during this operation our good friend the Janitor cleaned about 2000 
square feet of plate glass. 
The only addition of importance to this collection is a male Wax¬ 
wing in adult plumage. 
The Fish Case is undergoing a complete change. The glass 
cylinders are to be abandoned, and square tanks constructed of plate 
glass are to take their place. About ten of these, varying in size from 
12 in. by 6 in. to 3 ft. by 9 in., are already constructed. These permit 
the placing of the fish in their correct position, instead of standing on 
their tails, and the exhibiting of them amid their natural surroundings. 
In the case of the Salmon and Trout the life history is also shown. 
The Invertebrate Collection has received an important addition, 
namely, the collections of Perthshire Lepidoptera formed by the late 
Sir Thomas Moncreiffe, which have been handed over to the care of 
the Society by Sir Robert Moncreiffe, Bart. 
The subject of the recent Children’s Essay Competition, “ The 
Trees of Perthshire,” included not only the native trees, but the choice 
of a number of introduced forms. It was thought advisable, there¬ 
fore, to extend the tree section to include six of the more important 
of these. In the meantime this extension into the Invertebrate wall 
case will remain until the section is required for the completion of 
the Perthshire Invertebrate Animals. 
Mr. R. H. Meidrum sends the following note on the Moss 
Collection:—“ During the winter the Perthshire Mosses from the 
late Dr. White’s Herbarium have been examined and mounted in a 
suitable manner. At the same time, specimens collected by Mr. 
MTntosh of Inver and the late Mr. Martin of Aberuthven have been 
incorporated, and I have added a large number from my own 
Herbarium. Only a few critical species now remain unmounted. 
I hope that ultimately each species may be represented from every 
district in which it occurs, and that those Members who have 
recently shown an interest in Bryology will contribute to this end by 
collecting specimens for mounting. The commonest species are 
most required from many of the districts.” 
The Fungi have received considerable attention this year, and 
over 60 species of the Agaricini have been collected by Miss Miles 
and Mr. Jas. Menzies. These examples were all photographed by 
Miss Jamieson or myself, and afterwards preserved in spirit. A part 
of the Herbarium has been fitted with shelves, and in these they are 
arranged. 
Index Museum . —Three more cases have been fitted up in this 
department on the tablet system. First, the Protozoa. As all the 
animals comprised in this group are small, indeed, mostly micro¬ 
scopic, models and drawings are largely used. In the second case 
the Sponges are shown to splendid advantage on the black tablets, 
particularly the siliceous forms, of which the Museum now possesses 
a fine collection. The commercial sponges also are well represented. 
In both cases white sketches on black tablets illustrate the structure 
of the groups. 
The third finished case contains the class Amphibia. In this the 
central tablets show the anatomical features, and on the left are
