BALiEMID^. 



There is also tlie skeleton of the same foetus, prepared by Mr. Knox. 

 The bones of the head are ossified, and show the characters of the 

 genus ; that is, the upper jaw is high, arched, and its sides are only 

 slightly keeled, not depressed and expanded as in Balanoptera, &c. 

 The jaws show the grooves for the teeth. The rest of the skeleton 

 is only cartilaginous. These specimens are descifibed by Mr. Knox, 

 Cat. Anat. Prep. Whale, 21. 



There is the skeleton of a half-grown specimen, brought home by 

 M. Guerin, in the Anat. Mus. Univ. Edinb. (head 6 feet long?). 



Mr. Knox gives some observations on the lactiferous glands of a 

 foetal specimen in the account of the dissection of a Balama rostrata. 

 The foetus is also described by Eoussel de Vauzeme, Ann. Soi. Nat. 

 Zool. 1834, ii. 125; L'Institut, 1833, i. 106, and 1834, ii. 289; 

 Wyman, Proc. Boston Soc. N. H. 1850, iii. 356 (foetus). 



The embryo of a whale in spirit was presented to the Nat. Hist. 

 Soc. of Newcastle-upon-Tyne, in 1836, by J. Stevens, Esq. 



A foetal specimen is figured by Camper (Cetac. 1. 1. f. 1, 2). It is 

 probably from a dried specimen, and the head is very slender. It is 

 to be observed that it is longer in proportion to the length of the body 

 than the very young specimen of B. australis, 17 feet long, figured 

 by Delalande, Diet. Class. H. N. 1. 140. f. 3. 



The Icelanders distinguish two kinds of Whale, that of the North 

 (Nord Hvale) and that of the South, They say that the skia of the 

 latter has white calcareous crowns (CoromMJoe) which are not found in 

 the former. (See Van Beneden, Bull. Sci. Belg. 1860, xxii. 460.) 



Each species of Whale has its own peculiar kind of sessile Cirri- 

 pede ; one has the Goronula, another the Biadema, and a third the 

 Tubidnella. They are all sunk in the surface of the skin, with the 

 aperture for the free valve, or operculum as it is called, alone ex- 

 posed, and as they grow in size the deeper they sink into the skin. 

 Some genera aUied to Goronulce are found on the shells of turtles, 

 and on the outer surface of shells that are partially covered by the 

 mantle of the animal. The Whales have also pedunculated Cirri- 

 pedes, as Otions, on them : these were early observed. " This Whale 

 hath naturally growing upon his backe white things like unto Bar- 

 nacles " (Purchas, PUgrims, 471). Goronula Balcenaris is found on 

 the Eight Whale of the Arctic Seas (see Pontoppidan, §§ 78, 81). 



Some observations on the osteology are given by Professor Owen 

 in Cat. Osteol. Mus. Coll. Surg. ii. 439 & 441. 



Professors D. F. Eschricht and J. Eeinhardt, in " Om Nordhvalen, 

 Balcma Mysticetus," published separately in Copenhagen in 1861, and 

 in the fifth volume of the Transactions of the Danish Eoyal Academy, 

 have given a very full account of the osteology of this animal and 

 its allies in the North Sea. 



The male and female " Baleine franche," figured by Duhamel, 

 Peches, ii. 1. 1. f. 1, 2, and which are copied in the 8vo edition of 

 Bloch, Fische, 1. 1, seem like figures made from description by an 

 artist who had the figure of a Dolphin, or rather Grampus, in his 

 eye. The baleen is drawn as if it was attached to the lower jaw, 

 and projects from the mouth in front. The same figure, with a series
