    Excerpt from Illinois Biological Monographs, Vol. 3 The present studies of the factors controlling rate of regeneration are a continuation of previous work on the subject. An advance in knowledge concerning certain of the factors has made possible an extension of the experimental analysis of others. The present studies are therefore closely related. In fact in several cases a single series of individuals has been of value in connection with more than a single factor. The definite determinations of the effect of level of the cut and of the change in rate during the regeneration cycle have been of particular value. The precautions taken to meet the demands of the experiments are not discussed in detail because they have already been given in previous papers. The frog tadpoles (when they can be used) are in all respects more suitable than salamander larvae. When collected late in the fall they can be kept at a fairly constant size and the results obtained under these conditions are not complicated with growth phenomena. They have proved to be remarkably uniform in several series. The salamander larvae on the other hand vary in rate of regeneration from day to day. The factors involved in this fluctuation were not discovered and could not be remedied but may be related in some way to the fact that these animals require living active food and the feeding reactions are therefore more complicated than in frog tadpoles and more subject to disturbance. In regard to certain factors, such as the degree of injury, in which expected differences in rate are slight the writer has felt that he might be biased in making the measurements and in a number of cases this work was therefore delegated to a person who had no preconceptions concerning the result. In making averages elimination of individual cases is avoided except for a few very aberrant values. Such exceptional values are in every case however included in the tables. In many cases where only slight differences are to be expected several different kinds of comparisons are made so as to bring out the correct relation as completely as possible. As in the past all data obtained by the writer on the particular factors in question are given. The practice of selective elimination would be dangerous because of the large value of factors not at present under experimental control.
