1828. RosANOFF, Aaron J. A theory of personality based mainly on psychiatric experi- 

 ence. Psychol. Bull. 17: 281-299. Sept., 1920.— The author maintains that his evidence shows 

 the four defined abnormal types of personality known as the antisocial, cyclothymic, autistic, 

 and epileptic, bear to one another in their blending, relationships analogous to those of coat 

 colors in mice. The most striking feature these varieties of neuropathic constitution have in 

 common is their behavior as Mendelian recessives in relation to normal constitution, the 

 degree of inhibition of manifestation constituting, however, a homogeneous group of Men- 

 delian units. Therefore Bateson's terms epistatic and hypostatic are preferable to domi- 

 nant and recessive. — 'Manic-depressive parents often have schizophrenic offspring, rarely 

 the reverse, suggesting an epistatic position for them, but epilepsy apparently occupies a 

 hypostatic position not only in relation to the normal but to all constitutional psychoses.— 

 Mixed conditions are combinations of traits occupying contiguous positions in the scale of 

 dominance. Epileptic phenomena are more often seen in dementia praecox (autistic type) 

 than in manic-depression (cyclothymic type), and autistic phenomena more often in manic- 

 depression than in psychoneurotic (antisocial) cases. So also rudimentary psychoneurotic 

 symptoms are more often seen in normal individuals than are the other kinds of phenomena. 

 The facts of ontogeny seem to show that latent neuropathic elements of personality are, in 

 various combinations and degrees, regular components of so-called normal personality and 

 are particularly susceptible to release through the action of alcohol.^The psychological test 

 data from the author's patients at Kings Park State Hospital show that any degree of intel- 

 lectual capacity may be transmitted to either of the types of make-up, but the relative fre- 

 quency of feeble-mindedness seems to increase with descent in the scale of dominance, pre- 

 sumably due to the loss of epistatic factors which are not always made up quantitatively 

 by hypostatic ones.— Nomadism is correlated with the antisocial, autistic, and epileptic 

 constitutions. Handsome physical features are particularly correlated with the cyclothymic 

 type.— Concerning sex-linked traits of personality the author speaks of criminality, drug 

 addiction and autistic psychoses as more frequent in men, while hysteria and cyclothymic 

 tendencies appear more prevalent in women. ^il/iriam C. Gould.

1830. Saunders, Edith R. Multiple allelomorphs and limiting factors in inheritance in the 

 stock (Matthiola incana). Jour. Genetics 10: 149-178. 2 pL, S fig. Aug., 1920.— Results 

 indicate a case of multiple allelomorphism involving the genes H (hoary). Hi (half-hoary), 

 and h (glabrous). The data are as follows for the locus or loci under consideration. Among 

 319 plants in F2 from hoary X half-hoary none were glabrous (and none of a fourth class pos- 

 sible if hoary and half-hoary were not allelomorphic). Crosses involving hoary-half-hoary 

 heterozygotes by half-hoary-glabrous heterozygotes gave 134 plants, none glabrous. Crosses 

 involving heterozygotes for hoary-half-hoary by homozygous half-hoary gave two classes of 

 plants, 37 of one (hoary) and 45 of the other (mid-hoary). Crosses involving heterozygotes
