PREFACE 



The Ciba Foundation held a symposium on transplantation of 

 tissues in 1953 and there have been many conferences elsewhere in 

 recent years, notably in Paris in 1957 and in Liege in 1959. This 

 subject's "take" is so vigorous that fresh material for a further 

 international conference in London in 1961 would clearly soon 

 be abundant, and Professor Medawar had already arranged this 

 with the Director before his Award of the Nobel Prize set the 

 seal on this project. 



The Foundation itself suffered transplantation on this occasion ; 

 our own building being closed for reconstruction, we were 

 fortunate to be accepted as a graft by the noble and ancient 

 Society of Apothecaries, through the courtesy of its Master, 

 Mr. A. M. A. Moore, and members of the Court. We are deeply 

 indebted to them, and to the Society's staff. The graft was 

 temporary, but we hope that the comparatively infant Foundation 

 may prove that it is for ever tolerant to any call made upon it by 

 our generous hosts of the Society. 



The enthusiastic contributors to this volume, and its editors, 

 hope that its publication will provoke a proliferative response in 

 readers concerned with this complex and rapidly developing 

 subject.
