102 MICROSCOPICAL STUDIES. 



have are exactly of the same appaaranca as those that appeared three 

 years ago, save that they have spread and multiplied exceedingly 

 Excepting accidents they are likely to exist as long as they receive 

 the moderate attention they have had so far. I do not, however, 

 mean to assert that the same individuals are now alive as in the 

 baginning, though it is probable they may live two or more seasons. 

 The chapter of accidents is long and those living to-day are in most 

 cases, at least, the budded off and replace successors of the original 

 ones. 



On PI. VI., figs. A. to D., are drawn a group of four as seen when 

 in active budding on Christmas Day, 1894. They were attached to 

 the side of a bell jar in a most favourable position for observation- 

 Fig. A a shows side view of one of these to show how in some 

 cases the stolon has been given off from the polyp body at a point 

 considerably above the attachment disc ; thus the stolon bends down 

 to root at a distance from the parent, after the fashion of the branches 

 of the banyan and the mangrove. In others it emerges low down as 

 at fig. C*. 



EXPLANATION OF PL. VI. FIGS. A TO C. 



Fig. A, B, C & D. A group of Scyphistomata of Aurelia aurita, 

 drawn on Christmas day, 1894, when attached to the 

 side of a bell jar. d is the adhesion disc, b a prolife- 

 rated bud ; B shows in the best manner, the development 

 of a stolon. A" and C a are profile views of A and C 

 respectively.
