6. In the course of the last 19 months, more particularly since May i last, 

 I have been engaged at the British Museum or at home on the Vulgate Ver- 

 sion in transcribing the unique second part of the manuscript No. 337 of the 

 Bibliotheque Nationale. Having recognized the importance of this manu- 

 script in regard to the genesis of the Vulgate Version, I had its unique 

 portion photographed in December, 1907, on a considerably reduced scale, 

 because it is still only accessible at the Bibliotheque Nationale. Of these 

 photographs (to the number of 180, each representing 4 closely written 

 columns of 45 lines each, i. e., 720 columns) I have so far completed 600. 



In order to enable you to form a clear estimate of the present state of my 

 work, I beg to add an account of what I have still to do to complete it : 



1. Revise preliminary matter to volume I. 



2. Revise about 380 pages of volume III for the second time, add side 

 notes and head lines. 



3. Revise about 139 galleys of volume IV for the first time, for the second 

 time, and add side notes and head lines. 



4. Revise first and second times the whole of volume V and add side notes 

 and head lines. ''^=3 



5. Transcribe, collate with four manuscripts, prepare for press, revise first 

 and second times, provide side notes and head lines to all of volume VI. 



6. Compile general index raisonne of names and places to the 6 volumes. 



METEOROLOGY. 



Bjerknes, V., Christiania, Norway. Grant No. 551. Preparation of a work 

 on the application of the methods of hydrodynamics and thermody- 

 namics to practical meteorology and hydrography. (For previous re- 

 ports see Year Books Nos. 5, 6, and 7.) $1,200. 



Mr. J. W. Sandstrom left his position as a grantee of the Carnegie Institu- 

 tion in June, 1908, and Messrs. Th. Hesselberg and O. Devik have been 

 chosen to assist in the work. 



The systematic working out of the purely kinematic methods of investigat- 

 ing air or sea motions have been continued and will soon be finished. These 

 being motions in space, special methods had first to be introduced for rep- 

 resenting them by diagrams on plane charts. Two essentially different 

 methods of doing this have been given and tried practically. 



The problem of developing methods for passing from the scattered obser- 

 vations giving the velocity in different points in the atmosphere or the sea to 

 these continuous representations of the motions has been completely worked 

 out and the methods have been tried practically for the case of air motions, 

 the most important observations used being those organized by the Inter-
