Blakeney and the other officers of the department
for the accuracy with wdiich they kept us supplied
Avith the latest scientific periodicals, and Avith such
instruments and books of reference as Ave required.
This account may perhaps appear unnaturally
couleur de rose, still, looking over it again, I can
detect no exaggeration. There is of course anotlier
side to the picture. The Avork was done Avith the
regulation expenditure of tissue; the strain both
mental and physical Avas long and severe, and it
has told a good deal upon all of us.
