 Newport, E. I. Addresses of welcome will

 and Hon. Thomas W. Palmer, and Presi- 

 dent Gibbs will reply. Announcements by 

 the General, Permanent and Local Secreta-

On the afternoon of Monday, August 9th, 

 the Vice-Presidents of the Sections will 

 make addresses as follows : 



At half-past ttoo o'clock. Vice-President Barus, be. 

 fore Section o£ Physics : ' Long Eange Temperature 

 and Pressure Variables in Physics. ' Vice-President 

 McGee, before Section of Anthropology: 'The Sci- 

 ence of Humanity.' Vice-President White, before 

 Section of Geology and Geography: 'The Pittsburg 

 Coal Bed.' 



At half-past three o'clock. Vice-President Beman, 

 before Section of Mathematics and Astronomy: 'A 

 Chapter in the History of Mathematics.' Vice- 

 President Colburn, before Section of Social and Eco- 

 nomic Science: ' Improvident Civilization.' Vice- 

 President Howard (nominated by Council to fill 

 vacancy caused by the death of Dr. G. Brown Goode) 

 will give by request of the Council an address before 

 Section of Zoology, subject to be announced. 



At half-past four o'clock. Vice-President Mason, 

 before Section of Chemistry : ' Sanitary Chemistry. ' 

 Vice-President Atkinson, before Section of Botany: 

 'Experimental Morphology.' Vice-President Gal- 

 braith, before Section of Mechanical Science and 

 Engineering : 'Applied Mechanics. ' 



On Monday evening Dr. Theodore Gill 

 will give a memorial address on the life and 

 work of the late President of the Associa- 

 tion, Professor Edward D. Cope. 



The meetings of the Sections will follow 

 on the mornings and afternoons of Tues- 

 day, Wednesday, Thursday and Friday. 

 It is expected that on two days of the week 

 the Geological Society of America and the 

 American Chemical Society will hold meet- 

 ings occupying the time of Sections E and C. 



The usual receptions and excursions have 

 been planned, including a visit to Ste Claire 



Flats, on Saturday after the adjournment. 

 It is expected that the members of the As-

 Toronto to join in welcoming the members 

 of the British Association to America. For 

 this purpose special rates will probably be 

 secured by steamer and train from Detroit 

 to Toronto. 



INTERNAL SECRETIONS, CONSIDERED FU03IA 

 CHEMICO-PHYSIOLOGICAL STANDPOINT* 

 In considering this subj ect from a chemico- 

 physiological standpoint allow me at the 

 outset to emphasize the fact, now well 

 established, that the symptoms which fol- 

 low the simple removal of a physiologically 

 active gland from the body result wholly 

 from the loss of the gland. You may re- 

 call that when attention was first drawn to 

 the possibility of producing the typical 

 symptoms of myxoedema in monkeys by re- 

 moval of the thyroid gland there was a 

 tendency to assume injury to the sympa- 

 thetic or other nerves of the neck as an ex- 

 planation of the phenomena, rather than to 

 admit the possibility even of a general or 

 limited disturbance of the metabolism of 

 the body through chemical changes asso- 

 ciated with removal of the gland. It was 

 not until the experiments of Murray made 

 clear the fact that the effects resulting from 

 the removal of the thyroid in man could be 

 overcome, in part at least, by administra- 

 tion of the gland-substance that scientific 

 investigation took the proper turn and a 

 full realization of the possible importance of 

 the so-called ductless glands and their in- 

 ternal secretions began to dawn upon the 

 mind. To-day, however, we recognize their 

 functional activity as a necessary element 

 for the welfare of the body. Their removal, 

 or any impairment of their function, may 

 produce even more disturbance of physio- 

 logical equilibrium than a corresponding 

 disarrangement of glands formerly consid-
