official governmental reports. First, because in this way the information 

 radiates more rapidly to a wider public ; thus each of the two chemical 

 journals just mentioned has more than 5,000 registered readers. Secondly, 

 because this form of publication is frequently preceded by a reading and 

 discussion of the subject-matter at a scientific meeting, and lastly because 

 the financial circumstances of the learned societies compel them to impose 

 a limit on the length of communications which is conducive to brevity and 

 conciseness. 



Relations with other Scientific Institutions. 



Apart from substances of therapeutic interest prepared for the Com- 

 mittee on Chemotherapy, numerous other research materials have been 

 distributed to colleagues in the universities and research institutions. 

 Compressed helium and carbon monoxide have been rendered available 

 for scientific workers requiring these gases. Organic derivatives of 

 tellurium have been lent to the Cambridge University Chemical Laboratory 

 for the purpose of physico-chemical measurements, and to the Birkbeck 

 College for the demonstration of the parachor of this element. Com- 

 pounds of special chemical interest have been supplied to the Davy 

 Faraday Laboratory and to the National Physical Laboratory for the 

 X-ray study of their crystal structure. It is a pleasant duty to refer to 

 the aid received from the Government Laboratory in respect of micro- 

 analyses and in connexion with the work on synthetic resins. 



Eeference has already been made to the close collaboration of the 

 laboratory with H. M. Fuel Research Station in regard to the products of 

 coal carbonisation. Certain preparations from low temperature tar have 

 been submitted to the Cotton and Woollen Research Associations, for 

 examination in connexion with the chemical treatment of textile fibres. 



Relations with Chemical Industry. 



The associations of the laboratory with chemical industry have always 

 been cordial and are daily becoming increasingly intimate. Prominent 

 industrialists either individually or in their corporate capacity as members 

 of the Association of British Chemical Manufacturers and allied organisa- 

 tions have visited the laboratory and sometimes repeatedly. 



Arising out of these visits and informal conferences, more than a 

 hundred samples of the research products of the laboratory have been 

 distributed to interested enquirers. 



Members of the scientific staff participate in the work of the Com- 

 mittee for the Standardisation of Tar Products Tests, the Bureau of 

 Chemical Abstracts, the Corrosion Committee of the Iron and Steel 

 Institute, and the Council and various Committees of the Society of 

 Chemical Industry. 



Although the laboratory is not a teaching institution in the academic 

 sense of the term, yet facilities have been afforded for collaboration in 

 research to chemists in training of approved qualifications. The two 

 leading metropolitan gas companies have seconded to the laboratory for 

 this purpose junior members of their scientific staffs who have worked at 

 Teddington for periods ranging from six to eighteen months. The 

 subjects so far selected for this collaboration have been high-pressure 

 -chemistry and low temperature tar.
