devient line jeune Conjuguee, qui etoit toute entiero contenue dans le vieux 

 tube, com me die meine contient les plantes qui doivent fe devellopper enfuite : 

 elle en forr par l'extreraite lorfqu'elle occupe la derniere loge, ou par les cotes 

 lorfqu'elle fe trouve dans une des loges du milieu." 1 have fometimes feen the 

 fimple filaments of C. ger.i/Jlexa rolled round in a Terpentine form, as Mullcr has 

 reprefented, and thefe have been erroneoufly referred by M. Vaucher to a 

 feparate fpscies. 



Each joint of the Conjugate puts forth only one connecting tube, which is 

 fometimes on one fide of the filament and fometimes on the other ; fo that each 

 filament is often connected with t.vo others. A fhort time after the union has 

 been effected, the granules from one joint, gradually pafs into that with which 

 ic is joined, till the former at length becomes empty and colorlefs. The granules 

 of both then coalefce in the other joint, or in the connecting tube, and form a 

 globular or oblong mafs, wh ch M. Vaucher has proved to be the true feed, 

 and has feen it germinate and reproduce the fpecies. No feeds appear to be 

 ever formed but by this union of the joints of two different filaments with each 

 other, and of thefe united joints only one ever produces a feed. It is therefore 

 natural to conclude, although the contents of the joints by their appearance 

 cannot in the leaft be diftinguifhed from each other, and although in things fo 

 minute and obfcure it is neceffary to fpeak with the utmoft diffidence, that one 

 contains male and the other female powers, and that their union is effeiltial to 

 the propagation of the Conjugate. It might indeed reafonably have been fup- 

 pofed that of two conjugated filaments, the whole of the one is male and the 

 other female, but in oppolition to this it generally happens that a part of the 

 joints give out, and a part receive granules in the fame filament. I have feen 

 three filaments connected together, and the connecting tubes of the middle 

 one have fometimes been thrown out by the joints on one fide, and fometimes 

 on the other, and the feeds have been formed in either filament, without ap- 

 parent order. Each filament muft therefore be confidered hermaphrodite, pof- 

 feffing in its different joints both male and female powers, which, as in the
