short ranges an empirical formula of the Gordon type could be 
found for each range which would represent experimental results 
much more closely. 
4. The subject of beams with endlong compression does not 
appear to have been tested by experiment to anything like the 
extent that the interest and importance of the subject would 
justify. 
The strut-beams tested by the author had their lateral loads 
concentrated at the centre, but perhaps a more interesting case still 
would be that of a uniform lateral load such as is obtained in the 
coupling rods of a locomotive or in a horizontal strut loaded by its 
own weight, or in other ways. 
The above experiments were carried out in the Engineering 
Laboratory, and the author’s thanks are due to Professor Ewing 
for providing the facilities for the investigation.
