4. — The evidence of past Glacial Action in the Naga Hills, Assam. — By 

 Major H. H. Godwin-Austen, F. R. G-. S., F. L. S., &c. 



(Abstract.) 



In this paper the author points out that on so low a latitude as 25° 

 30' N. glaciers of considerable size must have once filled the valleys of the 

 Burr ail Range. The moraines observed are to be seen under the highest 

 part of the Burrail, where it attains an elevation of 9,890 ft. The thick 

 deposits of boulders and clay in the upper sources of the Barak were also 

 attributed to the greater size of the river during the same period. 



Mr. W. T. Blanford remarked that at the time when glaciers existed 

 in the Burrail, that range was probably much higher than now, but since 

 reduced by the effects of denudation. 



The paper will be published, with illustrations, in Part II of the Journal. 



5. — Photography in connection with the Observation of the Transit of 

 Venus at Boorkee, December 9th, 1871. — By Gapt. J. Watekuouse, 

 Asst. Surveyor General of India. 



(Abstract.) 

 The author, after briefly stating the object of photographic obser- 

 vation of the Transit, gives an account of the experiments undertaken to 

 find a suitable dry process and states the formula for the coffee-albumen 

 process with which the best results were obtained. The instruments used 

 and the photographic arrangements of the observatory and dark-rooms are 

 described. The reasons for discarding the dry process and adopting the 

 wet are stated and an account given of the operations on the day of the 

 Transit. In conclusion, suggestions arc made with regard to the photographic 

 observation of the Transit of 1SS2.
