348 BOTANICAL INFORMATION. 
Museum of Practical, or Economic Botany, at the Royal Gardens, Kew. 
The contributions of friends have materially enriched this collection 
within the last few weeks. Among some of the more interesting 
additions we may mention specimens of diseased timber (whether oc- 
casioned by insects or other causes) ; and what, at first sight, seem rather 
to belong to the animal than the vegetable kingdom, splendid specimens 
of the nests of hornets and wasps, all presented by the Rev. Professor 
, Henslow : these latter objects are truly paper, made by the insects 
of vegetable fibre. A case is filled with the several implements employed 
by the native Indians of Madras in preparing toddy from the 'T'oddy- 
P 'his will soon be illustrated in our Journal by a plate from a 
drawing presented at the same time with the implements, the gift of 
J. W. Strachan, Esq.,of Teddington Grove. Dr. Hooker has sent from 
Patna a series of drawings illustrative of the cultivation and preparation 
of opium ; and there is now on its way a eonsiderable collection of ob- 
= explanatory of the manipulation of that drug, of which we shall 
e further notice by and by ; and Dr. Pereira has generously added 
wind to the pharmaceutical collection. A large ease is about 
to be entirely filled with the products of ffaz, exhibiting the different 
stages of preparation, and the beautiful textile fabries now so largely 
manufactured in Ireland ; the combined gifts of the * Royal Society for 
the promotion and improvement of the growth of Flax in Ireland,” 
and of Messrs. Storar and Co. of London. 
The Museum is anxious to possess as complete a collection as pos- 
sible of paper, manufactured from different vegetable substances, in 
all parts of the world. The variety of plants that subserve to paper- 
making, throughout the world, is quite remarkable; and a full set of 
such papers would be extremely interesting and instructive. We trust 
our intelligent travellers will aid us in this department, taking eare to 
ascertain the name, or to provide a specimen, of the plant which yields 
the respective tissues.
