mendation of the Grand Duke, by Michele 
Cortazzi.’ 
On his way back to England Owen stayed a 
short time at Cologne, where he made the usual 
visits to the places of interest. At St. Ursula’s 
Church, however, his attention was attracted to the 
bones of that saintly lady’s virgin companions, 
many of which he very soon discovered to be 
those of horses and other animals.*' 
Owen did not reach London till November 5, 
owing to the ‘ fogs on the Rhine,’ which delayed 
him two days. 
On November ii we find him busily at work 
again, for he writes to one of his sisters from the 
College of Surgeons : ‘ Since my return I have 
prepared for press the No. XL of my “Brit. Fossil 
Mammals,” which I hope you will receive at the 
beginning of next month, and I have made some 
progress with the final number, so that work will 
be completed by the end of this year. I have 
next to write and print the volume on “ Verte- 
brated Animals,” which will complete my Lec- 
tures on the Comparative Anatomy of Animals 
generally. I intend to lecture on the Vertebrata 
next spring, so the same work will serve for both 
purposes. These labours don’t depend on bright- 
ness of sky, and I find a vast consolation in them 
for the great change between October in Italy and 
' The tradition concerning" Mtm'ay's Handbook for North 
these bones will be found in Germany.
