Fatal Uncomplicated Measles

Thus we have, in a very limited field of research, briefly touched upon the relationship of the purely descriptive and experimental embryologist as to the methods of approach which each has taken in searching for the truth. The former points out the difficult barriers in the path of his progress. His judgment ofter later proves to be amazingly accurate in spite of the limitations of the methods at his disposal, even though at first his conclusions are not accepted as final proof. The experimentalist can take over the problems by applying a different method of attack and can often, but not always, find the way to a final solution which the descriptive embryologist is not able to obtain. He can take a step forward by a new pathway and can often discover new fields for research unrecognized by his companion in research. As cooperative programs of investigations become more fully developed we shall have a more happy balance between the descriptive and experimental embryologist. We shall then, perhaps, not so often lose sight of the importance of the great contributions which the purely descriptive embryologist is constantly making, even though the experimental method may often yield more spectacular results.
