66 NATURAL SCIENCE. Jan., 1895. 



Botanic Society of Edinburgh. For some time he was Examiner in 

 Natural History at Aberdeen University. 



Dr. White had the valuable faculty of gathering around him in 

 Perthshire a band of disciples, full of enthusiasm for natural history 

 pursuits; but in late years, with somewhat impaired physical strength, 

 he mainly contented himself with guiding their studies in the 

 several departments for which they showed a special aptitude and 

 liking. Many students of natural science, beyond the city and county 

 of Perth, owe much to his kindly sympathy and ready help. He was 

 the prince of field-botanists, and his friends in the north will long 

 cherish happy memories of scrambles among the crags and corries of 

 the Perthshire hills in the company of Buchanan White, ever the 

 cheery comrade, fleet-footed leader, keen-eyed observer, and patient 

 teacher. 



FRIEDRICH BIDDER. 

 Born 1810. Died August 27, 1894. 



BIDDER was born at Landohm, in Kurland. He became Professor 

 of Anatomy at Dorpat in 1842, and from 1843 to 1869 Professor 

 of Physiology at the same place. There also he died. His work lay 

 chiefly in human physiology, but he paid some attention to the 

 Amphibia — " Bidder's organ " in this group taking its name from 

 him.

E learn from the Geological Magazine that Richard Meade, of the 

 Mining Record office, was born in 1827 at Dublin. His chief

 but he is probably best known as the author of " The Coal and Iron 

 Industries of the United Kingdom," which was published in 1882.
