✦ Synopsis

A determination of the coiitribution made by tlic grannlosa and theca iiiteriia in the formation of the corpus Inieum is difficnlt, largely because the changes occur with great rapidity and uniformity, and because the basement membrane of the granulosa, ~h i c h is between these tissues, early disappears. While this is trnc even when carefully timed specimens are available from animals having a long cycle, it is especially truc in animals with a short cycle, such as the rat and the mouse.2 I n the mature rat, however, following the daily t,ransplaiitation of the fresh anterior pituitary, thc conditions are somewhat different. As has been shown (Smith, '26, and Smith and Engle, ,271, these transplants induce a cystic condition of the follicles (fig. l).;

Committee reports. Report on patent law

Committee reports. Report on patent law revision**The evidence in support of the Preambles and Resolutions and suggested additions to the copyright, patent and trade-mark laws contained in the first part of our report was not published in the May Journal owing to want of space. I am now sending you the remaining part of the report, by request, as it is considered quite necessary for the members of the Association to have in their hands before the next annual meeting, the entire document for consideration and study. It is believed that this will decidedly facilitate matters and save much time at the annual meeting which otherwise might be used up in unnecessary discussion of the subject.Your Committee wishes to again emphasize that fact that we have no desire to impose our personal views on the Association. The copyright and patent laws were designed to promote progress in science and the useful arts and the trade-mark laws to protect the public from fraud and imposition. It is generally conceded that the laws as now interpreted and applied fall short in accomplishing their purpose. It is therefore incumbent upon the A. Ph. A., representing the pharmacists of America, to suggest proper modifications of the law, of such kind as to secure the very important objects for which they were enacted.—F. E. Stewarcth, Chairman.
