256 REPORT OF MEETINGS FOR 1905 



Mr Patrick Dudgeon of Cargen, Professor Heddle of St. 

 Andrews, and Dr Wilson of Wanlockhead; but not till 1894 

 did the collection attain its present unique character through 

 the presentation to the Museum of Dr Heddle's unrivalled 

 collection, numbering upwards of eight thousand specimens. 

 Since then the Scottish Minerals already in the Museum have 

 been incorporated with these specimens into one collection, 

 and classified and arranged by Mr Goodchild, partly under Dr 

 Heddle's personal supervision. The Minerals are arranged in 

 duplex series, those in the upright cases, which are lettered 

 in white, being show-specimens for the instruction of the 

 general public, and those in the flat cases, which are numbered 

 in red figures, being arranged to meet the requirements 

 of mineralogists and crystallographers. The plan of classi- 

 fication adopted in both is that employed in the last edition 

 of Dana's "System of Mineralogy." While indebted for the 

 above minute details of the arrangement of this department 

 to Mr Goodchild's own description supplied in two pamphlets 

 published by the authority of the Director of the Museum, 

 we recall his own interesting and enthusiastic explanation of 

 the same to the members of the Club, and his lucid reference 

 also to small models to scale of the Sun, the Inner Planets, 

 the Earth, and the Moon, which were ranged around the 

 open space in the centre of the Gallery. The original 

 intention in placing them there, he explained, was to 

 convey to visitors, as in the similar exhibit at the Museum 

 of Practical Geology in London, some idea regarding the 

 vastness of the distances with which astronomy has to deal, 

 and, in conveying this impression, to enable the mind to 

 grasp the conception of the duration of Geological Time. 

 Before leaving the building the members accorded the 

 Curator a hearty expression of thanks for his painstaking 

 explanation of the Collections brought under their notice. 

 Proceeding along the South Back of the Canongate in the 

 direction of Holyrood, the members had their 

 Arthur's attention drawn to the general features of 



Seat. Arthur's Seat and its surrounding area by Mr 



Goodchild, who illustrated his description by 

 means of a coloured model. His untimely death, however, 

 so much deplored by many of our number, has deprived
