away, after cataloguing, in boxes, a very large part of the series, and simply store them in the 
godowns ; this difficulty which involves a very large share of additional work, whenever refer¬ 
ence to, or comparison of, these specimens becomes necessary, will be unavoidable until the 
Museum obtains proper space for the exhibition of its collections and for rendering them 
accessible to those who desire to study them. 
Mr. Tween, Curator, has been steadily progressing with the detailed examination of the 
coals of India in connection with the detailed experiments as to their actual ‘ duty, which are 
being carried out by Colonel H. Hyde, b. e., at the Mint Offices. When completed, it is hoped 
that these combined assays and actual trials will g’ive a very much more trustworthy and 
accurate test of the relative values of the various coals of India, than lias hitherto been 
obtainable. The specific gravity of each coal is carefully determined, and the general assay or 
composition; and then careful analysis of the ashes of the coal is made, showing the 
nature of their composition and the presence or absence of ingredients, which, though in small 
quantities, would exercise possibly a very seriously injurious elfect on the results ol the em¬ 
ployment of these coals in manufactures, such as smelting of irou, &c. 
Meteorites. —As stated in the Records of the Survey, 1870, pt. 4, p. 104, we have 
added to our large collection of Meteorites, during the past year, specimens of the fall at 
Hessle, near Upsala, on the 1st of January 1809; of that of Kernouve or Clegueree, Morbi- 
lian, Prance, of the 23rd of May 1869; also a fine specimen of the iron of Deesa, Chili. 
As customary, an index map on a small scale is appended, showing roughly the present 
state of the survey; as also a list of those Societies or public Institutions from which we 
have received publications during the twelve months in exchange for those of the Geological 
Survey of India. 
The various collections are all in as good order and safe keeping as the nature of the 
accommodation at our command will permit.
