Material. 
The foregoing research has been prosecuted on 91 mammals at 
present housed on the store-rooms of the Anatomical Laboratory 
of the University of Manchester. My thanks are due to Professor 
ELLiot SMITH for so kindly placing them at my disposal. I am also 
very much indebted to Messrs. JENNISON of Belle Vue Zoological 
Gardens who have generously presented the majority of them to the 
Department.
