298 DR, ROBERTS ON THE DIURNAL VARIATIONS, ETC. 
Cane sugar and honey do not seem to possess any power 
of diminishing the excretion of acid by the kidneys. The 
evidence is rather the other way; for although the ten- 
deucy to a rise after breakfast on the two days is too slight 
to insist much upon, yet it is very notable that the honey 
and sugar prevented the fall that would otherwise have 
taken place from mere prolongation of the fasting. The 
hourly flow kept up without appreciable change until about 
the seventh hour after the saccharine meal; then there 
occurred a marked declension. 
The absorption of the sugar and honey was far from 
rapid; for sweet eructations took place for four and five 
hours after their ingestion, showing that the stomach was 
still hampered with their presence. Some considerable 
difficulty was experienced in swallowing and keeping down 
these large doses. It is worthy of note, that the second 
dose of cane sugar produced a most copious, though eva- 
nescent, diuresis. Not less than 7780 grain-measures of 
a watery urine were produced in forty minutes, or at the 
rate of 264 fluid ounces per hour, presenting a remarkable 
contrast to the flow five hours later, when only 166 grain- 
measures were secreted per hour, or at a rate seventy times 
slower than during the first period.
