Sibbald observes that " the superior part of the body was swelled 

 to a prodigious size. In length it was 52 or 53 feet, its height 

 12 feet, its girth above 32 feet. Its head was so large that it was 

 (the tail being removed) half the length of the whole body. In form 

 it was oblong-round, somewhat compressed at the upper part ; in- 

 ferior part of rostrum beyond lower jaw 2^ feet, the superior part 

 nearly 5, Lower jaw 10 feet long. The extreme part of the ros- 

 trum was distant 12 feet from the eyes, which were very small for 

 the size of the head, about the size of those of the haddock. A little 

 above the middle of the rostrum is a lobe, which is called the ' lum,' 

 with two entrances covered with one operculum, called the ' flap.' 

 The size of the cranium may be estimated by the fact that four men 

 were seen inside it at one time, extracting the brain, which con- 

 tained several cells or alveoli, like those which bees keep their honey 

 in, and in these were round masses of a white substance, which, 

 upon examination, were proved to be sperm. Some of this substance 

 was also found externally on the head, in some parts to the thickness 

 of 2 feet. In the superior jaw Avere 42 alveoli, hollowed out for 

 receiving the teeth of the lower jaw ; they were of a cartilaginous 

 nature. In the inferior mandible there were 42 teeth, 21 on each 

 side, all of the same form, which was like that of a sickle, round 

 and a little compressed, thicker and more arched in the middle, and 

 gradually becoming thinner, terminating siipcriorly in an acute cone 

 turning inwards ; inferiorly it becomes thinner, and terminates in a 

 more slender root, which is narrower in the middle. Of these teeth
