water containing a quarter of an ounce of creosote. No 

 beneficial effect was produced. 



5. Milk of lime was tried, and the disease in the potatoes 

 was hastened. 



6. The kiln-drying of potatoes, under various circum- 

 stances, has been tried with success. 



7. Potatoes have been placed in dried clay or soil. The 

 disease was stopped in all the potatoes so stored. 



8. The disease increases if the potatoes be immersed in 

 running water. 



9. The temperature of potatoes in the natural state was 

 54j ; those dipped in the vitriol mixture above mentioned, 

 53 ; those dipped in creosote, 56 ; those in milk of lime, 

 55 ; those fumigated with sulphur, 52^ ; those stored in 

 dried clay or soil, 5 2 I \ those in natural state, becoming 

 diseased, stored in cask three days and untouched, 64^. 

 These potatoes were as nearly as possible under the same 

 circumstances. 



10. That the committee feel unable to give too much 

 prominence to the fact, that exposure to light and air, in a 

 dry place, with frequent turning of the potatoes, excluding 

 those far advanced in disease, are quite sufficient to prevent 

 the disease from doing much injury. 



Mr. Moore, Mr. Clare, and Mr. Leigh, waited upon the 

 Mayor of Manchester, on Saturday, November 1 5, at the 

 Town Hall, and were very graciously received. 



The Mayor, having informed the committee, that at an 

 interview with Sir Robert Peel, at Drayton Manor, on the 

 previous Thursday, the Premier had expressed himself 

 much gratified that the very important question of the 

 potato disease had been taken up by the Literary and 

 Philosophical Society of Manchester.
