210 Report on the Progress of the Magnetic Survey. [No. 3. 



I beg to bring to the notice of Government the many and important 

 services which Mr. Monteiro as well as Eleazar Daniel have rendered 

 to my brothers and myself during more than two successive years. 



Throughout my journeys during the past cold season I was most 

 obligingly assisted by all the officers in the different stations, so 

 that I was able to carry on my operations without any delay and 

 to collect much valuable information and scattered observations. 



I intend to leave Bhooj on the 17th March and to proceed by 

 Rajkote and through Kattewar to Surat and Bombay, which I shall 

 leave by the end of April so as to return to Europe in conformity 

 with communications made to Government when leaving Eawul 

 Pindi. 



Magnetic Observations. 



I was provided during my journeys with an universal Mag- 

 netometer, by Barrow, with which, however, only the declination and 

 vibration could be ascertained with that accuracy and precision, 

 which these delicate observations require. 



My Magnetometer had been carefully compared at Eawul Pindi 

 with the larger instruments of my brothers ; but the absolute 

 values though easily ascertained by a repeated comparison and by 

 detailed calculations cannot be given at present with the full 

 details. 



The declination and horizontal intensity have been observed at 

 the following localities : — 



1. Shupore. 4. Sehwan. 



2. Mooltan. 5. Kurrachi. 



3. Shikarpore. 6. Bhooj. 



Before my departure another set will be made at Bombay for 

 comparison with the Bombay Observatory. 



Meteorology. 



Besides the daily registering of the temperature of the air, (dry 

 and wet bulb) and the pressure of the air, whilst on the march, and 

 a longer series of observations in all places where I halted for some 

 time, particular attention was paid to the following phenomena : — 



1. Dew. — The quantity of dew which fell at night time was 

 directly and carefully measured in many localities by exposing and
