hibits made by the Chairman, Prof. J. G. 

 Curtis, and by Professor Thompson, of the 

 New York I'uiversity. The botanical ex- 

 hibit, arranged by Dr. Carlton C. Curtis, 

 included an extensive displaj' of new plants 

 from North and South America, Dr. .Schnei- 

 der's studies of lichens, and the morphologi- 

 cal and embryological studies carried on 

 under the direction of Dr. Curtis, by the 

 students of Dr. Curtis and of Professor 

 Gregory of Barnard College. 



The American 3Iuseum contributed two 

 extensive exhibits in Zoology and Palaeon- 

 tology, arranged by Professor Allen and Pro- 

 fessor Osborn. The Zoological exhibit illus- 

 trated the rapid improvement in the modern 

 methods of taxidermy by a series of com- 

 parisons of specimens of work just com- 

 pleted and that of ten years ago, the most 

 notable being the prepai-ation of the chim- 

 panzee ' Chico ' by Mr. Rowlej'. Tlie re- 

 sults of the current field explorations of the 

 Museum and the natural methods of group 

 mountings were also shown by extensive 

 exhibits. In vertebrate Palseontologj^ the 

 chief feature was three panels showing the 

 stages in the evolution of the horse; first, of 

 the modern skeleton in comparison with 

 that of Hyracoiherittm venticohtm, from the 

 Cope Collection recently acquired by the 

 Mu.seum ; second, a complete series of feet, 

 and third, a complete series of skulls. Two 

 newlj' discovered ancestral forms of Titano- 

 theres fi-om the Eocene were also sho^\^^, 

 displaying the first rudiments of the great 

 horns which characterize the latest survi- 

 ving members of this group. The most note- 

 worthy feature in invertebrate Paheontol- 

 ogj' was the collection shown by Messrs. 

 Van Ingen and Mattlu!w. of what appears 

 to be a sub-Olenellus fauna from the lower 

 Cambrian, in other words, the oldest fauna 

 thus far discovered. Under Geology, as ar- 

 ranged by Professor J. J. Stevenson, was 

 shown an extensive series of eruptive rock 

 from the pre-Cambrian volcanoes along the 



Atlantic coast, besides many results of 

 Prof. Kemp's field work. The Columbia 

 biological laboratorj' contributed to the 

 zoological exhibit a full series illustrating 

 the Golgi silver nitrate nerve-cell prepara- 

 tions, together with the results obtained 

 by the ' lithium-bicromate ' and ' forma- 

 lin ' modification introduced by Mr. Sti-ong, 

 exhibitor. Professor E. B. Wilson, dis- 

 played his new series of fertilization stages 

 of the Sea-Uchin, pro^^ng that the arch- 

 oplasm is entirely derived from the sper- 

 matozoon. All of these cytological ex- 

 hibits were accomj)anied bj' micro-photo- 

 graphs taken by Dr. Leaming. Dr. T. H. 

 Cheeseman had charge of the bacterial ex- 

 hibit, including priucipallj' a display of prep- 

 arations by the new formalin method, and 

 an illustration of the stages in the prepara- 

 tion of the anti-toxine treatment of diph- 

 theria. In Anatomy. Professor Huntington 

 displayed a unique series of 194 prepara- 

 tions, showing the comparative anatomy 

 of the caecum and vermiform appendix 

 throughout the vertebra ta. 



The Exhibit was open throughout the 

 afternoon to students, and throughout the 

 evening to guests of the Academy. The 

 admirable arrangements were largely due 

 to Professor Hallock, Chairman; Dr. Dean, 

 Secretary, and Professor Lee, Chau-man of 

 the Eeception Committee. The event fully 

 justified the large amount of time and care 

 which was given to its preparation, and in 

 tlie opinion of all those who were present 

 will prove a great stimulus to the various 

 branches of research now in progress in New 

 York. It has been informally decided to 

 renew these receptions fi-om year to year, 

 and to attempt to give them a more national 

 character by inviting exhibits from other 

 parts of the country. The galleries of the 

 Fine Arts Society, with unlimited wall space 

 for the exhibition of charts and diagrams, 

 with admirable means for electrical illumin- 

 ation for microscopic and other purposes,and
