in the AMDRUP collection. I do not know whether he bases this comparison 
on personal acquaintance with JocHELSON’s dolls; if so, then they are 
not made with movable joints, for the bear in question has no movable 
joints, its legs being merely pegged into their sockets (vide THazs. I, 
p. 534, Fig. 105). 
SHARK’S TOOTH KNIVES AND UMIAK CLEANERS. 
With regard to the strange knives edged with shark’s teeth, Mr. 
THALBITZER observes!: “Shark’s tooth knives (Fig. 187) for cutting hair 
have been mentioned? on р. 32. Such knives seem also to have been 
known in West Greenland in earlier times, for OLEARIUS mentions, that 
his Greenlanders had some knives, which they called ekalugsaa, that is 
they explained with this word, that the knives were made from sharks 
(presumably the teeth of sharks) 6). The teeth are inserted into grooves 
along both edges, like the small iron blades in the primitive knives we 
know from northern West Greenland and Southampton Island (see 
р. 489)”. Note 6 runs as follows: “OLEARIUS (1656), р. 174. Illustration 
from southern East Greenland by Graan (1832) PI. УП”. 
Glancing first at Fig. 187, we here find two knives shown, and stated 
by the Author as belonging to the Horn collection. This is true, however, 
only as regards 187a, that marked b. being as a matter of fact the very 
one brought home by GRAAH and mentioned by Mr. THALBITZER in 
Note 6 as from southern East Greenland (to be precise, from Malingisek, 
Lat. 62°20’ N.); it should be noted, however, that the knife will be found 
shown in GRAAH's book, not in Pl. VII, but in PI. VIII. 
The reference to OLEARIUS is, like Mr. THALBITZER’s earlier quotation 
of the same author’, not altogether correct. OLEARIUS says, in the 
passage in question, “Ihre Messer seind von Backen Zåhnen eines Meer- 
fisches, welchen sie Ekulugsua, Piso aber in historia naturali Brasiliæ 
p. 180 und Jonstonius de piscib. p. 201 Piratia Pua auf Brasilianisch 
nennen’. 
The form “welchen’” must necessarily refer to “Meerfisch” and not, 
as Mr. THALBITZER’s seems to have read, to “Ihre Messer”. Properly 
construed, the words of OLEARIUS tell us, clearly and distinctly enough, 
that it is the fish, not the knife, which the Greenlanders called Ekulugsua. 
He writes the work ekulugsua, not, as Mr. THALBITZER spells it, ekalugsaa, 
and intends thereby to give the native name for the Greenland Shark 
(ekalugssuak). Nor is it easy to understand why the Editor, if he had 
read the passage in OLEARIUS, should find it necessary to advance the
