D. Appropriation of the Government Grant of 1000 in 1853. 



1 . To Dr. Waller, for investigating the results of the sec- 

 tion of nerves 100 



An interim report of the progress of this investigation 

 has been received by the Royal Society. 



2. To Dr. James Thomson, C.E. of Glasgow, and Mr. 

 Fairbairn of Manchester, for experiments on the friction 

 of discs revolving in water, for the purpose of obtaining data 

 required in calculations relating to turbine water-wheels and 

 centrifugal pumps 50 



The results already obtained have been communicated 

 to the Royal Society, and preparations have been made 

 for renewing the experiments on a more extended scale. 



3. To Captain Lefroy, for the expenses of preparing for 

 publication observations on the Aurora Borealis made in 

 North America 20 



The observations have been in great measure prepared 

 for publication. 



4. To Warren De la Rue, Esq., for mounting the Huyge- 



nian object-glass of 123 feet focal length 250 



This, with an appropriation of equal amount in 1854, 

 was designed to meet an application made to the Royal 

 Society by M. Struve of St. Petersburg, to compare 

 the appearance of Saturn as shown by the Huygenian 

 lens referred to with that of the planet as seen in tele- 

 scopes of modern date ; in consequence of Huygens's 

 representation of the ring not according with its appear- 

 ance as now observed. Difficulties have been met with 

 in carrying out this object in the method first proposed, 

 which have occasioned delay; and the subject now 

 stands for reconsideration. 



5. To Professor William Thomson of Glasgow, for ex- 

 periments on the thermal effects of electric currents in un- 

 equally heated conductors 50 



See note to a similar appropriation in 1852, No. 1.
