construction and present a handsome appearance. Those for the 

 geological, entomological, and nest collections are from special de- 

 signs. This new hall is devoted exclusively to the Natural History 

 of Perthshire and the Basin of the Tay, the different sections being 

 worked out with more or less completeness, according as the different 

 members of the Society have been able to accomplish their self- 

 allotted tasks. Thus the birds, the nests, the mammalia, the mol- 

 lusca, and the mosses are all nearly complete, so far as the known 

 Perthshire species are concerned. In the phanerogams space will 

 only admit of each genus being represented, and the same applies 

 to the vascular cryptogams. In the insecta, only a beginning has 

 been made, but there is a very large amount of material in the 

 Society's possession waiting to be arranged. The geology is well 

 advanced, the collections in this department being arranged not 

 altogether on stereotyped lines, but with a view to illustrate the 

 dynamical and structural as well as the stratigraphical geology of the 

 district. A good beginning has been made in the fishes, amphibians, 

 and reptiles, and also in a collection of the indigenous trees of 

 Perthshire. 



All the Perthshire specimens have been removed from the old 

 Museum Hall, which it is intended to devote to an Index or Type 

 Collection, arranged according to the most recent biological prin- 

 ciples. In connection with the Museum there is a well-equipped 

 Laboratory and a Herbarium Room, as well as a Scientific Library 

 and a Lecture Room. The Society has generously thrown the 

 Museum open to the public entirely free of charge. 



ZOOLOGICAL NOTES. 



Daubenton's Bat in Glen Doehart, Perthshire. In a previous 

 note upon Daubenton's Bat (Vespertilio danbentoni) ("Annals of 

 Scottish Natural History," 1894, pp. 193-195), I wrote regarding my 

 observations at Loch Doehart during July 1894. This year I was 

 living some distance from the loch, and had no opportunities of 

 watching the bats at night. I however twice visited the rocks in 

 the crevices of which the bats live, and on my first visit on the 6th 

 of July found them in possession, as when observed the previous 

 year. On this occasion there was considerable excitement in the 

 colony, though I did not unnecessarily disturb them, but less commo- 

 tion than in July 1894, when I visited their haunts later in the 

 month and when the breeding season was more advanced. The 

 rock at the entrances to the crevices was coated with a black, greasy- 

 looking substance that either comes from the bodies of the bats, or 

 is their excrement rubbed on to the rock from their feet as they
