Dear Sir. 



I send you to-day a copy of a recent book on the prevention of 

 malaria in the Federated Malay States by Dr. Malcolm Watson. 



This book has been published by subscriptions from a number of 

 Companies shown on a special page, and will be of great importance 

 for the prevention of malaria in all rubber and other estates in the 

 East. It has been suggested to me that members of your Associa- 

 tion miffht like to buy copies, and I therefore inform you that they can 

 be obtained from this laboratory at the price mentioned, namely 7/6. 

 I also send you a number of advertisement slips of the book, which 

 you might like to issue to your members. Mr. Eric Muller, of the 

 Anglo-Malay Rubber Co., has suggested my writing to you. 



Believe me, 



Yours faithfully, 

 Ronald Ross, 

 Professor of Tropical Medicine.

Dear Sir, 



We make free to address you on the subject of the Quarantine 

 expenses incurred by Estate coolies arriving from India through the 

 Straits Immigration Department, which expenses as you are no doubt 

 aware are payable pro rata per head of coolie by the Estates receiving 

 such coolies.
