264 THE ENTOMOLOGIST. 
on the 5th of October. He died in the most perfect peace of 
body and of mind. For many years Mr. Walker was a 
member of the Linnean and Entomological Societies of 
London, but resigned his membership in both some time 
before the close of his life. 
It might be excusable in a man of such incessant bodily 
activity,—so locomotive by inclination, so devoted to the 
study of Nature in all her aspects, so diligent a collector of 
the objects of his favourite study,—had he allowed his pen 
to rest while his hands were engaged in forming and 
arranging his collections. But this was not the case with 
Mr. Walker, as his Catalogues of the National Collection 
abundantly testify. Of the Lepidoptera Heterocera, alone, 
Mr. Walker catalogued and described upwards of twenty-three 
thousand species; in addition to which he prepared similar 
catalogues, although perhaps not to the same extent, of the 
Diptera, Orthoptera, Homoptera, Neuroptera, and part of the 
Hymenoptera: such an amount of labour, as is testified by 
these catalogues, has seldom, if ever, been accomplished 
by one individual. But this statement by no means 
represents the whole of his literary labours. He contributed 
shorter or longer papers to the Transactions of learned 
societies, and to the periodicals of the day, especially 
to the ‘Zoologist’ and ‘Entomologist;’ by the indexes 
of the latter I find he sent thirteen communications to 
the first volume, three to the second, one to the fourth, 
thirteen to the fifth, and forty-three to. the sixth; during 
the present year his writings appear in every number. I 
intended to catalogue these, and his other labours, to give 
some idea of the number of pages, number of species, and 
dates of each; but I can scarcely now venture to look 
forward to the accomplishment of this labour of love. 
A word remains to be spoken of the man -apart from the 
scientific and accomplished naturalist. Throughout my long 
life 1 have never met with anyone who possessed more 
correct, more diversified, or more general information, or 
who imparted that information to others with greater readi- 
ness and kindness; I have never met with anyone more 
unassuming, more utterly unselfish, more uniformly kind and 
considerate to all with whom he came in contact. It is no 
ordinary happiness to have enjoyed the friendship of such a 
man for nearly half a century—Hdward Newman.
