500 THE DUBLIN MUSEUM OF SCIENCE AND ART. 



BOTANICAL DIVISION. 



This has been greatly developed during the past few years, and it occupies 

 five rooms. 



Room I. is the Index Room to help botanical classes ; in the v^all cases 

 there are specimens, models, and diagrams illustrating the classification of 

 the Vegetable Kingdom (recent and fossil), the life-history of the different 

 groups of plants (root, stem, leaf, flower, fruit, germination) ; botanical terms 

 with definitions of the same ; coloured drawings and specimens as types of 

 the chief natural orders. 



In the floor cases are collections of dried plants of economic or general 

 interest. 



Rooms II. and IV. contain the Economic (Botanical) Collection, the 

 specimens being arranged systematically in their natural orders. 



1. Specimens of plants and parts of plants (raw and manufactured) 

 of economic importance, e.g., the varieties of willow rods and other illus- 

 trations of the Osier industry, Potato-tubers, Turf, Kelp, Flax, Tea, 

 various kinds of Timber, Fungi causing diseases of plants, etc., etc. 



2. Specimens of Fossil Plants. 



The Economic Collection will, it is hoped, contain ultimately a complete 

 illustration of: — (i) All Irish industries into which plants largely enter; 

 (2) such plant industries as might with advantage be carried on in Ireland ; 

 and (3) food plants and other plants of more general interest. 



The collections are for general consultation, and are intended to be of use 

 in the development of the industries of Ireland. 



Room III. is the Herbarium. This room contains dried plants, illus- 

 trating the flora of different parts of Ireland and Great Britain, and less 

 completely of other parts of the world. The chief object of the Herbarium 

 is to be of use to students interested in Systematic Botany, including Field 

 Botany in Ireland, and to those wishing to consult the collections in con- 

 nection with Economic Botany. 



The Herbarium contains a small Working Library, Microscopes, etc. 



There is also a large collection of named drugs of use to pharmaceutical 

 and medical students. 



GEOLOGY AND MINERALOGY. 



The general MiNERALOGlCAL COLLECTIONS are in cases round a map of 

 Ireland raised in relief, and coloured geologically, and there is also a good 

 collection of Irish Minerals arranged according to counties, and of the Irish 

 stones used for ornamental and building purposes. 



There is also a collection of Irish Rocks and Fossils gathered and 

 arranged by the Officers of the Geological Survey, with a series of coloured 

 drawings to illustrate Geological phenomena. 



INDUSTRIAL COLLECTION. 



The Mechanical, or, as usually called, Industrial, Collection, is at 

 present very small ; but it contains a variety of looms and several fine 

 models of factories and manufacturing plants. Great pains have been
