THEC iba Foundation, a unique international institution, owes 
its inception to the generosity of CIBA Limited, Basle. However, 
being  established under British trust law, it enjoys complete 
independence in practice and policy. 
Under  the  guidance  of  its  distinguished  Trustees,  the 
Foundation offers accommodation to scientists from all  over 
the world at its home in Portland Place. Foremost in its activities 
is the organization of small conferences, the proceedings of which 
are published in book form in the manner of the present volume. 
The  Foundation  convenes  many  other  informal  discussions 
between research workers of different disciplines and different 
nationalities and each year invites an outstandmg authority to 
deliver  a  special lecture.  An  exchange  programme  between 
French and British postgraduates is  conducted and a  library 
service is available. Furthermore, the Ciba Foundation attempts 
in every other way possible to aid scientists, whether they be 
Nobel Laureates or young graduates making their first original 
contribution to research. 
The purpose of the Ciba Foundation, which is to promote 
international co-operation in medical and chemical research, is 
symbolized in the armorial bearings by  five interlaced rings 
representing the continents, a black sacrhcial cock (emblem of 
Aesculapius) holding  a  medical  caduceus,  and  three  regular 
hexagons for chenlistry. Its domicile in London is indicated by 
the red sword of St. Paul and the British lion; the wyvern and 
the crozier, symbols associated with Basle, refer to the sponsoring 
firm located in this ancient Swiss town.

PREFACE 
THISfi ftieth major volume published by J. & A. Churchill 
Ltd. for the Ciba Foundation appropriately contains the tran- 
sactions of a special symposium, arranged in celebration of the 
tenth anniversary of the opening of the Ciba Foundation by 
Sir Henry Dale, O.M., in June 1949. 
From Professor A. von Muralt had come the suggestion that 
it would be interesting and probably valuable to consider the 
more important and distinctive advances in research over the 
ten-year period. To make such contributions debatable, in the 
manner of informal discussion customary at the Foundation, the 
Director invited  his  programme  speakers to  pick  out  those 
developments in the past ten years which they believed would 
prove to be most significant in the next ten years. 
It was rather widely felt that so diverse a group of specialists, 
however talented, would not enjoy or discuss papers thought 
to be outside the range of their own main interests. A decisive 
factor in overcoming any inhibitions of this kind was the accept- 
ance by Sir Harold Himsworth of the chairmanship of the whole 
symposium.  The  youthful  Ciba  Foundation  was  singularly 
honoured in this way by  Sir Harold and by all the eminent 
international scientists-seven  of  them  Nobel Laureates-who 
gathered in London for the three days and so co-operatively 
joined in the give and take of facts, interpretations and specula- 
tions about a diversity of medical research at the time of this 
minor celebration at the Foundation. 
The Foundation’s three Editors have joined in preparing this 
fiftieth volume for publication. There can be no better moment 
to record with happiness the partnership with Mr. J. and Mr. J. A. 
Rivers of J..&A  . Churchdl Ltd. for the ten years since this old 
and honourable firm of medical publishers accepted at their own 
risk the publication of the Foundation’s first volume.
