248 Bibliotheca Indica publications. [Dec. 



The Chairman read the following extract from a letter from the 

 Librarian of the Johns Hopkins University, Baltimore, regarding the 

 usefulness of the Society's Bibliotheca Indica publications. 



" I feel it due to your Society that I should express more fully 

 than by a mere formal acknowledgement the gratitude of this Univer- 

 sity for its munificent gift of its publications, and especially the volumes 

 of the Bibliotheca Indica. These Sanskrit and other Oriental texts are 

 of the highest value to us. The volumes, as completed, are strongly 

 and handsomely bound, and pass at once into the hands of our Orient- 

 alists ; so that they are fulfilling the purposes which your Society is 

 organized to promote."

(Abstract.) 



The present paper deals with certain interesting features of the 

 temperature of the hill and plain districts of Northern India during the 

 cold weather which were very strikingly exhibited in the month of 

 January, 1889. Ou eleven nights during that month the minimum or 

 lowest night temperature was higher at the hill stations in Upper India 

 (average elevation 7000 feet) than at the plain stations at an average 

 elevation of 1000 feet. On the night of the 3rd January the minimum 

 temperature at Murree, Simla and Chakrata was from 1° to 12° higher 

 than at all stations in the plains of the Punjab, Bajputana, Central 

 India, the greater part of the Central Provinces, the North-Western 

 Provinces, Behar, and the greater part of Bengal (including Calcutta) » 

 The paper is in part devoted to an explanation of this widely extended 

 and remarkable inversion of the normal vertical temperature relations. 



An analysis is given of the temperature conditions prevailing in 

 the hills and plains in different types of weather. It is pointed out 

 that there are three marked types of weather in January, &c, viz. : — 



(1). Pine clear weather accompanying ordinary anti-cyclonic con-
