148 Treubia Vol. Ill, 2. 



A description of the eggs and larvae of Fistiilaria serraia Cuv., and 

 of Chirocentriis dorab (FORSK.) by Dr. H. C. Delsman has already appeared 

 in "Treubia", Vol. II, Livr. l, p. 97-108 and Vol. Ill, Livr. 1, p. 38-46. 



Also the results of the marine fish pond investigation have been 

 already published in 'TREUBIA", Vol. II, Livr. 2-4, p. 157-400. 



The numerous temperature and salinity figures collected and prepared 

 by Mr. K M. VAN WEEL are at the moment in the press, while the 

 results of the remaining investigations referred to above will be published 

 as soon as possible. 



I would remind foreign naturalists who may wish to come to work in 

 the Laboratory for Marine Investigations that Batavia with Buitenzorg, 

 so close to it, forms an important scientific centre. 



Besides "'s LANDS Plantentuin" and the institutions of the Depart- 

 ment of Agriculture, Industry and Commerce devoted to the realms of 

 applied natural science in Buitenzorg, there are, as far as Batavia is 

 concerned, The Royal Society of Natural Science of the Netherlands Indies; 

 the Royal Magnetic and Meteorological Observatory ; both the Civil and 

 Military Medical Laboratories, and the Head Office of the Department of 

 Mines, etc.. These, and similar institutions or at any rate the publications 

 issued by them, are known to many outside the Netherlands Indies. 



The library of the Department of Agriculture, Industry and Commerce 

 at Buitenzorg and that of the Royal Society of Natural Science at Batavia, 

 will often be of the greatest use to those investigators who visit Batavia. 



Batavia can, in all respects, be called a great town. 



Some of the big hotels there will be able to satisfy every want of a 

 traveller; besides which there are in this town many large European 

 shops, very good clubs, excellent hospitals, etc., etc. 



Batavia is also one of the very few places in the far East where it 

 is possible to hear really good classic music. 



I think I may, in fact, state it is sufficiently v/ell known that Batavia, 

 and the whole of Java as well, has much that is interesting and beautiful 

 to put before the stranger who cares to visit our shores. 



The cost of living in Batavia is not particularly dear; in fact, at the 

 moment (September 1922), it is not necessary to pay more than 175 

 Netherlands East Indian Guilders per month for a very decent room with 

 complete board (with very good food). Moreover, prices are still going down. 



In the largest hotels the charge is, at the moment, from 300 to 500 

 Netherlands East Indian Guilders per month with everything included 

 For 500 guilders per month one gets there a roomy well furnished sitting- 

 room with private front verandah, a bedroom with bathroom and offices 

 attached, telephone, light, service, and full board.
