plemented and not replaced by references

“ Such editions as that of which Prof. that all points of syntax or of Ciceronian 
Mayor has given us the first instalment will 
doubtless do much to remedy this undeserved 
neglect. It is one on which great pains and 
much learning have evidently been expended, 
and is in every way admirably suited to meet 
the needs of the student The notes of 
the editor are all that could be expected 
from his well-known learning and scholar- 
ship. .... It is needless, therefore, to say

thing is slurred over, nothing extenuated. 
We learn exactly the weaknesses of the 
theory, and the direction in which the com- 
pleter theory of the. future must be sought 
for. The same spirit pervades the papers 
on pure mathematics which are included in 
the volume. They have a severe accuracy 
of style which well befits the subtle nature 
of the subjects, and inspires the completest 
confidence in their author .” — The Times. 
“ The volume of Professor Stokes’s papers 
contains much more than his hydrodynamical 
papers. The undulatory theory of light, is 
treated, and the difficulties connected with 
its application to certain phenomena, such as 
aberration, are carefully examined and re- 
solved. Such difficulties are commonly passed 
over with scant notice in the text-books..,. 
Those to whom difficulties like these are real 
stumbling-blocks will still turn for enlighten-
