ROGERS AND McLEOD ON THE 



Residuals Derived fkom the Various Solutions. 



The residuals given on the following pages have been obtained by substituting in 

 the equations given on page 145-151 the values of à.T, a, and c, derived from the various 

 solutions. The residuals tvr are given for all the solutions in which the weight factors 

 have been ajjplied.
