Ill December and January there were various occasions on which frost and thaw 
rapidly alternated ; and the resulting effect upon the urea was one of confusion, as is 
seen in the following Table : —

Increase in the urea evolved occurred with increase of urine, and the latter alternated 
in quantity from the varying influences then existing. At the same time constipation 
of the bowels occurred, and the system became disordered. 
Dec. 30. — With a rapid thaw and an increase of 12°‘4 of temperature the urea 
increased 28'9 grs. on the following day. The urine was so low as 30‘3 oz., but rose on 
the following days to 70‘8 oz. and 64 oz. 
Jan. 11. — With thaw and increase of 6°T of temperature the urea remained station- 
aiT and high, but fell on the following days with frost and falling temperature. The 
quantity of urine was very low, and yet fell from 42‘5 oz. to 37’6 oz. on the same day to 
26 ’6 oz. on the following day, and then rose to 64 oz. with decreasing temperature. 
On April 24, with 7°'8 increase of temperature, the urea rose greatly on the same and 
on the following day. The excretion of urine was very high, and it increased to 76-7 oz. 
on the same, and fell to 45‘7 oz. on the following day. 
On July 11, ■with 5°'6 increase of temperature, the urea was lessened on the same and 
on the folloTvdng days until the fourth day, when it rose 92 grs. with increasing tempe- 
ratiu’e. 
Whilst in a majority of instances the influence of temperature acts on the day 
following any important change, it sometimes acts on the same day, and sometimes the 
effect is contrary to the law. The urine is commonly increased with a sudden fall and 
decreased with a sudden rise of temperature on the same day, and the opposite condition 
occurs on the following day. 
There are great oscillations, due to the necessity of maintaining a certain equilibrium 
in the fluids of the body ; and these are set in motion by any act which materially varies 
the emission of fluid, and they continue in a degree and mask the influence of agents 
which in their absence could be traced in the elimination of the urinary products.
