 be discarded. 



Treatment. Therapeutic treatment has been little tried but 

 the best hope of success would be in cases in which the aspergillus 

 is still confined to the respiratory mucosa. In such cases the 

 non-poisonous fungicides may be inhaled, or injected in solution 

 into the trachea. Sulphurous acid produced by the burning, in a 

 close building, of a mixture of sulphur and alcohol so as to saturate 

 the air to such an extent as can be borne without violent cough- 

 ing may be kept up for half an hour at a time twice daily. Great 

 care is required, especially with birds, to obviate suffocation. The 

 administrator must stay with the patients ready at any moment to 

 admit fresh air by opening doors and windows, when the line of 

 safety is being exceeded. As a tracheal injection a solution of 

 hyposulphite or bisulphite of soda (2 drs. to i quart water) maybe 

 employed. More irritating and dangerous would be inhalations, of 

 chlorine, or iodine, or injections of these in solution. Cadeac advises 

 inhalations of tar, phenol or oil of turpentine, or tracheal injec- 

 tions of solutions of phenol or salicylic acid. He even mentions 

 sublimate, but surely as a lapse of judgment only.

MUCOR RACEMOSUg. 



This representative of the mucorinae, a close relative of the 

 trichophyton, was found by Frank in a polypoid tumor of a 

 horses shoulder. The tumor lay under the upper part of the 

 collar, by which it was often rubbed off, but it was as constantly 

 formed anew. The cryptogam showed an abundant mycelium of 

 large size, with globular conidia situated at its periphery, and re- 

 sembling the mucor racemosus. So far as this contributed to the 

 recurrence of the tumor, it might be remedied by the free use of 

 a fungicide- the standard solution of sulphurous acid protected 

 against evaporation, a saturated solution of hyposulphite or bisul- 

 phite of soda, or the standard solution of iodine.
