 1059-1063. 



Describes a technique for anesthetizing sea lions, and the configuration of a 

 unique restraining cage which enables the animal to be examined, treated, or 

 anesthetizetl without harm to either the sea lion or the handlers.

Simpson, J. G. and W. G. Gilmartin 1970 An investigation of elephant 

 seal and sea lion mortality on San Miguel Island. Bio-Science, 1 March 1^70, 

 P. 289. 



At the request of state and federal authorities following the Santa Barbara 

 oil spill, an investigation was made to determine if oil washing up on San Miguel 

 Island had affectetl any of the seals and sea lions there. No evidence was found 

 of illness or mortality attributable to the oil.

HYDRODYNAMICS 



Lang, T. G. 1966 Hydrodynamic analysis of dolphin fin profiles. Nature 209 :110- 

 111. 

 Cross sections of dolphin fins were found to have a shape intermediate be- 

 tween independently proposed hydrodynamic shapes believed to have superior 

 characteristics.

 Lang, T. G. and K. S. Pryor 1966 Hydrodynamic performance of porpoises 

 (Stenclla attcnuata) Science 152 :531-533. 

 The above two papers describe open ocean speed runs of trained porpoises. 

 Top speeds recorded were 16.1 knots (Tursiops gilli) and 21.4 knots (Stenella 

 attenuata). The results compared closely with highest predictions based on rigid 

 body drag calculations and estimated available power output.
