✦ Synopsis

THE cement reference laboratory, established during the last fiscal year as a cooperative effort of Committee C-I on Cement of the American Society for Testing Materials and the Bureau of Standards, to promote uniformity and improvement in cement testing, has been engaged for several months in field inspection of cement laboratories.

The inspectors may not visit some localities for considerable periods of time, and on that account the following tolerances on apparatus should be of interest to those laboratories which desire to examine and adjust their apparatus or write purchase specifications for new apparatus.

It should be understood that these tolerances are '(proposed tolerances," and have not at this time any official standing as accepted standards or tentative standards of the 'American Society for Testing Materials.

However, the cement reference laboratory is operating under these tolerances.

Initiation factor-free 30S subunits of E. coli ribosomes bind aminoacyl-tRNAs more efficiently than fMet-tRNA(fMet). Elongator-tRNA binding was unaffected by IF-1 or IF-2 but was inhibited by IF-3. Their combination reduced this binding up to 40% and stimulated that of fMet-tRNA(fMet). Unexpectedly,
