Study Collections were used by 660,740 pupils in the 
city public day schools and 79,358 pupils in the vaca- 
tion schools. The demand for the sets has increased 
so that the Museum last summer procured an automo- 
bile to facilitate delivery to the schools. ‘The specimens 
in the collections have been selected with a view to supplying material 
required in the Syllabus of Nature Study issued by the Board of Edu- 
cation, and there are now thirteen of these collections, containing in all 
five hundred sets. The collections and the number of pupils in the 
ordinary schools using them are shown in the following list:
