In last year's Report the statures and weights of three groups of schools were given.
Group A.—(English measures originally) chiefly poorer class schools.—Ackmar.road, Beaufort
House, Glenister.road, Old Woolwich.road, and Columbia.road, including 3,038 boys and 3,084 girls.
Group B.—(Measurements taken on the metric syBtem) in the Acland, Burghley.road, Gipsy.
road, Bellenden.road, Dulwich Hamlet, Bell.street, Buckingham.street, Rosendale.road, Honeywell.
road, Michael Faraday, and Salters Hill Schools. With two exceptions these might be described
