 ings seen in the belt are compared with those observed in 1911 in 

 the tropical and sub-tropical regions of the southern hemisphere 

 of Jupiter. A general discussion of these proper motions.

Tne Effect of a S03) Bean Crop on a Follo\\'ing Cereal 



By Maurice Mulvania, University of Tennessee. 



(Abstract.) 



1. A mature crop of soy beans injures a following cereal. 2. 

 The growth does not seem to decrease the soil nitrogen. 3. 

 Beans cut for hay do not produce the inimical effect. 4. The 

 experiments did not indicate the presence of a toxin. 5. The sys- 

 tem, soil, beans and nodules, shows a gain in nitrogen up to the 

 hay stage of the beans. 6. The bacteria of the soy bean nodules 

 probably never form distinct branching. 



Tne Fourtn Dimension 



])y Samuel M. Barton, University of the South. 



(Abstract.) 



Jn this ])a])er the author gives a non-mathematical exposition 

 of h_\'])cr-s])ace. The aim of the paper is to make clear to the 

 "layman" what is meant by the fourth dimension or space of any 

 dimension higher than three. To this end the subject was of 

 necessity treated in an elementary manner and at considerable 

 length. In ])articular it is slK)wn that while our experience 

 teaches us nothing of space other than that of three dimensions, 

 the conception of hyper-space is perfectly reasonable. The na- 

 ture of the ])a])er ])rccludes giving an abstract of it.
