SCIENGE. 



609 



above as being the most attentively studied, 

 there were many other exhibits worthy of 

 mention, of which only a few can be spoken 

 of here. In chemistry, besides the exhibits 

 noted, the most interesting materials were 

 the artistic glasses exhibited by the Tiffany 

 Decorative Companj^, and several striking 

 pieces of apparatus exhibited by the chair- 

 man. 



In electricity the enclosed arc lamps, 

 the Crookes tubes and fluoroscopes received 

 a great deal of attention. In ethnology 

 and archseology the busts of the Kwakiutl 

 Indians and the paintings, diagrams and 

 specimens illustrating the culture of the 

 primitive American races were the more 

 notable exhibits. 



In geology the exhibit of clays from 

 various parts of America and the products 

 made therefrom won a great deal of well 

 deserved attention. The photographs from 

 the Cornell Greenland expedition illustra- 

 ting some of the conclusions of Professor 

 Tarr regarding the effects of glaciers in 

 Greenland were of interest both to the un- 

 scientific and the scientific. The associated 

 subject mineralogy had on exhibition a large 

 series of new and valuable specimens which 

 cannot be noted here in detail. In 

 paleontology was one of the largest exhib- 

 its that took the greatest amount of labor 

 in arranging. The exhibit included fossils 

 from some of the more important locali- 

 ties illustrating the work accomplished by 

 leading paleontologists of the East. Be- 

 sides the stratigraphic collections exhibited, 

 there was a large series of fossil insects from 

 Florissant, Colorado, including some very 

 handsome butterflies exhibited by Mr. S. 

 H. Scudder. The preparations of Beecher, of 

 Yale University, illustrating the structures 

 ofTrilobites, were much studied, represent- 

 ing, as they do, the best knowledge of what 

 hasbeen until recently but little known. The 

 fossil gums including insects of all kinds 

 also deserve a note. In vertebrate paleon- 



tology there was a large collection of fos- 

 sils from the American Museum, and some 

 striking water colors of the reproductions 

 of extinct mammalia. 



The exhibit in photography included 

 some very beautiful prints and some of the 

 more recent apparatus, and received much 

 attention. It was, however, disappointing 

 to those in charge because so many exhib- 

 itors failed to send promised materials, some 

 of which were of especial interest and value. 



In physiography the exhibit included 

 several large models of New England and 

 New York, representing the newest and 

 best work of Mr. Howell, of Washington. 

 A series of teaching models from Professor 

 W. M. Davis, which have just been cast, 

 also were exhibited uncolored. These 

 models represent the best work of the year 

 outside of the numerous publications. 



In zoology the most important exhibition 

 was the collection of animals from the 

 Puget Sound region, exhibited by Columbia 

 University. Many of the forms represented 

 were shown in all stages from embryonic to 

 adult and are very valuable additions to 

 our knowledge of the lower animals. The 

 plans and models of the new Zoological Park 

 of New York City also were shown in some 

 detail and naturally received very much 

 attention. 



The Exhibition represents a large in- 

 vestment of time and labor on the part 

 of the few in charge, and shotild bring very 

 valuable results to the Academy in many 

 ways. It has aroused considerable interest 

 in many places at a distance from the city, 

 and it is hoped that the plan of having such 

 exhibitions may be followed by other scien- 

 tific societies in the country. If scientists 

 would have the support of the public they 

 must show their work. There is no better 

 way to show work than by a scientific ex- 

 hibition in which the popular and wonder- 

 ful are exhibited together with the more 

 valuable and enduring. The committee in
