Average monthly relative humidity at 8 a.m. at Masulipatam. 



80-8 



The coldest period of the year is from December to February. 

 This is also the period of least rainfall, but the relative humidity is 

 high in the two last months, there is a heavy condensation of dew at 

 night, and the mornings are damp and foggy. From April to July 

 is the period of highest temperature and lowest relative humidity, 

 and although there is a moderate and increasing rainfall, there is 

 little dew and the mornings are clear and bright. Temperature, 

 rainfall and relative humidity all fall in November, after the reced- 

 ing monsoon, and before the cold weather fogs appear. 



The following tables give figures of deaths amongst the palms 

 observed periodically in a number of villages of Amalapur Taluk 

 in 1907 and the first half of 1908. This period coincides with the 

 origin of a widespread attempt to limit the ravages of the disease. 

 It is probable that, as a result of these operations, the deaths towards 

 the end of the period were less numerous than they would otherwise 

 have been. This does not, however, invalidate the conclusions to 

 be drawn from the figures, as the higher figure in many cases fol- 

 lows the lower.
