Abdominal Viscera . — As the accounts which have been given by 
previous writers of the Stomach in Balcenoptera rostrata vary 
materially from each other, I took the opportunity of securing 
the stomach of the Granton specimen and of submitting it to 
anatomical examination. 
The stomach, along with 14 inches of the oesophagus and the 
commencement of the duodenum, was carefully removed. After 
removal they were inflated, and the exterior of the organ examined. 
Its extreme transverse diameter in a straight line was 5 feet 9 inches, 
and its extreme antero-posterior diameter, also in a straight line, was 
4 feet 2 inches. It was a compound stomach, and an examination 
was made of the number and nature of the compartments. 
The 1st compartment was directed obliquely backwards and to 
the left, and tapered behind so as to terminate in a narrow, rounded, 
blind end, in relation to which the spleen was situated. It 
measured 38 inches from the place where the oesophagus joined 
it to the splenic end, its greatest transverse diameter about the 
middle of the ventral surface was 3 feet 3 inches, and its 
circumference was 6 feet 6 inches. The oesophagus was con- 
tinuous with its anterior surface, and it was observed that at the 
place of junction the gullet was constricted in comparison with its
