statement. It forms, without much change, the 25th Chapter of the 

 Treatise on Human Physiology, published in 1887, a second edition 

 appearing in 1899. 



A Manual of Medical Jurisprudence and Toxicology, designed, 

 apparently, merely as an aid to the student in following the lectures, 

 was published in 1892, subsequent editions appearing in 1896 and 1903. 



He prepared an appreciative memoir of Dr. Joseph Leidy for the 

 Academy in 1891. It is an adequate record of the work of his friend, 

 to the value of whose encouragement and guidance he was always 

 delighted to testify. Dr. Leidy's claims to public gratitude were again 

 presented by him in an address delivered in the City Hall on the 

 occasion of the dedication of Murray's statue of the great naturalist, 

 October 30, 1907. 



His paper on The Interpretation of Certain Verses of the First Chapter 

 of Genesis in the Light of Paleontology was contributed to the Proceed- 

 ings of the Academy in 1893. The article must be considered as a 

 mere tour de force. It is not regarded as a contribution to our know-

 interests. 



He was elected a member of the Board of Directors of the Library 

 Company of Philadelphia, April 3, 1902. He took an active interest 

 in the affairs of the Company, serving on the Book and Ridgway 

 Branch Committees. 



Again in Europe in 1902, he gave special attention to the collec-

 Museum, and to those of the Zoological Station of Naples, where 

 he was cordially received by the late Prof. Dohrn, who assisted him 

 in procuring for the Academy a fine collection of the invertebrates of 

 the Bay of Naples. The specimens, prepared with the care charac- 

 teristic of the Station, filled no less than 152 glass jars, and constitute 

 a most valuable addition to the Museum, which had been enriched 

 from time to time by the anatomical material of Dr. Chapman's 

 studies, and by interesting collections from Bar Harbor. 



A few months were spent in Paris in 1903, when he again addressed 

 the Biological Society. He was back in Bar Harbor by the first of 

 July. In 1905 he visited Egypt where he applied himself with charac- 

 teristic energy to the study of hieroglyphics and Egyptian antiquities. 

 He subsequently went to Rome and became intensely interested in 

 the excavations of the Roman Forum. His devotion to this field of 

 research continued unabated and he looked forward with eagerness
