Zooarchaeologists have used several methods to assess the relative dietary contribution of species found at archaeological sites. The most common methods are either based upon the assumption that bone weight is a fixed percentage of total body weight, or require estimating an "average" body size for identified taxa. In fact, the relationship between parameters of bone and body mass is generally allometric and can be described by linear regression. Use of allometric models places original body mass predictions on a more sound biological basis and makes calculations of "average" weight unnecessary. The potential of allometry is discussed and objections addressed with the goal of encouraging others to develop allometric formulae and to use them in their research.

In recording the history of chemical education in America from 1870 to 1914 notice must be taken of (1) the great advances made in the schools themselves in buildings, equipment, personnel, and number of students. This period includes also (2) the rise in influence and importance of the land-grant colleges and the institutes of technology, (3) the combat on behalf of the sciences for recognition by those who had been devoted to the classics, (4) the beginning of most of our distinctly chemical American publications, (5) the founding of the American Chemical Society, and lastly (6) the general recognition of the value of research and the firm establishment of the American graduate schools.In summarizing his excellent and comprehensive article on "The History of Chemistry Teaching in American High Schools" just published, Paul J. Fay (1) states:Its position in the curricula of high ' schools was firmly established shortly after the middle of the nineteenth century.

veloped influenza except one, who began to feel sick within a few hours after his first treatment. It seems certain his case had developed before taking the treatment.Up to February 9 the actual number of cases reported in the town approximated I jo, or about one in each 40 inhabitants, but one-third of these developed before the treatments began.
