40 [degrees]  Fair
Partly cloudy but mostly sunny.
Light, chill northerly wind.
Vegetation apparently wholly 
unscathed by recent frost &
snow. Unfolded leaves of spiraea &
other shrubs quite perfect; squills in 
bed front of Museum making a
very handsome show; several
lawns in this neighborhood intensely green.
  Garden birds. 2 Robins, 4 Fox

  Rose & dressed at 11. Gilbert [Robert A. Gilbert]
motored me to Harvard Sq. at
noon to keep appointment with
young Dr. Andrews. He began a
surgical treatment of my teeth &
gums with oxygen and boracie acid [boracic acid]
spray keeping at it for 1/2 an hour.
It had at once an invigorating
effect which has lasted ever since.
Thanks to this I worked steadily all
P.M. writing 6 or 7 letters without
fatigue. Dr. Stevens called this eve.
