By rnrofully dissecting out the Lumhricales, they may 

 be foiiiid, each pair with an origin on the under side at 

 the point of bifurcation of the tendons, to tlie a[)propriate 

 dii>its. Their size is uniform. 



Mm. Interossei. 



Tlie results of my dissection of these muscles differ 

 from those obtained by Mivart. Two small muscles arise 

 from the thick tendon of the Flexor (^aipi Radialis, and 

 pass to each side of the distal [)hahinx of the i)oIlex. They 

 arc inserted by small tendons ; one on the radial and the 

 other on the ojjposite side of the piialanx. Two nmscles 

 very nuich re.somblin<i: these, but larirer, arise from the 

 base of the metacar[)al bone of the index, and are inserted 

 in a similar manner to the former, into the distal phalanx of 

 the index. These insertions are also by small tendons on 

 the radial, and o[)p()site surl'ace of tlio index. Another 

 pair, ditfcrins; trom the precedin<^, by being more widely 

 separated, and not at all coimected at the base, as in the 

 case of those of the index and pollex, arise from below the 

 OS magnum, and have an insertion into the distal phalanx 

 of the thiid digit. A small inteiosseojis nuiscic arises 

 ou the radial side of a sti-ong tendon, passing obliquely 

 across tlu; palmer region of the manns. It is inserted 

 into tiie radial surface of the distal phalanx, of the fourth 

 diuit. The obliipie tendon, near which, this interosseous 

 muscle lies, is a conlinuatiiui of the Flexor Carpi Ulnaris. 



INIivart mentions another interosseous muscle of the 

 fourth digit which I have been unai)le to make out. As 

 it lies tlircctly under the pair of Lmnltricalcs, which he 

 missed in his disst'clion, or at lea.>>t has not desciabed, I 

 suiigest that he mi>took a Lnml)ricalis, for an Interosseous 

 muscle. Situated superficially to the great tendon (jf the
