4S4 SCIENCE PROGRESS 



" I have to thank Dr. Woodward and also Dr. C. W. Andrews 

 for the valuable help and advice they have given to me. — 

 B. P." 



Being no palaeontologist by profession (which does not 

 mean that I am ignorant in palaeontological matters) and 

 not having been able to write English at that time (191 6), I 

 invited Dr. Woodward to make a joint-communication on 

 the discovery, and was glad that the eminent palaeontologist 

 accepted it. 



Yours faithfully, 



B. Petronievics.
