4. Annual Report of the Board of Scientific Advice for 

 India for the year 1912-18. Pp. 190*. Calcutta, 1914.— This 

 volume, like its predecessors, gives a digest in very concise form 

 of the scientific work accomplished for the Indian Government by 

 members of the Board — some twelve in number — with their asso- 

 ciates. The entire range of science, both general and economic, 

 is included, so that the information here briefly summarized is of 

 very varied character and of much interest. The chapter on 

 Geodesy, by the superintendent of the Trigonometrical Survey, 

 Lieut.-Col. G. P. Lenox-Conyngham, is particularly interesting, 

 and some of the conclusions from the measurements of gravity by 

 pendulum observations during the year are quoted here. These 

 determinations were made at fourteen stations along a line extend- 

 ing from Bhopal to Khurja, near Bulandshahr, including Kalian- 

 })ur, the station of origin of the Indian triangulation. This 

 completes a chain of stations along the meridian of 78° from Mus- 

 soorie (Lat 30° 28') to Amraotl (Lat. 20° 56'), a distance of 

 about 650 miles. The results stated briefly are as follows : 



"From Mussoorie to Gesupur (Lat. 28° 33') the defects of 

 gravity decrease rapidly from '11 to -02 dynes. Between Gesupur 

 and Khurja we find a rise to "04 and from thence to Agra the 

 negative residuals again decrease, becoming positive at the latter 

 station. Between Agra and Bina we find two belts of deficient 

 gravity or "valleys" separated by a positive area or "ridge." 

 From Bina to Amraoti we have a succession of positive values 

 with only two small negatives at Bhopal (-004) and Shahpur, lati- 

 tude 22° 12' (-005.) 



" The existence of this area of excessive gravity, often called 

 the hidden chain, was deduced by Colonel Burrard in 1901 from
