masses all over, I divided it into several square pieces, of the 

 size of an inch, and wrapped them up in paper, putting them 

 back to the same place where they had been getting mouldy, 

 some after having been previously treated with the above re- 

 agents. 



The following experiments were made : 



June 8th, 1855. 



1. A piece of bread, luxuriantly covered with mould and heaps 

 of spores, was brushed over with Tinct. Veratri albi on one side, 

 whilst the other was left untouched. As soon as the tincture 

 touched the mouldy threads they shrivelled up, whilst the heaps 

 of spores soaked up the tincture with great avidity, so as to make 

 the wetted spot look as if it had been treated with oil. 



2. Another piece of equal size was wetted with- a solution of 

 Cuprum aceticum (1 part to 100 parts of water). The mouldy 

 filaments, as well as the heaps of spores, allowed the solution to 

 run off, and retained only a few drops similar to the drops on the 

 plumage of water-fowls after bathing. The water carried, how- 

 ever, mechanically away a greater or lesser quantity of spores, or 

 else the latter were brushed off by the drops of the solution, and 

 sent flying about in small clouds of dust, and not the least ab- 

 sorption or retention of the solution on the fungus was dis- 

 cernible. 



3. A similar piece was treated with a solution of corrosive 

 sublimate (1 part to 500 parts of water). The same phenomena 

 presented themselves as in No. 2. 



4. Another piece was brushed over with Aqua phagad. phar- 

 macop. Wurtemberg. 



5. Ditto, with a concentrated watery solution of tannin. 



6. Ditto, with a concentrated watery solution of borax. 



7. Ditto, with Aqua Creosoti ; and 



8. Ditto, with Aqua Picis, with precisely the same result as in 

 No. 2. 



9. A similar piece was brushed over on two sides with Un- 

 guentum Picis. The filaments of mould shrivelled up at once, 

 and the heaps of spores could be smeared with the ointment 

 without causing clouds of dust to rise. 



10. Other pieces were preserved.
