plugs serving table lamps where they are most useful whilst having regard to 
economy. 
It will suffice to mention that each research room is provided with (a) a 
central drop-light that can be moved up and down above the writing table, 
(b) a bracket-light above the sink, (c) a bracket-light above the short arm of 
the L-shaped bench used for the embedding bath, etc., ( d) two plugs to table 
lamps on the work bench, these supplying two or four lamps as required. The 
bracket-lights are placed at a height of about 3 feet above the bench or sink. 
The drop-lights are J-watt, 60-candle power, the others 30 c.p. throughout; 
the corridors are lit by 30 c.p. fixed drop-lights, corresponding lights in the 
research museum being 60 c.p. The wiring is all carried in flattened lead pipes 
attached to wooden strips, the pipes being protected by iron guards where 
liable to injury, this method of wiring having various advantages over that 
in which iron pipes are used for carrying the insulated wires. 
Electric power plugs have been placed in five situations: the sterilizing 
room, chemical and photographic rooms and research museum. 
Equipment. The Institute is well provided with all requisite apparatus 
including modern appliances for the study of the biology of parasites. Special 
attention is being given to securing facilities for the study of the best and most 
recent methods of conducting research in parasitology. 
Scientific Collections. 
The collections of the Institute comprise numerous specimens acquired 
by the writer during many years, others presented to the Quick Laboratory 
and more recently to the Molteno Institute. The collections are intended 
primarily to aid the workers at the Institute and are housed in the research 
museum, the latter affording space for the considerable expansion of the collec¬ 
tions which is expected in the future. 
The collection of Ixodoidea, which is the mast valuable at present, is one 
of the largest existing, besides being rich in types. There are many specimens 
of blood-sucking and parasitic insects and acari. The helminthological collec¬ 
tion is rapidly growing in value, and, like the preceding, comprises types. 
Protozoological and mycological specimens are being steadily acquired, and 
there is a bacteriological cabinet. We hope to augment our collections by 
means of exchanges and through the further generosity of donors in different 
parts of the world. 
A considerable amount of illustrative material, largely original, including 
diagrams prepared for the purpose of instruction in parasitology, is already 
contained in our museum. 
Portraits of scientific men. A collection of about 300 portraits of those who 
have distinguished themselves in the domain of parasitology has been gathered 
by the writer and presented to the Institute. The portraits are mostly framed 
and hung chiefly in the well-lit corridors, the grouping being by nations and 
as far as possible by subjects. A number of these portraits are being published
