A comparison of tlie second, third and. the sixth lines of the table 

 shows a remarkable relationship between a high ground water-level and 

 high spleen-rates and fever mortality of the thanas and vice versa. 

 Thus at Porsa the ground water-level was 33 feet down, and the spleen- 

 rate was only 28*3, the lowest met with, while the fever death-rate of 

 29 05 per thousand was also the lowest of all the thanas. Exactly the 

 reverse holds good of the Ranisankil circle, in which the highest ground 

 water-level coincides with the highest spleen and fever-rates. Similarly, 

 Dinajpur, Birganj, and Thakargaon thanas show high ground water- 

 levels and spleen and fever rates, while those of Balughat and Chura- 

 man have lower rates approaching those of Parsa. The Dinajpur 

 spleen-rate was not as high as might have been expected, but the num- 

 ber of children examined in that circle was small. Turning next to 

 line 9, which shows the fever death-rate per thousand in the circles 

 examined, we find a remarkably close relationship between the death- 

 rates of these small circles and those of the thanas in which they are 

 situated (line 6), clearly showing that the number of deaths enquired into 

 in each circle were sufficient for the purpose of getting fairly accurate
