which it actually traversed, and the course of the cyclone across 

 Bengal took place where the air-motion was relatively least, prior to 

 its advent. 



The arrival of Mr. W. L. Dallas, appointed Scientific Assistant 

 to the Meteorological Reporter to the Government of Tndia, enabled 

 the important work of reducing and discussing for publication the 

 marine meteorological observations collected during the 20 years 

 1856-75 by the London Meteorological Office to be taken up, and 

 a beginning was made with the barometic and wind data of the Bay 

 of Bengal for the month of January. 



"With regard to the collection of current meteorological data for 

 the Bay of Bengal this was undertaken by Mr. Eliot. Observations 

 were regularly recorded with duly verified instruments on board the 

 light-ships off the mouth of the Hugli, and a form of return 

 showing the meteorological information which it is desired to 

 obtain was handed to the captain of every vessel. A large number of 

 captains duly responded to this appeal, and information of great 

 value was derived from their returns On the whole the extracts 

 proved that the weather in the whole extent of the bay (excluding 

 the Andaman sea) was fairly indicated by the observations taken at 

 the coast stations, and that the progress of every important storm 

 might be traced and followed with more or less exactness, almost 

 from its origin, from the shore observations. 



Among the more important incidents of the year 1883-84 should 

 be mentioned the arrival of Sergeant Rowland and Mr. Shaw at 

 Leh, in November 1883, for the purpose of instituting actinometric 

 observations there. For some months previously they bad been 

 undergoing most valuable training at the hands of Mr. Hennessey 

 at Dehra. 



A body of valuable information with regard to the question of 

 the influence of the Himalayan snowfall on the dry westerly winds 

 in Northern India was obtained from officers stationed in the Hill 

 States, and the abnormal features of the snowfall in the spring and 

 winter months enabled Mr. Blanford to frame forecasts with regard 

 to the duration and nature of the dry winds in the plains, which 

 were fairly justified by the events. During the year observatorir? 

 were established at Kailang, in Lahul, at an elevation of 10,000 feet 

 above the sea, and to the north of the second survey range, and also 

 at Chamba. 



Among the more notable publications of the year were Part II. of 

 Vol. II. of the Indian Meteorological Memoirs, containing a memoir
