534 Account of Experiments 



was kneaded the first, and at a quarter before lo the 

 second time ; and in the course of half an hour 

 1 60 loaves were made out of it, which were put into 

 the oven at 10 minutes before 11 o'clock, and taken 

 out again at 8 minutes before 12 o'clock at midnight. 



The water used in making the dough for this batch 

 of bread was 137 lbs. 5 loths. 



Sixth Heating of the Oven. — At a quarter after 

 8 o'clock, the sixth and last fire was made with 40 lbs. 

 of wood, to which, at 15 minutes before 10 o'clock at 

 night, 34I lbs. more were added ; so that in the last 

 heating 74! lbs. of wood only were consumed. 



General Results of these Experiments. 



The ingredients employed in making the bread in 

 these six experiments were as follows, viz. : — 



Of rye-meal , 



water 



salt 



In all . . . 



Of this mass 1 102 loaves of bread were formed, each 

 of which before it was baked weighed 2I lbs. Conse- 

 quently, these 1 102 loaves, before they were put into 

 the oven, weighed 2755 lbs., but the ingredients used in 

 making them weighed 2812 lbs. 5 loths. Hence it ap- 

 pears that the loss of weight in these six experiments 

 — in preparing the leaven, from evaporation before 

 the bread was put into the oven, from waste, etc., — 

 amounted to no less than 57 lbs. 5 loths. 



In subsequent experiments, where less water was 

 used, this loss appeared to be less by more than one 

 half.
