 years, owing to certain defects in the instrument no sjstematic observations were 

 made till late in 1907, when a new collimator magnet was received from the National

 results for February to November, 19U8, those being the o.ly observations on which 

 any reliance can be placed." (Thtse results aie tho.se shown in above taljle.)
