Of these papers, 16 were read in 1867 ; 13, in 1868 > 
and 17 in 1869. In all Natural History Societies 
the number of individuals who provide papers are 
few in comparison with the total number of members, 
and in this respect the Perthshire Society of Natural 
Science presents no exception to the general rule j 
for I find that the 46 papers above mentioned have 
been provided by 10 individuals. They, and the 
number of papers communicated by eachj are as 
follows :— 
13 papers.

In addition to the regular monthly meetings of the 
Society, excursions have been made on several oc¬ 
casions. At these I have not had the pleasure of 
being present, as the season for making excursions is 
during my absence from Perth ; but I regret to learn 
that they have not been so successful ais might have 
been wished. This has probably arisen from the 
difficulty of finding a sufficient number of members 
who can absent themselves at one time from their 
other duties. Even with this difficulty before ib, the^ 
Bociety, I think, should be very unwilling to relind 
‘quish the idea of excursions altogether, and I would 
suggest that the example of some other societies and 
field clubs be followed, and that we should have an 
Annual Field-day, and make an excursion, at which 
every member (who. possibly can) should endeavour 
to be present. This excursion might be carried out 
thus :—All the members and their friends who can 
get away should start at an early hour in the fore¬ 
noon, and, either in one or more parties, make a 
thorough examination of the district to which the 
excursion is made. Let there be a certain hour (to¬ 
wards the end of the afternoon) and place appointed,
