nais that use a review system, and there are surely lower limits that can be reached in the time intervals for cer­ tain stages of the review process. Nevertheless, the editors are constantly attempting to improve procedures. The following excerpts are also taken from, the questionnaires in response to the question concerning expansion or improvement in editorial coverage. "I would like to see more articles dealing with wet chemical methods, be­ cause not many laboratories are equipped with expensive instruments." "I would prefer articles emphasizing wet techniques with a little less of the GLC articles." "A disproportionate amount of space is devoted to gas chromatog­ raphy. This is a useful analytical tech­ nique, but there are two other journals serving this field." "I would like to see more articles on X-ray absorption, fluorescence and dif­ fraction, and electron probe micro­ analysis." "I think there is a little too much on gas chromatography in recent years." There were several comments of this general type, so it is worthwhile to ex­ plain why it appears that a dispropor­ tionate amount of space is often given to original papers dealing with one par­ ticular type of instrument or method. An answer to this is found in the article "Publication at the Crossroads," which appeared in this Journal last year

[ANAL. C H E M . 37, 27A (April 1965)] :

"This type of 'surge' in the literature is not uncommon. A few years back there was a surge of papers on organic reagents. Before that the main topic was infrared analysis, and a few years before that a surge in the literature on x-ray analysis followed Hanawalt's classic paper. Gradually x-ray and in­ frared methods and organic reagents took their place as tools for the analyti­ cal chemist, and we can predict the same fate for gas chromatography as time goes by." Therefore, the essence of the prob­ lem is that the types of papers that are appearing in the Journal at any one time reflect the amount of research that is being done in each particular area at any one time, and the Journal editors have little or no influence on that. Despite the fact that 87% of the 866 respondents favored the general pres­ entation and overall appearance of the Journal, there were a few comments that revealed the disparity of aesthetic likes and dislikes among the readers. The editors are considering these and the many other comments, and are sure that they will be of great value in plan­ ning for a better ANALYTICAL ISTRY in the months to come.

PRICE ONLY $2940 New standards of reliability and performance are features of AERO VAC's improved AVA-1 Vacuum Analyzer. The AVA-1 is unmatched in its ability! to make three different measurements from a single nude ionizing sourcej' flanged to your vacuum chamber. No tuning adjustments are necessary with the AVA-1 and, besides having a direct read-out meter in torr, it has a plug-in jack for a remote meter. Other features include continuous scan—2 minutes or 30 seconds; non-contaminating filaments, χ and y recorder outputs, and rhenium or tungsten filaments.
