If the linoleum is too fresh and therefore too soft, the test will show bad results, and, the medium being fragile and bad, hard linoleum will also yield bad results. The method has, indeed, been adopted in some other places and is, for instance, followed at the Testing Laboratory of Gothenburg1) and at the Hungarian State-Railways. In the Table XI above is given an account of all the results come to by the Laboratory until the 1st of January 1909. ____________ x) In Gothenburg the method has been found more appropriate than the application of -»Bauschinger’s« machine, see »Baumaterialienkunde« 1904, Nr. 23.
