Hochstetter. Ueber die Nichtexistenz der sogenannten Bogeiifurchen an den 



Gehirnen lebensfrisch konservierter menschlicher Embiyonen. 27-34. 

 Schaper, A. Zur Frage der Existenzberechtigung der Bogeiifurchen am 

 Gehirue menschlicher Embryonen. 35-37- 

 Both of these papers on the embryonic fissures agree with the re- 

 cent work of Retzius, Mall and Goldstein, who find no true 

 fissures in the wsU preserved human brain during the period to which 

 His assigned his "Bogenfurche." 



Ramstrom. Ueber die Innervation des Peritonaeums der vorderen Bauchwand. 

 This study was made upon I'n^ra vitam methylene bhie impregna- 

 tions of the psritoneum and associated tissues. In the mouse, the perito- 

 neum on one side the median line was ludunted entire. No fibers from 

 the i)hrenic were found entering this region. The innervation is wholly 

 from the intercostal nerves, through a complicated system of plexuses. 



Lubosch, W. Uber den Bau und die Entwickelung des Geruchsorganes von 

 Petromyzon. 67-75. 



This paper bears upon Blaue's theory of the origin of the olfactory 

 epithelium by a process of fusion of primitive cutaneous sense organs. 

 The author conceives the olfactory buds of Petromyzon as represent- 

 ing a protracted ontogenetic process. The fuiidament of the olfactory 

 organ is in the form of a bud-like differentiation of the integument. 

 The organ develops by a repetition of this process. Lubosch considers 

 that Blaue's theory may be tenable upon the hypothesis that in the 

 olfactory organ the nerve cell has maintained the primitive position, 

 which it originally held in both olfactory and taste organs. Perfectly 

 closed follicles are found in the nasal cavity of ten-centimeter larvae.

 Rutter, Cloudsley. Natural History of the Quinnat Salmon. Bull. U. S. 

 Fish Commission for 1902, 65-142. 9 Pis., 13 Figs. 1904. 

 The objects of this investigation were to determine when young 

 salmon should be liberated from the hatcheries, to discover a method 

 for removing and fertilizing the eggs left in the fish after artificial 

 spawning, and to fix the site for a new hatchery. Other matters of 

 interest discussed are the activity of spermatozoa after the milt is mixed 

 with water, the fertilization of the ova, care in handling embryos, 

 alevins and their enemies, the fry and their food, parasites, and migra- 

 tions, the food of young salmon and their period of growth. The adult 

 salmon are treated in relation to migrations, changes after entering fresh 

 water, sexual differentation, natural propogation, injuries and diseases, 

 and death which ensues after once spawning. This contribution is of 

 considerable scientific importance as well as being of practical value.
