SYSTEMATICALLY SELECTED YEASTS. 63 



berg fermenting cylinder, in that they have made it somewhat 

 higher, and have arranged for the wort to enter at the upper 

 portion of the cylinder, within which is fixed a pipe in the 

 form of a ring and provided with small holes ; the wort pass- 

 ing out of these holes washes down the sides of the cylinder, 

 so that any yeast or froth which may have collected from the 

 previous fermentation is carried down into the fermenting 

 wort, and permanent accumulations are thus prevented.* 



* Captain Kiihle and I have not patented our apparatus, and anyone is, 

 therefore, at liberty to make it. To those who wish to use it, however, we 

 recommend the cylinders made by Mr. W. E. Jensen, of Copenhagen, as he has 

 taken part in the construction of the apparatus, and is thoroughly familiar with 

 it. Below is given Mr. Jensen's price list :

The air-pump and air-holder can be obtained anywhere. A suitable air- 

 pump costs about ^22; an air-holder with a capacity of -f- cubic meter and 

 tested to five atmospheres, costs about 2%. 



To prevent misunderstanding, it may be pointed out that neither Capt. Kiihle 

 nor myself have any control over the manufacture of the above apparatus, and 

 therefore no responsibility rests with us. Neither can we undertake to answer any 

 questions, or to execute any orders for the apparatus. It is requested that all 

 enquiries should be sent direct to the manufacturer with whom it is intended to deal.
