At the present time, some of the compounds which we have described are 

 under investigation at Port Hueneme; Dr. .'alton Smith of the i'arine Lab- 

 oratory, Uni-'ersity of i'iami, has generously offered to study the action 

 on blocks treated with some of these materials in the accelerated testing 

 procedure which has been developed in his laboratory. 'e are especially 

 grateful to Dr. Smith and his colleagues for this work and to Mr. Robert 

 J. Brotherton of the Basic Sciences Research Department, Ui S. Naval Civil 

 Engineering Research and Lvaluation Laboratory for the microanalyses on 

 the new compounds which vrere synthesized,
