one whose work is a labour of love. The Museum was at that time 
of very small dimensions, and its imperfections were so numerous as 
to give Mr. Denny plenty of scope for his ardour for long years to 
come. Wherever he found missing links in the collections he never 
rested until he had obtained some object that would help to make 
the chain complete : and in this way the work continued for a period 
of 45 years ; the indefatigable Curator never was so happy as when 
acquiring some fresh object to add to the collections which constitute 
one of the most extensive of our provincial Museums. 
Of his publications, the most important and extensive was the 
"Monographia Anoplurarum Britanni?e," which is an illustrated 
monograph of the British species of parasitic insects, (Lice), belonging 
to the group Anoplura of Leach. This almost untrodden path in 
entomological science Mr. Denny made almost entirely his own in 
this country, and a large proportion of the British Anoplura were 
described and figured by him for the first time. In the preface of 
his Monograph he states that during its progress he had to contend 
with repeated rebukes of his friends for entering upon the investi- 
gation of a tribe whose very name is sufficient to create feelings of 
disgust. The preparation of this treatise occupied his leisure hours 
for a period of fifteen years, the idea being first conceived in 1827, 
and the work published in 1842. During its progress the amount of 
material to be dealt with increased to such an extent beyond what 
was calculated upon, that the publication of the work at the prices 
originally announced in the prospectus could not be carried out 
without serious loss. While in this dilemma the British Association 
met at Glasgow, and on the proposal of Sir William Jardine, a grant 
of £50 was made for the purpose of furthering our knowledge of the 
British Anoplura. Sir William Jardine, Mr. W. Yarrell, Dr. Edwin 
Lankester, and Mr. P. S. Salby were appointed trustees in connection 
with the grant, and the sum was placed at Mr. Denny's disposal. 
The work is illustrated by highly magnified figures, drawn and 
engraved from nature by the author, who was a gifted draughtsman, 
and frequently prepared illustrations for the transactions of the 
Societies with which he was connected. Among other things he 
executed plates for Kirby & Spence's well-known Introduction to
