There remain for consideration the terms used to designate the 

 following internodia; in the armus, the carpus, the metacarpus, and 

 the phalanges', in the slcelos, the tarsus, the metatarsus, and the pha- 

 langes; also the nodi which separate them and which are called carpo- 

 metacarpal, metacarpophalangeal (or knuckle) and inter-phalangeal 

 articulations of the armus, and tarso-metatarsal, metatarso-phalan- 

 geal and inter-phalangeal articulations of the skelos; there are obvi- 

 ous objections to all these terms, chiefly on the score of length, and 

 the shorter terms of Hippotomy (cannon-bone, great and little pas- 

 tern, and coffin-bone, etc.), are not available for our purpose. I am not 

 prepared to suggest the technical terms which are needed, excepting 

 in the case of the phalanges or digital and dactylic internodes. 

 These are variously termed proximal, middle and distal, or first, sec- 

 ond and third (proximal phalanx of the index, etc.), but all these 

 terms are objectionable as to length, and the latter in that they do 

 not indicate whether first is counted from the proximal or the distal 

 extremity of the digit or dactyl. I would therefore suggest that the 

 terminal phalanx of a digit or dactyl be called a (alpha), the middle 

 one, p (beta), and the proximal, y (gamma) ; the corresponding meta- 

 carpal bone may be called delta (^). 1 For the present, however, 

 the above nomenclature should be employed only when there are three 

 phalanges in the digit or dactyl; for when the number is less, we are 

 not yet sure which is the missing one; 2 and when there are more, 

 as with Cetacea, the homologous phalanges are undetermined. 



To show what a reduction of labor and space is gained together 

 with the greater definiteness, instead of saying that the Extensor 

 indicis (of man) is inserted into the third phalanx of the fore-finger, 

 we may now say that it is inserted into "« indicis." 



There seems to be an ideal, if not a real, difference between the 

 above mentioned segments of the manus and pes and those three pri- 

 mary segments which have been generally recognized ; the same may be 

 said of the articulations between these segments. And although upon 

 strict anatomical grounds we must designate them also as "internodia" 



1 This is less complex and artificial than the nomenclature of the metacarpals 

 and metatarsals proposed by Strauss-Durckheim, 331, 1, 116 and 124. 



2 This problem will be discussed hereafter.
