each order introduced. The glass shelving is retained 
in this series in the meantime. 
The Double Table Case (C. D.), containing the Rock specimens, 
is now completed. For a description of the arrangement and purpose 
of this collection I may refer to the Opening Address of the President, 
delivered at the beginning of the present session. 
Lastly, our collections of Exotic, Land, and Fresh Water Shells 
have been identified and named. I am therefore in a position to go 
on with the arrangement of Table Case H.
