around, above, and below an artery, freely branching, 

 bifurcating, and supplying all the neighboring forma- 

 tions with a large number of delicate fibrillae. . . . 

 The bundles of nerve-fibres give off dolicate ramules 

 to the afferent vessels by which they enter the tuft; 

 and here they produce a delicate plexus spun around 

 its capillaries. It was impossible to decide where the 

 ultimate fibrillae branch in the capillaries of the tuft. 

 . . . Sometimes I obtained specimens in which it 

 seemed as if the ultimate fibrillae branched beneath 

 the covering, flat epithelia in the delicate connective 

 tissue between the convolutions of the capillaries.

 new raicroscope-stand with concentric movements, 

 by J. D. Co.x; new modification of the Spitzka micro- 

 tome, by V. S. Clevinger; and a new binocular 

 arrangement, by Edward Bausch.

satisfying one's self of the fact that every tubule is 

 encircled by a plexus of non-meduUated nerve-fibres, 

 coursing either in the immediate vicinity of the tu- 

 bule, in the interstitial connective tissue, or within 

 the dense layer subjacent to the epithelia, known 

 as the memhrana propria, or even with the layer 

 along the feet of the epithelia themselves."'

THE JAVA UPHEAVAL.^ 



TuE details which have reached us during the past 

 week, of the terrible seismical manifestation at Java, 

 prove it to be one of the most disastrous on record. 

 Probably, moreover, it is the greatest phenomenon 

 in physical geogr.aphy which has occurred during at 

 least the historical i)eriod, in the same space of time. 

 The accompanying sketch-map will afford some idea 

 ■ of the extent and nature of the change which has 

 taken place, and the character of the sea-bed and the 

 land in the region affected.
