TABLES. 
I. Numerical Coefficients, for a revision of Gauss’s Allgemeine Theorie, pp. 386 & 387. 
II. General Tables of the Values entered in the Maps (Plates XXII. to XXIV.), pages 
388-416. 
Note. — I n the vicinity of the Great Glacier, where the Southerly progress of the Ships was arrested, and 
many days were passed in the endeavour to discover some channel by which a further advance might be made, 
the rapid convergence both of the geographical meridians and of the lines which represent every 10th degree 
of Declination has made it desirable to depart, in the Map of the Declination, from the practice which has been 
generally followed elsewhere in the Map, of inserting the mean of each day’s observations in the geographical 
position to which it corresponds. In the “ General Tables ” the daily means in this part of the voyage are 
inserted as usual; but in the Map the number of entries in latitudes exceeding 75° S. has been reduced by 
combining the observations in larger groups. The manner in which this has been done is shown in a small 
subsidiary Table in page 391, where the small letters a, b, c, &c., referring to the results characterized by the 
same letters in pp. 389 and 391 of the General Tables, supply the requisite connexion between the Tables and 
the Map.
