per acre gave an increase of 5 tons 8 lbs. of clean mangolds, 

 4 cwts. an increase of G tons 3 cwts. 52 lbs., and 8 cwts. of 

 common salt an inci-ease of 8 tons 14 cwts. 20 lbs. per acre. 



5. As the crude potash-salts used in the preceding experi- 

 ments contained twice as much common salt as sulphate of 

 potash, and common salt gave as much increase as an equal 

 weight of crude potash-salts, it is more than doubtful whether the 

 potash in the latter had any share in increasing the crop on the 

 plots dressed with crude potash-salts. 



(). The preceding experiments, it must be confessed, are 

 rather calculated to demonstrate the utility of common salt as 

 a top-dressing for mangolds, on light, sandy soils, than that of 

 potash. 



It would, however, be rash to decide on the strength of a 

 single series of experiments that the artificial supply of potash, 

 unfavourable as it has proved to be in the case before us, is 

 useless under all circumstances. I therefore wish to suspend 

 my judgment on the practical utility of this and other cheap 

 forms of supplying potash to the land until I shall be in posses- 

 sion of more extensive and reliable practical evidence than at 

 present.

VI. — Statistics of Live Stock and Dead Meat for Consumption 

 in the Metropolis. By Kobert Herbert. 



The heavy losses occasioned by the Cattle-plague in 1866 

 produced a considerable falling-off in the supplies of English 

 and Scotch beasts to the great Metropolitan Market during the 

 last six months of that year. The total number brought forward, 

 including the arrivals from abroad, amounted to only 148,320 

 head, against 181,400 in the corresponding period in 1865, being 

 a deficiency of 33,080 head. But, since nearly two-thirds of the 

 English beasts and nine-tenths of the supplies from Scotland 

 came to hand in far better condition than in the previous season, 

 the falling-ofF in the quantity of meat was trifling. Indeed, we 

 believe that London was far better supplied with animal food 

 than at any time since 1864. This may appear somewhat 

 strange, considering that about 250,000 bullocks were carried off 

 by disease in 1866, and that the importation of live stock from 

 certain districts in Holland has been prohibited. But it may 

 be observed, that the slaughtering of stock in various parts of 

 England and Scotland, for consumption in the metropolis, has
