Lecturer of St. John’s College, Cambridge, and University 
Lecturer in Geology. 
(WITH A PORTRAIT, PLATE XI.) 
fJ\HE subject of the present memoir occupies a distinguished 
position as lecturer and teacher of our science in the 
University of Cambridge, one which he has held for more than 
thirty years, and he is well known among geologists generally as 
a high authority on the Paleozoic rocks, his writings being recorded 
in the “Quarterly Journal’”’ of the Geological Society (of which 
Society he has filled the offices both of Secretary and President). 
His name has also frequently appeared as the author of important 
papers in the Gronoeicat Macazrnx and other works. 
John Edward Marr, the third son of John and Mary Marr, was 
born at Morecambe, Lancashire, June 14, 1857; he was educated at 
the Lancaster Grammar School, already famous as having been the 
nursery of two eminent scientific men, Dr. Wm. Whewell, F.R.S., 
Master of Trinity, and Professor Sir Richard Owen, K.C.B., F.R. g.. 
Hunterian Professor at the Royal College of Surgeons and afterwards 
head of the Natural History Departments i in the British Museum. 
For some years before entering Cambridge, Marr lived at Carnarvon, 
where his interest in geology was aroused among the rocks of 
Snowdonia, and when at school he had the advantage of geological 
teaching from the Rev. Thomas Adams, M.A., and practical work in 
the field under Mr. R. H. Tiddeman, M.A., F.G.S., who was then 
surveying the Lancaster district. 
In 1875 J. EK. Marr entered St. John’s College, Cambridge, with 
an Exhibition, and had the benefit of studying under Professor 
McKenny Hughes and the Rev. T. G. Bonney, in the lecture-room, 
museum, and field. By his application Marr obtained a Foundation 
Scholarship, and graduated First Class in the Natural Science Tripos 
in 1878. 
The year following he spent some weeks in a careful study of the 
Lower Paleozoic rocks of Bohemia and critically examined Barrande’s 
so-called ‘colonies’, of which that accomplished geologist had 
published so much. The writer recalls the humorous remark of 
Professor Huxley at a Council meeting of the Geological Society, 
that now Marr had upset Barrande’s interpretation of these isolated
