Also, steps were taken looking to the appointment of a special committee to confer with the several scientific and educational institutions of the State, with the view of establishing a Weather Service on the lines suggested by the Maryland State Weather Service.
To increase the interest of the general membership of the Institute in the Section, it was decided to endeavor to devote more attention, if practicable, to the subjects usually included under the name of Terrestrial Physics. Also, the name of the Section was changed, by authority of the Board of Managers,. to " The Physical Section " of the Franklin Institute.
