Mr. Griffith on the Ovulum q/"Santalum album. 67 



of the tube is visible from the ruptured apex, of which molecules are 

 escaping. To the dilated apex of the tube two filaments and some 

 remains of cellular tissue are seen to adhere ; cells are likewise seen 

 adhering to the margins of the upper half of the tube. The vesicle 

 is visible within the dilated apex, and appears to be continuous with 

 the grumous process. At its base 4 globules are seen. The upper 

 half of the grumous process is very distinct ; below this, however, it 

 is broken up. The commencement of the development of the basilar 

 inner cell is distinct, but its intrusion has not yet taken place. 



Fig. 9. Represents the dilated exserted part of the membranous tube of an ovu- 

 lum, from an ovarium 2^ lines in length. This is torn partially, so as 

 to expose what appears to be a large cell with very fine walls. Within 

 this the innermost small cellule is visible, and appears filled with 

 grumous matter. The faint line visible at its base, and which appears 

 continuous with the second fine cell, marks its line of origin. The 

 constricted, or rather, narrow exserted portion, is occupied also by 

 molecules in a state of aggregation. The apex of the nucleus re- 

 mains. 



I may here remark that I am by no means certain of the existence 

 of the fine large cell above mentioned. The innermost small cellule 

 exists, I may almost say, invariably. 



Fig. 10. Represents an ovulum from an ovarium 2^ lines in length. The apex 

 of the ovulum alone remains. The base of the membranous tube is 

 much enlarged, and has evidently become cellular. At the same 

 time there is much less granular matter (molecules) observable in 

 its tissue. This cellular part appears to be prolonged upwards in the 

 form of 2 or 3 cells, a, a, a. Between this part and the apex there 

 is much grumous matter, composed almost entirely of small granules, 

 and which presents traces of subdivision, the tendency to subdivision 

 being most distinct at the apex. Adhering to the margins of the 

 tube towards its apex, remains of the cellular tissue of the placenta 

 are visible. The vesicle is very distinctly seen within the apex, the 

 extreme part of which appears sphacelated. To it a filament is 

 seen adhering.
