lviii PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [May I903, 



to the public in his ' Geological Sketch of the Province of Cadiz,' 

 published in 1872, a memoir which at once attracted the attention 

 of scientific men on account of its breadth of treatment. 



In 1874 Macpherson took up his residence at Madrid, where he 

 built later on his little mansion in the Calle de la Exposicion, which 

 under his fostering care became a sort of geological institute, for 

 the use of himself and his friends. Here he lived for many years, 

 making, however, annually excursions into foreign lands. He became 

 a member of nearly all the Geological Societies of Europe (being 

 elected a Eellow of our own Society in 1890), and belonged to some 

 of those of Geography and Natural History ; but he never occupied 

 any official post, or accepted any titles or honours of any kind, 

 except that of President of the Spanish Society of Natural History, 

 and that of Corresponding Member to the Institute of France. 



Of stratigraphical papers of the ordinary type Macpherson wrote 

 few. The most important was one ' On the Geology & Petrography 

 of the Province of Cadiz,' published in 1878, and another on the 

 ' Stratigraphical Succession of the Archaean Hocks of Spain,' published 

 in 1884. 



On the orogenic side of geology Macpherson was an enthusiast, 

 following along the same general lines as Dana, Suess, and their 

 colleagues and sympathizers. His first paper on the subject was 

 published in 1878, ' On the Dynamic Phenomena which deter- 

 mine the Special Structure of the Serrania de Honda ' ; and this was 

 followed in 1879 by his brief note concerning ' The Special Struc- 

 ture of the Iberian Peninsula.' Not only was he a pioneer in orogenic 

 work in Spain, but we owe to him a large part, if not almost the 

 whole, of what is known and has been quoted up to the present 

 time concerning the structure of the Peninsula. In 1880 he pub- 

 lished his paper ' On the Predominance of Uniclinal Structure in 

 the Iberian Peninsula'; in 1886 his memoir on 'The "Relation 

 between the Forms of the Coasts of the Iberian Peninsula, 

 the Principal Lines of Fracture, and the Sea-Bottom ' ; and the 

 conclusions embodied in these he extended in two succeeding papers 

 published in 1888. In his very last memoir — an essay ' On the 

 Evolution of the Iberian Peninsula,' which appeared in 1891— he 

 summarized the results of his own personal investigations, made 

 in many a toilsome journey across his native land, and synthetized 

 his broad and original views as to its geological structure and 

 history. 



Macpherson was hardly less interested in dynamic geology, although 

 he published very few papers dealing with that branch of the science ;
