    remained at the head of the Department from its commence- ment in 1851 to 1876, he would, unquestionably, have been admirably qualified to carry out the work; and it was his own desire to do so, as the completion of his labours in India, hailing health, however, and the pressure of other duties, prevented him from even commencing the task; and when, at length, he was unable any longer to remain in the country; the duty of preparing a Summary of Indian Geo- logy was left to his successor. At this time, the only pre- paration that had been made for the work was the partial compilation of a general Geological Map of the Peninsula. The double authorship was not entirely a matter of choice; although undertaken, and carried out, most willingly by both the writers. Both have been engaged in the wrork of the Survey almost from the commencement; and as each has, in the course of his service, examined very large areas of the country, the combination secures the description and discussion, from personal knowledge, of a much larger por- tion of India. At the same time, the advantages of wider experience and thought may not be found an adequate compensation for want of uniformity and occasional dis- crepancies—the natural results of divided authorship. To secure, so far as possible, the responsibility of each author for the facts and opinions stated, the initials of each are affixed in the Table of Contents to the chapters contributed by him. Every such chapter has been read and revised by the other writer; but the alterations have in no case been of more than trivial importance; so that each chapter may be practically taken as an individual contribution. The number of subjects is so large, and the connexion between them, in many cases, so slight, that the lack of uniformity will not, it is hoped, seriously detract from the usefulness of the Manual. In addition to the subjects discussed in the present work, it was, at first, proposed to add an account of the Economical Geology, and to treat in a special chapter of the known Mineral Itcsources of India. But the length to which the • Manual has already extended, has rendered it advisable to
