the deep flexor is an anomaly and in no way to be associated with 

 the typical form of the muscle in either limb. I have found it 

 but once, and have figured it as suggestive of the genetic relation- 

 ship of the two muscles. 



Mm. flexores breves profundi (fbp). These four little 

 digital slips are iii all particulars precisely as in the hand, to the 

 description of which, as well as to Figs. 30 and 31, the reader may 

 be referred The little cross slip, shown in Fig. 31, is not a con- 

 stant feature but an anomalous one, and was included merely be- 

 cause the drawing was made from a camera sketch and represents 

 an actual dissection. Whether there is any morphological significance 

 in this or in other similar variations, I cannot say. 



M. flexoT interphalangeus digiti quarti (fi). This 

 minute slip is the same in both nembers. The Separation of the 

 muscle into two bundles, as figured in Fig. 37, is not usually as 

 well-marked. The connection between this muscle and the deep 

 flexor has been already commented upon (sub fbs in the foot and 

 fi in the hand). 



Mm. tarsometat arsales (b, cd, ef,gh, those of the from 

 digits respectively). These muscles correspond closely to the car- 

 pometacarpales of the hand, differing from them in only a few 

 details : 



Digit IL The outer (fibular) slip is more extensive, and spreads 

 out to a longer line of insertion. 



Digits III and IV. The two associated slips belonging to each 

 digit are a little better developed than in the hand and are often 

 confluent across the middle line of the digit, so that they may 

 appear like a single sheet until they near their insertion. 



Digit V. The outer (fibular) slip arises from the distal outer 

 corner of the fibulare-intermedium ; an origin from the tendon of a 

 fibular flexor, as in the hand, is here impossible, owing to the 

 reduced condition of this muscle. 



Mm. intermetatarsales (im 1 — 3). These small muscular 

 sheets, which Stretch across the three interosseous spaces, corre- 

 spond exactly to those in the hand. They arise from the tibial, 

 and insert into the fibular margins of the metatarsals. 



M. interosseus (io). This muscle is in the form of an oblique 

 band, crossing the interspace between fibula and tibia and, strictly 

 speaking located neither upon the extensor or the flexor side, but
