BR J. C. BROWN. 



Revista de Monies, Ano IX., 1st September, No. 207, Madrid. 



The table of contents of this number contains "El Dr. John C. 

 Brown." On turning to this biographical notice, extending to four 

 pages, of our esteemed contributor, by K. Alvarez Sereix, we were 

 reminded that Dr. Brown had recently left Haddington on a visit 

 to a daughter, who is married to a son of the late Pastor Fliedner of 

 Kaiserworth, and who has for many years acted as a missionary 

 in Spain. If British foresters cannot duly estimate the claims of 

 this prophet of education, let them note how this organ of Spanish 

 governmental forestry significantly concludes an article, in which it 

 traces our hero from his birth at Haddington in 1808 till now, 

 with — "Welcome Dr. Brown." In 1833, Dr. Brown w^ent to 

 St. Petersburg as agent for the Bible Society, and returned to 

 Britain in 1840. He again departed to the Cape of Good Hope 

 as a missionary in 1844. Eeturning to Scotland, he became for 

 a time Professor of Botany, not in Edinburgh, as his Spanish 

 biographer makes him to have been, but in Old Aberdeen College.
