TABLE OF BAROMETRICAL HEIGHTS TO 20,000 FEET. Computed by William H. Mackesy. The tables are mainly intended for use with the compensated mountain aneroid barometer but they are also suitable for the mountain mercurial barometer. A valuable little set of tables.
THE ATMOSPHERE ITS CHARACTERISTICS AND DYNAMICS. By F. J. B. CORDEIRO. In producing this work the author has endeavored to place before the public valuable data and information collected by him as to the origin of hurricanes, their causes and other atmospheric disturbances. In view of the fact that so much interest is now being taken in the navigation of the air every scrap of information that can be collected relative to atmospheric conditions will prove of considerable value to all those interested in this new science. The work is divided under the following headings:—Constitution. Temperature and density. Convective equilibrium. Various atmospheres. Aqueous vapor. Pressure of air. Practical barometry. Motion relative to the moving earth. Vertical motion. Horizontal motion. Frictionless motion over a rotating spheroid. Motion on the rotating earth without friction. General circulation of the atmosphere. Equatorial circulation. Polar Circulation. Middle circulation. Planetary circulation. Cyclones. Porto Rican hurricane of August 8, 1899. Horizontal velocity. Tornadoes. Other Phenomena occurring in the atmosphere. Sound. Merged explosions. Optical phenomena. The rainbow. Atmospheric conditions in relation to flying machines, etc. With numerous tables and 34 illustrations, 4to. Paper covers $1.50, full cloth, $2.50 net.
THE THEORY AND PRACTICE OF MODEL AEROPLANING. By V. E. Johnson, M.A. The object of this book is to give in plain language the general practice and principles of Model Aeroplaning. Model propellers and motors have been carefully dealt with, and much valuable data included from the author’s own experiments. Contents of Chapters.—Glossary of Terms used in Model Aeroplaning. Introduction. The Question of Weight. The Question of Resistance. The Question of Balance. Motive Power. Rubber Motors and other forms of Motors. Propellers or Screws. The Question of Sustention. The center of pressure. Materials for Aeroplane construction. Hints on the building of Model Aeroplanes. The Steering of the Model. The Launching of the Model. Helicopter Models. Experimental records. Model Flying competitions. Useful notes, tables, formulae, etc., etc. 163 pages, 82 illustrations, 12mo cloth, $1.50.
