SCIENCE. 



559 



It would be difficult to notice in a short 

 account like this all the important exhibits 

 that ought to be mentioned from a scientific 

 standpoint. In fact, each department con- 

 tained materials which were praised most 

 highly by those qualified to give praise 

 from a scientific standpoint. As one en- 

 tered the large hall one was greeted with 

 a magnificent display of the astronomical 

 results of the year, including photographs 

 of the moon, stellar spectra, etc., which at- 

 tracted a great deal of attention from the 

 many astronomers present. Oa the right 

 was to be seen the equally attractive exhi- 

 bition of paleontology, including the several 

 fossil reptiles which were unearthed last 

 year by the American Museum of liatural 

 History, and which are the greatest finds 

 in vertebrate paleontology thus far made 

 by this institution in the far West. The 

 other exhibits in the outer hall included 

 chemistry, philology, mineralogy, experi- 

 m^ental psychology and ethnology. The 

 exhibit in philology was large and compre- 

 hensive, and received a good deal of atten- 

 tion. This is the first time that this 

 department has ever made an exhibit, 

 although there has been a Section of Phi- 

 lology in the Academy for some time. The 

 exhibit iu experimental psychology in- 

 cluded several instruments for psycholog- 

 ical measurements, exhibited by Professors 

 Cattell, Bliss and others. The exhibit in 

 ethnology contained a few of the best results 

 obtained by the Jesup North Pacific Ex- 

 pedition during the last year, and illus- 

 trations of symbolism of the Huichol In- 

 dians of Mexico. In chemistry, beside the 

 exhibit of liquid air, the representation and 

 processes of dyeing from the Columbia Labo- 

 ratory, and the more recent results in the 

 artistic coloring of glass from Tiffany & Co., 

 received the most attention. The exhibit 

 in mineralogy was very carefully arranged, 

 and included some very wonderful crystals, 

 and several minerals from Tasmania and 



New South Wales, exhibited by Dr. A. E. 

 Foote. 



In the second hall devoted to the exhibit 

 was found on the right, first, the exhibit in 

 botany, largely devoted to microscopical 

 and other preparations iu morphologj', and 

 the exhibition of new species and genera 

 from various parts of the United States. 

 Indeed, several hundred feet of wall space 

 were attractively and artistically covered 

 with herbarium specimens illustrating 

 these points. In anatomy the large series 

 of preparations of the anatomy of reptiles 

 exhibited, by the Department of Anatomy 

 of Columbia Uoiversity, was striking, as 

 showing the latest results in staining, 

 preparation and mounting. An equally 

 attractive exhibit was made in the depart- 

 ment of zoology, including the results in 

 insect coalescence, oa the several Puget 

 Sound expeditions of Columbia University, 

 and the expedition to Bermuda of the 

 New York University in 1897. On the 

 same side of the hall there was a good- 

 sized exhibit in photography, including an 

 illustration by lantern of colored photog- 

 raphy, and tlie latest papers and developers 

 and their results. 



On the other side of the hall, as one en- 

 tered, was to be seen the large exhibit in 

 geology, in which mention should be made 

 of the clays and other specimens from Eu- 

 rope collected by Dr. Heinrich Ries in his 

 studies of kaolins and clays abroad. The 

 most beautiful exhibit was that of the 

 leucite and trachytic rocks of the Italian 

 peninsula, of Mr. Henry S. Washington, of 

 Locust, N. J.; also photographs and speci- 

 mens illustrating recent experiments in 

 compression and flowage of marble carried 

 on at the McGill University, Montreal, 

 should be mentioned. The exhibit in 

 physiography included a large number of 

 maps of the United States Geological Sur- 

 vey mounted for physiographic uses, the 

 Harvard Geographical Models, a model of
