species, and which could not exist near the surface, owing to the dis- 
tention and rupture of their air-bladder when removed from the 
pressure of deep water. 
“Mr. Grosse mentions that the ship in which he made the voyage 
to Jamaica was surrounded in the North Atlantic, for seventeen con- 
tinuous hours, by a troop of whales of large size, of an undescribed 
species, which on no other occasion has fallen under scientific observa- 
tion. Unique specimens of other Cetaceans are also recorded. 
“We have evidence, to which attention has been directed by Mr. 
A. D. Bartlett, that ‘ even on land there exists at least one of the 
largest mammals, probably in thousands, of which only one individual 
has been brought to notice, namely, the hairy-eared, two-horned 
rhinoceros {R. Lasiotis), now in the Zoological Cardens, London. It 
was captured in 1868, at Chittagong, in India, where for years 
collectors and naturalists have worked and published lists of the 
animals met with, and yet no knowledge of this great beast was ever 
before obtained, nor is there any portion of one in any museum. It 
remains unique.’ 
“I have arrived at the following conclusions: 1. That without 
straining resemblances, or casting a doubt upon narratives not proved 
to be erroneous, the various appearances of the supposed ‘great sea- 
serpent ’ may now be nearly all accounted for by the forms and habits 
of known animals ; especially if we admit, as proposed by Dr. Andrew 
Wilson, that some of them, including the marine snakes, may, like the 
cuttles, attain to extraordinary size. 2. That to assume that naturalists 
have perfect cognizance of every existing marine animal of large size, 
would be quite unwarrantable. It appears to me more than probable 
that many marine animals, unknown to science, and some of them of 
gigantic size, may have their ordinary habitat in the sea, and only 
occasionally come to the surface ; and I think it not impossible that 
amongst them may be marine snakes of greater dimensions than we 
are aware of, and even a creature having close affinities with the old 
sea=reptiles whose fossil skeletons tell of their magnitude and abundance 
in past ages. 
“ It is most desirable that every supposed appearance of ‘ the G-reat 
Sea-Serpent ’ shall be faithfully noted and described ; and I hope that 
no truthful observer will be deterred from reporting such an occurrence 
by fear of the disbelief of naturalists or the ridicule of witlings.”
