A498 CONCLUSIONS. 
B. Facts. 
These are so numerous that | am obliged to bring them together 
under several heads. 
1. EXTERNAL CHARACTERS. 
a. Dimensions. 
The length of what was visible of the animal above the surface 
of the water was estimated to be: from sixteen to eighteen feet 
(25), several meters (136), about twenty feet (150), from twenty 
to thirty feet (35), thirty feet (118, 123), about thirty-six feet (92), 
about forty feet (26, 41, 42, 44, 80, 91, 128, 145), forty-five feet 
(137), between forty and fifty feet (115, 147), fifty feet at least 
(43, 46, 50, 51, 60), about fifty-five feet (94), from fifty to sixty 
feet (63), sixty feet (57, 83, 117, 118, 129, 138, 150), seventy- 
five feet (152 a), eighty feet at least (97), a hundred and fifty feet 
(154), and, though estimated by the eye-witnesses at about fifty 
feet, the visible part must, according to my reckoning, have been 
eighty feet at least in n°. 148. These enormous differences in the 
statements cannot surprise us of an animal which may attain a 
length of more than two hundred feet. As a rule the animal swims 
with head and neck above the water-surface, commonly the back 
too is partly visible, but of the tail only a small portion. In 
n°. 154 as we see, a length of 150 feet of the animal was visible; 
in this instance it lay nearly perfectly still; only the long neck 
and head were under water, and the back and a great length of 
tail were above the surface. 
The whole length of the animal is spoken of as: great (87, 152), 
large (119), very large (2), considerable (107), immense (86), as- 
tonishing (1), enormous (182), as a yacht of fifty tons (8), three 
or four times larger than the ship (5), eighteen feet (14), from 
fifty to fifty-five feet (19), from fifty to sixty feet (18), sixty feet 
(17, 28, 56), at least sixty feet (82), more than sixty feetm2o) 
from sixty to seventy feet (24), from sixty to eighty feet (139, 142), 
about seventy feet (29), not above seventy feet (109), at least 
seventy feet (41), from seventy to eighty feet (31), from seventy 
to one hundred feet (74), seventy five feet (1, 158), about eighty 
feet (63), from eighty to ninety feet (39, 118), about ninety feet 
(121, 134), one hundred feet (17, 33, 41, 44, 45, 63, 66, 69, 135),
