3Q2 DISCOVERY REPORTS 



ACKNOWLEDGEMENTS 



Grateful acknowledgements are due to the Department of Anatomy of the Medical College of 

 St Bartholomew's Hospital for help in the preparation of microscopic sections and the identification 

 of the histological structures. In this connexion I also wish to thank Dr V. R. Wheatley of 

 the Department of Biochemistry at St Bartholomew's for the chemical analysis shown on p. 299. 

 Acknowledgement is also due to the National Institute of Oceanography, particularly to Dr R. Laws 

 for supervising the collection of the large portion of the skull of Balaenoptera physalus, which has 

 been so useful in the general study of the cetacean ear during the preparation of this account. 

 Finally, I wish to thank my colleague Dr F. C. Fraser, Deputy Keeper, Department of Zoology, 

 British Museum (Natural History) for his collaboration.
