138 The Scottish Naturalist. 



PROCEEDINGS OF THE PERTHSHIRE SOCIETY OF NATURAL SCIENCE. 



Vol. II., pt. Ill, 1882-83, is, as usual, a record of good work, not only in the 

 way of papers read during the session, but also in the practical side of excur- 

 sions made with the view of extending the knowledge of the fauna and flora 

 of Perthshire, and still more in adding to the Museum of the Society, and in 

 making the collections full and reliable indications of the riches of the county. 

 The residents of Perth will, beyond doubt, feel pride in the existence of so 

 well-organised an institution in their fair city, while strangers passing through 

 Perth will now be able, even though with little time at their disposal, to gain 

 -a fair knowledge of the leading features of its fauna and flora. That the 

 Society may have great success and satisfaction in the good work that they 

 have undertaken must be the wish of every lover of botany and of zoology. 



Besides the reports of the officials of the Society, and of the meetings held 

 during the previous session, the following papers are printed in extenso : — 

 "The Present Condition of the Museum," by Dr. F. Buchanan White; 

 "Light," by Dr. T. Miller; an obituary notice of Mr. John Sadler, late 

 Curator of the Edinburgh Botanic Gardens, by the Secretary ; " Autumn 

 Tints : their Why and Wherefore," by H. Coates ; " The Cultivation of Fruit 

 on Waste Lands and Pleasure Grounds," by Dr. Robertson ; " Mimicry in 

 Insects," by S. T. Ellison. 



Four excursions were made during the summer to the following places, viz. : 

 1. Banks of the Tay below Errol ; 2. Methven ; 3. Loch Ordie ; 4. Kincardine 

 Glen. These excursions were, as usual, productive alike of pleasure to those 

 who took part in them, and of information as to the natural productions of 

 the districts visited. Space will hardly allow us to enter into any analysis of 

 the results here, however.
