which he presented in after years to the Botanical Museum at 
Kew. 
In 1835 Mr Trevelyan married Paulina, the oldest daughter of 
the late Rev. Dr Jermyn, who lived until the year 1866. 
After the British Association for the Advancement of Science had 
been founded in 1831, Mr Trevelyan took a deep interest in its pro- 
gress. He served on the local committee of the Association when 
it met in Newcastle in the year 1838, and he was afterwards a 
member of the Council of that learned body. At the thirty-second 
meeting of the Association in the year 1862, he was elected one of the 
Vice-Presidents, his colleagues being Sir C. Lyell, Hugh Taylor, 
Isaac Lowthian Bell (Mayor of Newcastle), Nicholas Wood, the 
Rev. Temple Chevalier, and Mr (afterwards Sir William) Fairbairn. 
Sir Walter came into possession of his estates and title in the 
year 1846, and from that time resided principally at his beautiful 
estate at Wallington, near to Cambo, Northumberland, a mansion of 
great historic note, and once the seat of a famous Jacobite, whose 
opinions cost him his life — Sir John Fenwick. He was elected 
Deputy-Lieutenant of the County in 1847, and in 1850 served the 
office of High Sheriff. 
His time was much devoted to the improvement of agriculture 
and to the social amelioration of the condition of the people. He 
also took a deep interest in public affairs, and as far back as 1853 
he became the first President of the United Kingdom Alliance for 
the suppression of the sale of intoxicating liquors, which office he 
continued to hold until his death. 
In addition to his tastes for science, Sir Walter Trevelyan was a 
willing patron of the fine arts, and collected at Wallington some 
exquisite artistic works, in addition to a perfect museum of natural 
history. He was a Fellow of the Society of Antiquaries and a 
zealous antiquarian, and has left to the British Museum and the 
Society of Antiquaries valuable legacies. He was a clear and concise 
writer, and contributed several very useful papers on geological and 
botanical subjects. He was also a thoughtful and collected public 
speaker, who made every sentence he spoke tell, and who never 
wasted a sentence or, it may almost be said, a word. 
In 1867 Sir Walter married, for the second time, Laura Capel, 
the daughter of Capel Lofft, Esq., of Troston Hall, Suffolk, who
