of votes of the present fellows and subsequent ratification by all fellows. The 

 number of fellows is limited to 75. 



Candidates for membership are usually recommended to the Board by two 

 fellows. The fellows should have previously convinced themselves that their 

 candidates like to join the I. I.E. Candidates for membership can however just 

 as well come forward directly or can be suggested by one of the members of the 

 I. I.E. In that case the Board should however be requested to ask for recom- 

 mendation among the fellows before or at the next General Assembly. After 

 subsequent approval of the Board candidates for membership are elected by 

 the General Assembly by majority of votes. 



In order to maintain certain standards it has been decided at the General 

 Assembly in Providence in 1956 that candidates for membership should have 

 been active in the field of morphogenesis for at least 10 years or, in case of 

 a shorter period, should have made important contributions in this field.
