Excerpt from Biological Bulletin of the Marine Biological Laboratory, Vol. 6: December, 1903, to May, 1904 As the rate of regeneration varies with the size of the animal as well as with the number of removed arms the proper relations can best be represented by means of curves. The figure aecom panying this paper gives the average of Series I. And II. (those with respectively one and two arms removed) in one curve and of Series III. And IV. (those with respectively three and four arms removed) in the other. The same arrangement is followed for each of the three measurements taken respectively 22 days, 33 days and 46 days after the operation. This brings out the de sired relations more clearly than would have been possible if all the individual data had been included. In the figure the abscissa give the size of the animal as represented by the disk diameter in millimeters. The ordinates give the length Of the regener ating arm or arms, also in millimeters. In the series where more than one arm was operated on the regeneration length as given is an average of all the regenerating arms of the individual. As the individual disk diameters are not exactly equivalent in the different series it was found convenient in taking the averages for the combination curves to use arbitrarily disk diameters equal to whole millimeters as the points for comparison. The curves in the figure are therefore constructed on this basis. The unbroken line in each case gives the average of Series I. And II. (one and two arms removed) and the broken line of Series III. And IV. (three and four arms removed). About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
