them pieces of tissue or blotting-paper, cotton-wool frequently 

 giving them a spotted appearance. The natural colour of the 

 flowers begins to reappear soon after the acid has been removed, 

 and returns completely in the course of a day or so. It is better 

 to expose them for a few minutes to the air before pressing. 

 The effect of the acid, besides temporarily bleaching the flowers, 

 is to prevent the growth of fungus, which otherwise destroys the 

 colour. The tint, when it returns, is at least comparatively per- 

 manent. I have by me specimens of Sweetbrier dried several 

 years ago that are still quite bright. Even with the greatest care 

 there must be inevitably many failures. So the collector must 

 preserve a large number of specimens and select the best.

The Baron von Mueller Grave Memorial. — The monu- 

 ment erected over the grave, in the St. Kilda Cemetery, of the 

 late Baron Sir F. von Mueller, K.C.M.G., for nearly 45 years 

 Government Botanist of Victoria, was unveiled on Tuesday after- 

 noon, 26th November, 1901, by His Excellency the Governor- 

 General, Lord Hopetoun, in the presence of a large gathering of 

 public and scientific men and personal friends. Among those 

 present were Professor Kernot and Dr. Jamieson, representing 

 the Royal Society ; Mr. J. G. Luehmann, F.L.S., Government 

 Botanist ; Mr. W. R. Guilfoyle, F.L.S., Director of the Melbourne 

 Botanical Gardens ; Mr. J. H. Maiden, F.L.S., Director of the 

 Sydney Botanic Gardens ; Mr. M. Holtz, Director of the Ade- 

 laide Botanical Gardens ; Mr. C. French, F.L.S., Government 

 Entomologist ; and Mr. D. M'Alpine, Government Vegetable 

 Pathologist, &c. The Field Naturalists' Club was repre- 

 sented by the president, Mr. T. S. Hall, M.A., the 

 editor of the Victorian Naturalist, and several other 

 members. Speeches were made by several public men, but 

 that by Professor Kernot may be quoted as embodying the 

 feelings of most of those present. He said the deceased was a 

 typical man of science, devoted to the pursuit of truth, without 

 any thought of his own immediate gain. He studied the laws 

 of Nature, which were the thoughts of God. It seemed as though 

 there were no part of botanical science he had not touched. 

 An earnest and hearty response had been made from all parts 

 of the world to the appeal for funds for the erection of the monu- 

 ment to him who was one of the kindliest, most generous, and 

 most simple-minded of men. Mr. J. H. Maiden said that only 

 future generations would realize the greatness and value of Baron 

 von Mueller's work. The monument is in the form of a tall 

 column of polished stone, surmounted by an urn, and resting on 

 a broad pedestal. A medallion in copper of the profile of the 

 late Baron is let into the stone above the inscription.
