THE EAR-FUNGUS.

What has been said concerning Pacings fungus is also to be said 

 concerning the fungus here mentioned, for the representation and 

 description of which I am indebted to Professor R. Leuckart. The 

 fungus was found in 1848 at Gb'ttingen in the stomach of a dead 





woman. The numerous ramifications of the threads had produced 

 such a matting together, that a well-formed membrane was found on 

 the mucous coat. The sporangia were ~" , the shaft or stalk T 5 '", 

 the individual spores ~" in diameter. The individual spores re- 

 sembled yeast-cells. On the grounds mentioned above, for the 

 present I shall give this fungus the name of Aspergillus Leuckartil. 

 Page 231. Mucor mucedo. Herr Hofrath Hasse in Heidel- 

 berg, had the kindness to send me, through c . % /^, 

 Dr. Wagner of Leipzig, a fungus found in 

 the interior of a gangrenous abscess of the 

 lung. Dr. Welcker determined the 

 following principal facts, which I can only 

 corroborate by the microscopical prepara- 

 tion kindly sent me. It occurs in the 

 form of thallus-threads about 0-308 mm. 

 in length, by a breadth of from 0-0026 

 to 0-008 mm. The shaft always in- 

 creases more in breadth towards the top 

 = sporangium, till it attains in the round 

 sporangium to a breadth of 0-025. mm. 

 The stalk is hollow in the interior, so that 

 if it is broken across, one can see within 

 through its transparency, or if it becomes 

 dried up in part, air finds its way into 

 it, which is sometimes met with in the 

 sporangium in the form of a small round 

 bubble. The spores are 0-0036 to 40 

 mm. in length, and have in breadth a diameter of from 0-0015
