Questions of cometary lifetimes and disintegration rates are important to current theories concerning the origin of comets. Data from recent objective observations are not sufficient for a statistically meaningful discussion of disintegration phenomena. It is necessary to make use of older visual observations, which are often rather vague and subject to personal biases. In spite of the difficulties involved in such a study, it is possible to retrieve useful information from these observations. It has been my goal in this paper to thoroughly utilize the observational material relevant to a meaningful discussion of cometary origins. First, the sources and techniques of the study are described. A discussion of the various sorts of activity is ...
