POWDER FOE MAKING BEER. 



A German chemist has invented a dry mass or powder for 

 making ale, extracted from a vegetable, which is very cheap 

 and to be had everywhere, and by which can be produced a 

 wholesome and agreeable ale or small beer of any degree of 

 strength, of the best and purest quality, without adding 

 anything but the proper quantity of water, at every season, in 

 greater or less proportions, and at a very cheap rate. 



To the Editor of the Philosophical Magazine and. Jonrnal. 

 Dear Sir, 



I beg to acknowledge my obligation to Mr. Stockton, for his 

 readiness in fornishing you with the annual depth of rain at 

 New Malton since the year 1816, and by that means correct- 

 ing my statement in page 237, in which I had only given the 

 mean annual depth for the last three years, as he supposes, not 

 having had by me your Magazine for a longer period. I am 

 glad to find by Mr. Stockton's complimentary remark, that the 

 diminution of the mean depth for a longer series of years does 

 not lessen the value of my article. I am, yours, &c.
