CHEAP BREAD. 



Take pumpkins and boil ihem in water until it is quite thick^ 

 and with this water moisten your flour. Dough mixed in this 

 manner makes excellent bread: its proportion increases consi- 

 derably, at least one-fourth, and it keeps good a length of 

 time. — E. . 



Birkenmayer, a brewer of Constance, has made an experiment^ 

 which has succeeded, in manufncturing bread from the farinaceous 

 residue of the beer. Ten pounds of this species of paste, one 

 pound of yeast, fi%'e pounds of ordinary meal, and a handful of 

 salt, prodjuce twelve pounds of black brcudj but savoury and 

 nourishing. 



MR. IJyWATER 0]S THE POLYPES. 



To Mr. Tillocli. 



Sir, — Wishing to encroach as little as possilde on your pages, 

 the paper I sent you, and which appeared in your last, was 

 abridged from one of greater length. Unfortunately some am- 

 biguity has thereby been introduced, by retaining a passage in 

 page 284, alluding to some observations which had been ex- 

 punged from another part of the paper. Your readers are re- 

 quested to omit the paragraph between line 36 and line 45, 

 which will considerably diminish the obscurity. 



At the close of the paper an idea is held out that animalcules 

 may exist in vegetables, and extend their race with the vegetable 

 process. That such is the fact I am strongly persuaded; and it is 

 equally probable, from a variety of phaenomena, that the organic 

 structure on which the vegetable process depends, as well as the 

 exquisite design and beauty manifested tliroughout the vegetable 

 kingdom, are derived from the instinctive influence of this nu- 

 tnerous class of active agents. But as an investigation of such aa 

 extensive nature is not comprehended in the oijject of the pre- 

 sent letter, I shall wave the inquiry until a fiiiure opportunity. 



An insertion of these remarks in your next Number will con- 

 fer another obligation on 



Your very obedient servant, 



Liverpool, May 12, 1317. ' JoHN BvWATF.R.
