of these acquisitions may be mentioned the collection of Count 
Munster's Duplicate Fossils, the Image Collection of Chalk Fossils, 
Fletcher's " Silurian Collection" and the Leckenby Collection of Oolite 
Fossils chiefly from Yorkshire. The last-mentioned magnificent 
series was purchased with funds subscribed in response to an appeal 
made by Professor Sedgwick, in which he speaks in a most touching 
manner of his being prevented by the infirmities of age from enriching 
the collections by his personal efforts. For many years the great 
accumulation of specimens had no fitting place for their reception, 
the only apartment assigned to him for this purpose being a room in 
which the specimens were stored, generally in packages in which 
they had come to Cambridge. Such a state of things was most 
unsatisfactory, and Professor Sedgwick exerted all his influence to 
put an end to it. In 1842 he obtained possession of the fine suite 
of rooms under the new building of the LFniversity Library, in which the 
collections are at present displayed, and he devoted himself with his 
accustomed enthusiasm to the task of arranging the specimens in a 
manner best adapted to advance the study of geology in the University. 
He secured the assistance of a succession of able coadjutors in the 
persons of Ansted, Jukes, Salter, M'Coy, Barrett, and Seeley, under 
whose hands the treasures of the museum were gTadually brought 
into order, and in many cases described. The Palaeozoic Fossils gave 
origin to the descriptive catalogue of Professor M'Coy, published in 
1851-5, and to the contributions to British Palaeontolog}^ of the same 
author ; whilst at a later period Professor Seeley published catalogues 
of the reptilia of the secondary strata, and Ornithosauria from the 
Cambridge Greensand founded on the specimens contained in the 
museum. In an index supplement prepared by Mr. Salter, Professor 
Sedgwick wrote an elaborate preface, in which he explained his 
views as to the nomenclature and classification of the palaeozoic 
rocks, and which may serve as a summing up of his side of the 
question at issue between Cambria and Siluria. In this preface 
Professor Sedgwick expressed himself as follows : — " There were three 
important hopes which possessed my heart in the earliest years of my 
Professorship, 1st, that I might be enabled to bring together a 
collection worthy of the University, and illustrative of all the depart-
