DEVELOPMENT OF THE OVA. S75 



the scissors, causing the escape of the ova. Such as 

 were quite loose gave indication of heing cihated, in 

 that they had a feeble spontaneous motion, a quiver- 

 ing oscillation. 



A week afterwards (October 2nd) I again examined 

 the ovaries : the one that most protruded was more 

 opaque, of a creamy hue. With a lens I perceived 

 that the free ends of many of the tubes were project- 

 ing, and hanging down like a short fringe of threads, 

 with blunt tips. I again cut off and isolated a por- 

 tion in a watch-glass. The appearance was much 

 changed since I examined it last. The tubes, which 

 had the same vermicular motion as before, and were 

 similarly convoluted, were greatly swollen in irregular 

 parts, and contained many ova much more developed 

 than before. These were clear globules, yet evidently 

 granular, varying from ^^ to ^ inch in diameter. I 

 soon found that they were escaping from the ovarian 

 tubes, (not however, from the free ends, which were 

 slender and contained no ova) ; and after the severed 

 fragment had remained a night in the watch-glass a 

 great number, of varying sizes, were found on the 

 bottom, moving about. 



Some of these I examined with a power of 300 

 diameters, Each was a soft globose body, not quite 

 regular, nor even fixed in form, of a clear brownish 

 hue, composed of a great number of irregular granules 

 aggregated together, which projected from the gene- 

 ral outline ; as if a handful of roundish pebbles from 

 the shore had been agglutinated by some invisible 

 cement into as good a ball as you could make of such 

 materials. The globule revolved in all directions on its
