Il. MONTHLY RESULTS. 
Monthly observations on a considerable number of Conifers 
were not begun till 1882, and the results for the five years ending 
1886 have already been given.! This set of comparatively old 
trees were then, perforce, given up, and a younger set were 
observed for a second five-years’ period, 1837-91. As the results 
for these have also been published,? and as my monthly records 
of Conifers then ceased, I shall only give some of the general 
conclusions arrived at in these earlier investigations.
