mouse, and branched ends in the cat, p. 62, (Sec. 7); states that 

 intramuscular endings are always applied to fibers of full size, p, 

 92, (Sec. 11); calls attention to the necessity of measuring fibers at 

 their full size, p. 63, (Sec. 5) ; figures cardiac muscle from the great 

 groups of vertebrates, pp. 66-71; thinks a stimulus might be 

 transmitted from one lapping fiber to another, p. 72. (See conclu- 

 sions). 



13. Haller. — Elementa physiologise. 1757-1766. Says some 

 fibers have fine, acute ends. Vol. IV, Sec. 1, p. 3; hence Krause 

 gives him the credit of discovering intramuscular ends. 



14. Hay craft, J. B. — Upon the cause of striation of volun- 

 tary muscular tissue. Quart. J. Micr. Sc. 1881, pp. 307-329, 

 illustrated Thinks the fiber is structureless, the cross-markings 

 being due to its beaded form, with perhaps the exception of Dobie's 

 (Krause's) line, which occurs at the narrow part (Sec. 13), and 

 shows the different appearances due to change of focus of the 

 microscope, pp. 315, 327. (See Fig. 52). 



15. Heitzmann, C. — Microscopical morphology of the animal 

 body, pp. 849. Illustrated. New York, 1883. Says the sarcolem- 

 ma is a structureless, corrugated membrane, without nuclei, passing 

 around the end of the muscular fiber, which is joined to the tendon 

 connective tissue, p 267. (Sec. 13.)

 ter Muskelfasern, Sitzungsb. d. k. Akad. d. Wissench. Math naturw. 

 CI. Wien, Bd. XXX, 1858, pp. 73-74. First found spindle-form 

 fibers in muscles of the cow and sheep. (Sec. 3.)

 musculaires striees chez les invertebres. Compt.-rend. Acad. d. Sc. 

 Par. T. XCV, 1882, p. 1003-4. Find fibers anastomose in the 

 digestive tube of larval insects and the gastric appendages of 

 Crustacea, where they tend to produce simultaneous movement. 

 (Sec. 12 and conclusions.) 



18. Kolliker, A. — Handbuch der Gewebelehre des Menschen, 

 pp. 749. Illustrated. Leipzig, 1867. In the middle of the longer 

 muscles the fibers are spindle- form, and at the ends are tapering, p. 

 159. (Sees. 1-3 and 11.) Thinks fully formed fibers may divide 

 into two or more by longitudinal clefts, p. 178. (Sec. 10.) In 

 developing muscle, nuclei occur in rows and groups, p. 176.
