By combination we have — 



From mean of observations at Cambridge, (R — M) cos 8 = +0.144. 

 From mean of observations at Montreal, (R — M) cos S = +0.103, 



Arranging the results in the order of declination, we have — 



It appears from these results that there is a slight diminution of the value of the 

 equation corresponding to an increase of the declination of tlie star observed. 



The clock comparisons for the difference in longitude will appear in the report of 

 Professor McLeod, also the observed data for the determination of the longitude by 

 star transits. By arrangement with Professor McLeod, he will undertake all the work 

 involving the definitive determination of the longitude from the data obtained at the 

 two station.s.
