Professor John Wood's papers in the Philosophical Transactions for 1869 on 

 the Varieties of the Human Shoulder Muscles and their homologies in the 

 Mammalia should be read in connection with the above description of those muscles 

 . in the Rabbit. Many other memoirs on Myology in its various aspects, morpho- 

 logical and physiological, have appeared in this country from the pens of Professors 

 Turner, Haughton, Macalister, Mivart, and Drs. Murie, J. D. Cunningham, A. H. 

 Young, and others in the Proceedings of the Zoological Society, the Journal of 

 Anatomy and Physiology, and elsewhere; and abroad from those of Professors 

 Gruber, Gegenbaur, Fiirbringer, Riidinger, and MM. J. C. G. Llicae and Paul 

 Albrecht. The muscles of the Rabbit are treated of in Professor Krause's mono- 

 graph, Die Anatomic des Kaninchens, pp. 136-138, ed. 2, 1884, and those of the 

 other domestic animals in Chauveau, Traitd d' Anatomic Compare'e des Animaux 

 domestiques, 2 nde eM ; 1871, pp. 200-347, Franck. Anatomic der Hausthiere, 1871, 

 pp. 343-478 ; Gurlt's Handbuch der Vergleichenden Anatomic der Haussaugethiere, 

 ed. Leisering and Mtiller, ed. 5, 1873, pp. 206-329. For the masseter muscle 

 in Rodents and its relation to the antorbital fissure, see Waterhouse, History 

 of Mammalia, ii. p. 151, PI. 6 a, 1848; Brandt, Mem. Acad. Imp. Sci. St. Pe'ters- 

 bourg, Se"r. 6, Sc. Nat. Tom. vii. 1855, p. 153 ; Giebel, Zeitschrift, Ges. Wiss. 1865, 

 p. 427; A. Milne Edwards, Nouv. Archiv. Museum, iii. p. 92, 1867, Lophiomys; 

 and Cuvier, Leons, ed. 2, 1835, iv. pt. i, p. 67, where the maxillary portion of 

 the masseter is called ' musculus mandibulo-maxillaris.' 



6. DUODENUM, PANCREAS, SPLEEN, AND LEFT KIDNEY, TOGETHER 

 WITH PORTIONS OF STOMACH, OF THE JEJUNUM, OF THE LARGE 

 INTESTINE, AND OF THE MESENTERY OF RABBIT (Lepus cuni- 



CuhlS) IN THEIR MUTUAL RELATIONS. 



With Figure 2. 



THE stomach, which in these animals, like the paunch of Ruminants, 

 is never found empty after they begin to eat solid food, has been removed, 

 with the exception of a little more than an inch of its pyloric end, a. As- in 

 nearly all Vertebrata, with the exception of the Ophidians, the terminal 

 segment of the digestive tract, h to k, comes into close juxtaposition with 

 this portion of the stomach and the duodenum 1 . As noteworthy points 



1 See Cuvier, Lefons d'Anatomie Comparee, ed. 2, 1835, torn. iv. pt. 2, p. 657: 'Dans toutes 

 les classes des vertebres, 1'ordre des ophidiens seul excepte, le canal alimentaire a toujours une 

 portion qui repond au gros intestin plus ou moins rapprochee de 1'estomac ou du commencement du 

 canal intestinal.' And compare the plates in Rathke's memoir, Ueber den Darmkanal des Fische, 

 1824, which show that this arrangement exists in most orders of Fishes as well as in air-breathing 

 Vertebrata.
