habits and thoughts were influenced as well by its bright, cheerful, 
and inspiriting aspects as by the darkness and dangers of storms 
and the hardships of a sailor’s work. With trusty companions he 
weathered the tempests ; and his natural gaiety, real good-nature, 
and high moral principles enabled him to be cheerful and straight 
amidst rough but well-intentioned comrades. So in after-life, 
through years of hard work and narrow means, hopefully and per- 
sistently he improved his knowledge as schoolmaster, and before 
long as tutor and lecturer in mathematics and the natural sciences. 
About 1840 geology attracted his attention, and ever afterwards he 
assiduously worked at the rocks and fossils of Cornwall and Devon 
in sympathy and correspondence with many geologists of note. The 
geological structure of the country, the fossil fishes of Polperro and 
elsewhere, the clay-beds and lignites of Bovey Tracey, and espe- 
cially the varied contents of the Bone-Caves of Happaway Hill, 
Brixham, and Kent’s Hole, excited his scientific energies, using up 
his leisure and his holidays. The results of his work, complete in 
itself and trustworthy in its exactitude, gave him a high standing 
among the intellects of the day. His knowledge was widely sought 
for and freely imparted. The extensive correspondence with the 
Author of the ‘ Principles’ and ‘ Elements of Geology’ alone shows 
what influence Pengelly’s experience and philosophic acumen had 
on the establishment and progress of geological science. 
Of Pengelly’s geological work and of his various published papers 
(119 catalogued at pages 323-329), Dr. Bonney’s Appendix 
(pages 291-322) is a complete, critical, and scientifically correct 
account, written with a deep and affectionate sympathy for the 
deceased friend and fellow-worker. 
Mr. F.8. Ellis, an old friend and neighbour at Torquay, has 
written the Preface for the Memoir, with a full knowledge of his 
deceased friend’s life and circumstances. He truly observes :—“ It 
can scarcely fail to force itself on the reader of the ensuing pages 
that the special note of William Pengelly’s character, apart from the 
energy, perseverance, clear-sightedness, wit, and abundant good 
humour which distinguished him, was his extraordinary unselfish- 
ness.” 
In many directions during his life Pengelly was in touch with 
different classes of society, and left incidental notes of their ways 
and thoughts. These collected records (1812-1894) constitute a 
not unimportant part of the history of British science, and, indeed, 
a good chapter of English history, as to the people of various degrees 
and conditions, in their intellectual aspect. 
His influence for good affected a large circle, both of those who 
knew him and those who have known his writings. It wasa steady 
light replacing the gloom around it. For the advancement of good 
and useful knowledge he laboured hard for many years, as the 
several Institutions and Museums of Devon, Cornwall, and elsewhere 
can testify, and as the elaborate “‘ Memoir” before us fully shows, 
Not only of ‘* Men of Might,” battling against armed enemies, but
