various nests of Hymenoptera were exhibited in the small 
“show-cases” on the parapet of the gallery, while the bees 
and wasps which had constructed them were found in some 
one of the directions indicated above. 
This sketch suggests the nature and the amount of labour 
—chiefly borne by Mr. Holland—which was necessary in order 
to disentangle one very large collection from another vast 
collection. A large amount of work has also been thrown 
upon Mr. A. H. Hamm by the state of the specimens, hundreds 
of which required to be mended and repinned before they 
could be safely moved and studied. Great age and partial, 
sometimes nearly complete, destruction by the worst forms 
of pests combined to render the task of manipulation extra- 
ordinarily delicate and difficult. The success achieved by 
Mr. Hamm is more complete than could have been hoped. 
As the work proceeded it was often necessary to obtain 
evidence upon the handwriting of Professor Westwood at 
different periods of his life and seek information as to methods 
pursued, assistants employed, &c. In all such inquiries the 
Professor has invariably received the kindest and most efficient 
help from his friend, Miss Swann. 
The interpretation of Spanish and Portuguese words in the 
Brazilian manuscript would have been a great difficulty but 
for the kindness of Senor Don Fernando de Arteaga. 
Many of the data which have now happily been recovered 
could not have been obtained but for the sympathetic help 
of the Director of the Royal Gardens at Kew. Burchell’s vast 
botanical collections and the manuscript notebooks referring 
to them are in the Kew Herbarium, and many a: date and 
locality of importance to the collection of insects could only 
be decided by inquiry at Kew. Furthermore, it was most 
desirable to add the recognized specific names to the plants 
mentioned by Burchell in the records of insects, &c., captured 
on his two great journeys. Botanical names which are 
not now accepted occur frequently ; but through the kind- 
ness of Sir W. Thiselton-Dyer and the staff of the Herbarium, 
the fullest information which could be obtained has been
