Excerpt from Transactions of the American Microscopical Society, Vol. 20: Twenty-First Annual Meeting Held at Syracuse, New York, August 30, 31 and September 1, 1898 He was a man whose life was spent in natures great laboratory, and if he had been spared to address us on this occasion, we would have listened to an important chapter from nature study. He taught during his lifetime the existence of higher and nobler ideals. Personally, I am much indebted to the living influence of his forceful character and, if perchance, in my feebleness in trying to do as he would have wished, I shall be so fortunate as to kindle anew or deepen your interest in pure or applied biology, cherish the thought as a reflected message from him who would, had God willed, instructed us this hour. Under the trying circumstances, I had some difficulty in selecting a topic for this formal address. The little time since this unexpected duty fell to me has been so overcrowded with other and more imperative duties, that it was impossible to carry out a new, or even complete, any line of investigation, the results of which could be used on this occasion. Likewise it was too brief for preparing a discussion on any of the broader and more fundamental problems centered in any of the sciences represented in our society. It so happened, however, that following this call to duty, I had occasion to adjust a course of instruction in comparative bacteriology, to meet the needs of students of human medicine, and, at the same time, to fill it full for those who were seeking knowledge in comparative pathology. In working out this actual and seemingly difficult problem, the subject as announced suggested itself and in its somewhat popular consideration I ask your indulgence.

Excerpt from book: DEPARTMENT OF SUMMARIES TO BE DEVOTED TO DIGESTS OF PROGRESS IN BIOLOGY While the Transactions will continue to be primarily a Journal of research in mier-- oiology, it is recognized that the field has become so broad as to preclude the possibihf of freauent articles in any one of the departments of special interest. Because of this it will be the policy to present, from time to time, supplementary digests of the progress being made in the various fields of micro-oioloiiy It is also proposed to introduce similar summaries of the progress made in some departments not represented in our articles of research. This is done with the feeling that such reviews will Increase the permanent alue of the Transactions to all who may not have access to a large list of technical biological journals, nor the time to make the survey for themselves. PROGRESS IN EVOLUTIONARY THOUGHT SOME LATTER-DAY ASPECTS OF DARWINISM. By J. F. Abbott. A lecture given before the faculty and students of Washington University Jan. 9, 1912. If any one thing can be taken as a symbol of the present time, I fancy the most appropriate would be the hammer. Not only is the hammer the symbol of constructive industry so characteristic of our age, but it may also typify the spirit of iconoclasm, which is equally, if not more strikingly, characteristic. From the muckraking of a popular magazine to the calm, deliberate, destructive criticism of a system of philosophy, now is essentially a time of making over. The present generation has no reverence for traditions of the past unless they be in harmony with the point of view of the present. It is by some considered a sort of poetic justice that the image of the greatest iconoclast of modern times, in effect if not in pur- pose, - -Charles Darwin, ?shou.

Excerpt from Transactions of the American Microscopical Society, Vol. 28: Twenty-Ninth Annual Meeting, Held at Ithaca, New York, June 29 and 30, 1906 No more timely subject, it seems to me, can be discussed in a presidential address before the American Microscopical Society than the origin and development of the projection microscope, since by the universality of the electric light many can make use of this most potent means of illustration. When the task was begun it was not thought that the trail would lead so far back into the past nor be so obscure and difficult to follow. In following up the trail it becomes increasingly evident that the records of human achievement are secondary records only.

Excerpt from Transactions of the American Microscopical Society, Vol. 39: January, 1920 From this it is seen that the degree of infestation of the host is comparatively small. Whereas the number of adults met with was quite limited, larvae were very plentiful when present at all. In situ all of the adults and most of the larvae were found free in the stomach or intestine, but many larvae - forty-one in the case of the third fish in the table - were attached to the bottoms of deep pits in the mucosa of the pyloric region of the stomach. These pits were not mere depressions of the wall of the stomach but actual cavities, as shown in figure 7, bordered by a pronounced annular thickening of the mucous membrane and as much as 2mm. In dia meter. Larvae ranging in size from almost the smallest met with to those near the adult stage in development were tightly crowded into these pits and at the same time strongly contracted longitudinally.
