Of the plants which have already been established in the remainder

 Vahl, Barringtonia asiatica KURZ, Calotropis gigantea Dryand, Casaarina

West of the pond is a low hillock composed of coral blocks and 

 coral sand, where it is the intention to plant out such plants as : — Canavalia 

 lineata D.C., Crinam asiaticum L., Euphorbia atoto FORST., Ipomoea pes- 

 caprae ROTH., Spinifex littoreus MERR., etc.. 



The height of the spacious and airy rooms is 4^2 Metres; gas, town 

 water and electricity are available in all the rooms. 



The strangers' work room, whose measurements are 10.5 M. by 6 M, 

 (see 7, Plan No. 2), has, if necessary, sufficient room for five investigators ; 

 the chemical laboratory alone is at the moment (September 1Q22), not yet 

 installed.' 



Photo No. 1 gives a view of the front (North side) of the main building. 



Photo No. 2 gives a view of the office of the Chief of the Laboratory 

 (Room 1, Plan No. 2). Through the open door in the background, one 

 looks into the laboratory of the Chief (Room No. 2, Plan No. 2), the North- 

 West corner of which is to be seen on Photo No, 3. 



Photo No. 4 shows two of the five working tables in the strangers' 

 work room. 



It can be seen on Photo No. 1 (cf. second window from the left), 

 that the top two-thirds of a number of shutters, and of all glass windows, 

 can be opened and shut independently of the lower third. 



Whenever the upper two-thirds of the ventilating portion of the 

 shutters is shut, the eyes of a person who is working at a table just in 

 front of a window, are sufficiently protected from the often unbearably 

 strong high light, while the reflector of the microscope can yet receive 

 enough illumination direct from the sky. 



On the other hand, the closed under third portion of the glass window 

 can, if necessary, protect the work table and the . investigator himself 

 against the strength of the sustained sea winds. 



The foundations of the building are of reinforced concrete on which 

 a teak framework is erected; the open spaces in the wooden framework
