Study and Loan Material —The main requests for such material 
during the past year have been for Petri dishes, filled with nutrient 
agar and sterilized ready for exposure. Several high schools, as 
well as the Brooklyn Training School for Teachers, availed them- 
selves of this opportunity, and about 250 Petri dishes sent by these 
schools to the Garden were prepared and returned to the schools 
for use in their study of bacteria and molds of the dust and air 
of the schoolroom. 
A few requests from schools for plant study material have also 
been filled; but our facilities for handling such requests remain 
at present very meager, owing to our crowded quarters, as well as 
to inadequate assistance in the collecting and preserving of such 
material.
