 Development". It took place at the University of Hawaii, Hono- 

 lulu on May 27-29, and was organized by Dr. R.E.Kane; it had 

 about 25 participants. The second Symposium was entitled "Col- 

 loque International sur le Developpement du Memore". It was or- 

 ganized by Professor Ph.Sengel, and was held at the University 

 of Grenoble from August 28 till September 1; it had 39 invited 

 participants from seven countries, and l8 observers, most of them 

 from France. 



The Vllth International Embryological Congress, in conjunction 

 with a General Assemoly, will be held in Montreal on August 19- 

 24, 1973. It will be devoted to the general topic of the role of 

 the cell surface and cell interactions in growth and development.

 Organizing Committee. The local Organizing Committee is chaired 

 by Professors R.Gagnon and B. Messier, Department of Anatomy,
