Some specimens sent by Dr C. Christy (23 bloods) from Kampala, 

 Uganda, by Mr William Foster (2) from Sapucay, Paraguay, by Dr H. 

 Ainsworth (3), by Captain Flower (1), by the Scottish Antarctic 

 Expedition (5), as well as others (11 specimens) received from the 

 Zoological Society's Gardens, London, unfortunately arrived too late 

 to be included in the present work. They will, however, be utilized 

 in due course. 



My laboratory attendant, Mr Bertie Clarke, has been of great 

 assistance in the routine work connected with this investigation, where 

 so much depended upon conscientious attention to details, and I feel 

 it is but fair to include him amongst those to whom I am indebted. 



The expenses of this investigation have been in part defrayed 

 personally and through two grants, the one from the Government Grants 

 Committee of the Royal Society, the other from the John Lucas Walker 

 Trust, Cambridge.
