February, 1911.] Vice-President’ s Address, xly 
while the third has traced evidence of Hindu architectural 
ideals in the early Mahomedan Mosques of Bengal. Dr. Satis 
Chandra Vidyabhusana has continued his researches in the fas- 
cinating subject of the history of medieval Indian Logic, and 
the only work extant on Brahminic Logic of the Middle Ages, 
Pariksha Mokshasutra of the Digambar Jains, Nyayavatara of 
Logic, a subject hitherto involved in much obscurity. In this 
connection, reference must be made to an interesting paper on 
Hindu Logic by Prof. Vanamali Chakravarti, in which he dis- 
cusses the various theories concerning the standards of right 
knowledge as laid down by Indian logicians. Of a very different 
character is the Memoir on Monuments in Afghanistan by Mr. 
Hayden, embodying a masterly investigation which cannot fail 
to rouse the interest of all serious students of Mahomedan 
Archaeology. In the field of Arabic and Persian studies also, 
notable work has been accomplished. Moulavi Abdul Wali has 
edited for the first time a complete collection of the Quatrains 
of Abu Said Ibn Abul Khair. of which a fragment only had been 
published in the proceedings of the Munich Academy, thirty- 
five years ago, by Prof. Ethé. Of fascinating interest is the 
collection of poems of Emperor Babur edited by Dr. Denison 
Ross from the interesting manuscript in the library of the 
Nawab of Rampore, which is in part in the autograph of the 
illustrious Royal author. Partly scientific and partly philo- 
logical in character is the contribution by Mr. Stapleton and Mr. 
Azoo in which they give us a study of an alchemical compila- 
tion of the thirteenth century. In the field of the natural and 
physical sciences, there have been numerous papers which treat 
of various points of interest to the investigator, but I trust I 
may without impropriety mention two of these as of special 
value. The report of the Committee on the adoption of a stan- 
dard temperature for laboratory work in India is of the great- 
est practical utility to all scientific investigators in the Tropics, 
and we are indebted to Prof. Bruhl for directing attention to 
crops ; the subject is obviously one of far-reaching interest and 
deserves extended investigation. ; 
There is only one other matter which demands special 
mention on the present occasion. I refer to the work in aid of 
the search for Sanskrit, Arabic and Persian Manuscripts. The 
importance of this undertaking cannot be over-estimated, as
