468 Meteorological Observations. 



My friend Mr. Bowerbank examined this Mould with the micro- 

 scope. When highly magnified, many of the main filaments exhi- 

 bited slight protuberances, which were supposed to be incipient 

 branches ; these were sometimes opposed to each other, and sometimes 

 they were not quite in opposition. The sporules varied considerably 

 in size, and were ovate or elliptical. Placed in water between glasses, 

 after a lapse of two days it was found that most of the sporules had 

 germinated, each emitting a single filament, which was sparingly and 

 irregularly branched, and contained some very minute granules. —
