Hindu Achievements in Exact Science. A Study in the History of Scientific 

 Development; by Benoy Kumar Sarkar, Professor, National Council of 

 Education, Bengal. Longmans Green & Co. 82 pp. $1.00. 



It is seldom that a book of such slender proportions contains such an ency- 

 clopedic amount of information, written, withal, so interestingly. As the 

 advertisement states, "The main object of this little book is to furnish some of 

 the chronological links and logical affinities between the scientific investigations 

 of the Hindus and those of the Greeks, Chinese, and Saracens." The claims of 

 the brilliant young author, for Professor Sarkar is a young man, are supported 

 by a bibliography of seventy-two names of which fifty-one are non-Hindu, 

 most of them English. 



He reminds us that positive science is btit three-hundred years old, even in 

 Europe, and that the Saracens are admitted to have been the teachers of the 

 Greeks in those distant times which are here characterized as the prescientific 

 era of science. The Saracens having learned from the Hindus, the latter were 

 at least on a par with the European nations until the 13th century A.D. We 

 must remember that "we are now living in the midst of the discoveries and 

 inventions of the last few years of the nineteenth century."
