Through the kindness of Mr. A. Kelly of the Irish Education Board andof the institutions in question, three plans of physical laboratories obtainedby this Board in preparing a report upon experimental science relative toeducation in Ireland, are here given. Fig. 46 shows a plan of the Dundee High School laboratory, which isalso used for demonstrations, and contains desks for 18 students. The tablewith siate at each end behind these desks, is used for work in which freedom. 78 LABORATORIES Lecture Roon. /^PfVtR/JTUS C/fS£ /JND LOC/f£fiS Sc/tLE OF Feet 10 s o M l-l M M M t-- /o 20 30 Fig. 46.—Physical Laboratory, Dundee High School.
