difficulties caused by the preparation of such a large number of plates delayed this com¬ 
pletion beyond the actual close of the past year. This series contains 60 plates, of 
which six are double, and 250 pages of letter press, with explanations of plates, &c., 
and is unquestionably one of the most valuable contributions to the fossil history 
of the Upper Jurassic Cephalopoda ever yet issued. This was all completed, though 
not printed off, wheu Dr. W. Waagen felt compelled to resign his connection with 
the Geological Survey of India. A great source of delay in the completion of the plates 
has arisen from the transfer of our offices to the New Museum, and the time, unavoidably 
lost, in moving and re-setting up the lithographic presses. 
Good progress has also been made in the preparation of plates for the next issue of 
the Pala;ontologia Indica which will be devoted to the fossil flora of Kachh. It was 
hoped that we should have been able to continue the same detailed illustrations of the 
fossil mollusca in the other groups, as have now been published of the Cephalopoda. But 
the loss of our Palseontologist has for the present deprived us of the means of accomplish¬ 
ing this. 
It will be seen that there have been issued during the year no less than 55 plates, 
equivalent, from double ones, to Cl of the regular quarto size, the annual number promised 
being only 48 (originally 24). 
Library .—During the twelve months of 1875, 881 volumes or parts of volumes have 
been added to the Library of the Geological Survey. Of this number, 437 have been received 
from Societies and other Institutions in exchange for the publications of the Survey, or as 
donations, and 444 have been purchased. Quarterly lists of these additions have been 
regularly published as usual in the Becords, and a nominal list of Societies and Institutions 
from which presentations or exchanges have been received is appended. 
The removal of so large and valuable a series of boohs to the new offices of the Survey 
was a task of some risk and trouble, especially during the rains, but it was effected with 
but little injury. The greater space we have now at disposal has already admitted of a 
fuller and more detailed classificatory arrangement of the books than was previously possi¬ 
ble. The completion of this arrangement will, however, necessarily occupy some time, and 
cannot be altogether satisfactorily accomplished until after the completion of the proposed 
gallery and another series of cases. 
The Library continues to be a great resource to students, who can obtain access here 
to books, many of which do not exist in any other collection in Calcutta, or indeed 
in India. 
Museum .—The removal of all the collections from the former offices of the Geological 
Survey to the new Museum was a task of no small trouble and labour, as well as risk. It 
could not have been expected that such a series could be moved without some injury to the 
more delicate fossils, and to the numerous casts of unique animals which our collection 
contains, nor was this danger diminished by the fact that the greater part of the removal 
was effected during the rains. It has consequently taken some time to restore all these things 
to their proper condition. With regard to the rearrangements of the full collections, inasmuch 
as no additional cases have as yet been provided for exhibition, we have been compelled for 
the present to content ourselves with merely grouping the collections and thus rendering 
them more easily accessible for the final arrangement when cases are available. Orders have 
been given for a considerable number already, and it is hoped that some will soon 
be ready.
