Some Books Recently Received: Seaplane Design—Standard Engineering Symbols and Abbreviations—War According to Germany Available to Purchase

The writer of “Seaplane Design” is to be congratulated on the industry and care with which he has consulted the published literature on his subject. He gives a full account of most of the recent work, both experimental and theoretical, which has been done in the United States and Germany. Unfortunately, he has not taken into account the still more recent work published in this country, possibly because his book was prepared some time ago. Research work on seaplanes, both model and full scale, is advancing so rapidly that in some respects a book on seaplane design is almost out‐of‐date before it is published.
