 Zweite Auflage. 

 Although intended primarily for those who have professional in- 

 terest in juristic ]jroblenis and in the scientific side of criminology, this 

 hook of Geoss' contains much that is of value to the comparative psy- 

 chologist. In reading it one is likely to be impressed with the obvi- 

 ous need of psychological knowledge in the treatment of criminals and 

 defectives. But, at the same time there is opened up, in thoroughly 

 scientific systematic fashion, a vast realm of abnormal psychology which 

 has been almost entirely neglected by scientific investigators, namely, 

 the psychology of crime. The work is authoritative, and in this sec- 

 ond edition it has been considerably improved iu form and increased 

 in value. R. m. y. 



Streeter, George L, The Development of the Cranial and Spinal Nerves in 

 the Occipital Region of the Human Embryo. Am. Jour. Anat., 4-, 

 83-116. 1904. 

 A study of numerous human embryos from the collections of 

 Hrrtwig, Mall, His and Golci. The period, 20-81 days, involves 

 all the changes in form and relation from the time when the peripheral 

 nerves are first ca])able of reconstruction to the time when the adult 

 condition is practically established. The ganglionic crest in the cere- 

 bral region is from the first distinct from the trunk ganglia, though it is 

 connected with the latter by a thin sheet of loosely arranged cells. 

 The ganglia petrosum and nodosum are apparently adherent to thick- 

 ened patches of the epidermis. The ganglionic crest of the tenth and 

 eleventh nerves at first shows no signs of segmental arrangement. The 

 latter nerves are found to belong to the same complex and alike have 

 root ganglia and motor and sensory roots. In the course of develop- 

 ment the sensory element comes to predominate in the cephalic por- 

 tion of the complex and the motor in the caudal portion. The hypo- 

 glossal is like the ventral cervical roots in position and segmental ar- 

 rangement. The ventral spinal nerves are developed earlier than the 

 dorsal roots. g. E c.

 1904. 



In the ventral nerve cord of Scohpcndra the conduction rate is 

 greater in the antero-posterior direction. This antero-posterior differ- 

 entiation, is most marked in the short types. Experimental studies on 

 the localization of centres of control of important reflex functions.
