the liver. There are no other lesions described in the internal 

 organs although Neal writes that any tissue may be invaded. 

 § 175. Treatment. On the ground that the fungus sup- 

 posed to be the cause of this disease may be closely related to 

 the ray fungus of actinomycosis, the use of iodide of potas- 

 sium has been recommended. It is reported to be fairly suc- 

 cessful. The efficiency of this drug as a specific needs further 

 confirmation.

PNEUMOMYCOSIS. 



§ 176. Species of fungi. The literature contains a num- 

 ber of reports of cases of mycosis in the lower animals as well 

 as in man due to infection with different moulds. The genus 

 Aspergillus seems to infect and to produce lesions in animals 

 more frequently than the members of other genera. In fact, 

 Aspergillus fiimigatus seems to be the only important pathogenic 

 species. The lesions encountered as a result of its invasion are
