Hence the annual decrease of the dip in Dublin (or 8 a) is 

 2'. 38. 



The close agreement of this result with that recently 

 deduced by Major Sabine, from his observations at the 

 Regent's Park, is very remarkable. From these observa- 

 tions it appears that the dip has undergone a diminution of 

 39' at London, in the interval between August 1821, and 

 November 1837, an interval of 16£ years. The annual de- 

 crease, therefore, is 2'.40. 



Resolved, on recommendation of the Council, — " That 

 as a first step towards the attainment of greater regularity 

 of payment by members in future, the five following de- 

 faulters, being deeply in arrear, be now excluded from the 

 Academy, and declared to be no longer members thereof; 

 but, as a measure of indulgence, that they be not sued at 



law for their arrears : 



£ s. d. 



Henry Grattan Douglas, M. D., in arrear, 37 16 



Thomas Little, M. D. . . 37 16 



John L. Arabin, Esq. , 33 12 



Gerard Macklin, Esq. . . 27 6 



William Shaw Mason, Esq. . ■ 23 2 0" 



Resolved, — " That the portion of the By-law, Chapter 

 VIII. Section 4, which forbids the commencement of a new 

 paper after 10 o'clock, be suspended for the present."
