The application of these, as of all series of the same kind, to the 
construction of tables, is attended with grave inconvenience. This 
is well seen in the case of the series for the sines themselves ; for 
although those be so convergent as to be applicable for any value 
of the arc, it is less laborious, and much more exact, to deduce the 
values of the sine from its well known properties. In the present 
case the convergence is so slow that the series can only be used for 
small arcs. 
The computation of the canon of logarithmic sines by their help 
alone, would entail more labour than the simple plan of deducing 
the logarithm from the sine, even although we counted the making 
of the two previous canons as part of the work.

M.A. Oxon. 
It is frequently remarked that the science of statistics, in its 
various branches, is, like the law, gloriously uncertain,” and 
accordingly, it is alleged that, from the same set of figures, two 
intelligent men can draw very different conclusions. The same
