is written as an exponent of the date, and since all experiments 
were made during daytime, no designation of A.M. or P.M. is 
required. As in previous work, interest centres chiefly about 
the nucleus. Change in this is expressed in percentage of 
loss or gain, using the original volume as 100 per cent. Time 
in hours and minutes, from beginning of experiment, is written 
as an exponent of the shrinkage per cent. Where several cells 
were watched, each bears its proper number throughout the 
experiment. Controls enter the table only in case some 
change is noted in them. No significant change in size of 
cell body was observed, hence their omission from table. 
Experiments I and 2 were made with cells of sympathetic 
ganglia. In all the rest the spinal ganglia were used.
