Prof. Oberbergrath Dr. Waagen, formerly Palaeontologist of the Survey, 

 but now in the Polytechnic University of Prague, still retaining his 

 hold on the study of Indian Geology, has within the last year pub- 

 lished an exhaustive paper in the Jahrbuch der K. K. Qeol. Beicli- 

 sanstalt, Vienna, on the Carboniferous Glacial Period, which owes 

 much of its value to observations and deductions made from time to 

 time, since 1856, by the Geological Survey in working out the Gond- 

 wana Formation, particularly in connection with correlated deposits in 

 South Africa and in Australia, glacial evidences of more or less import- 

 ance having at the same time been observed in all. This correlation, and 

 homotaxy, according to Dr. Waagen's latest deductions, is shown in the 

 annexed statement.
