Not many of our annual books of reference condescend to pay much atten- 

 tion to scientific affairs, and we must therefore specially commend " Hazell's 

 Annual " for its excellent abstracts on the Australian Meeting of the British 

 Association last year, on Anthropology, Astronomy, Geography, Geology, and 

 Medicine and Surgery. The "Annual " also even gives information regarding 

 the Nobel Prizes — while another one we know mentions only the Peace Prize, 

 and does not even refer to the scientific prizes, which some will think infinitely 

 more important.
