11. Fifth volume of Hope Reports. 
By the middle of the year it became evident that the 
accumulation of separata rendered it expedient to issue a fifth 
volume of Reports. The volume, dated June 25, 1906, is 
considerably larger than any of those which preceded it. It 
contains reprints of papers published 1903-1906, although 
many of those which appeared in 1903 formed part of the 
fourth volume, while the great majority of those published in 
1906 are reserved for the sixth volume. This latter should 
appear in the course of the present year. 
12. Exchange of Hope Reports with the publications of 
Foreign Entomological Societies. 
The number of Entomological Societies all over the world 
which sent their publications to Professor Westwood, rendered 
the Hope Library extremely efficient in this, the most im- 
portant part of the literature of a science. After his death 
at the close of 1892, nearly all these series, in many cases 
complete from the commencement, came to an end, for the 
income of the Department was quite unable to bear the heavy 
expense of purchasing so many annual publications. Although 
it was obvious that the difficulty would increase with every 
year in arrear, the Professor hoped that it might be possible 
in the future, as the work of the Department developed, to 
arrange an exchange of publications. The appearance of the 
fifth volume of Hope Reports in the summer of 1906 seemed 
a suitable stage at which to enter upon negotiations. The 
Entomological Societies of Berlin and Stockholm were ap- 
proached, and courteously consented to exchange their 
publications from 1893 to 1906 inclusive for the 5 volumes 
of Hope Reports, and hereafter to exchange regularly. In 
the case of the Berlin Society with the more extensive 
publications, a very moderate payment was asked for half 
the years in arrear. The Professor desires to acknowledge 
the extremely generous manner in which the Hope Depart- 
ment was treated by these two Societies, and to express his
