212 HISTORY OF PASADENA. 



our museum as soon as it is finished. We have an Academy of Sciences 

 ready to arrange and utilize them." 



The Academy of Sciences referred to was organized in January, 1886, at 

 the residence of Hon. Delos Arnold, on Kansas [now Green] street between 

 Fair Oaks and Raymond Avenues. Mr. Arnold was elected president of the 

 society. Other members were : Prof. C. F. Holder, Dr. Wm. F. Channing, 

 Dr. N. D. Van Slyck, Mrs. Jeanne C. Carr, Maj. H. N. Rust, Frank J. 

 PoUey, Esq., J. R. Greer, C. T. Hopkins, and others. The "museum" 

 mentioned by Mr. Hopkins was never provided for in the Library building. 

 The Academy of Sciences, however, has never disbanded, but holds a nomi- 

 nal existence yet, although in a state of quiescent dormancy. And the 

 ' ' collections ' ' mentioned have become historic, giving prestige and fame to 

 Pasadena, as follows : 



Mineralogy Collection. — This belongs to Hon. T. P. Lukens, and 

 comprises specimens of every sort of mineral that has any commercial value, 

 ever found in L,os Angeles County, besides others from all over California 

 and the other mineral bearing states of our own country, and many other 

 parts of the world. There are also specimens of fossil wood found in exca- 

 vations at Los Angeles city, and from other places ; and fossil fish and leaves 

 from our local " fossil hill," down the adobe road toward lyos Angeles. Mr. 

 Lukens had a complete catalogue of his collection made in June, 1895. 



Geology Collection. — This was Dr. Ezra Carr's, which amounted to 

 some tons weight and had lain in their shipping boxes, unshelved, ever 

 since they were brought to Pasadena in 1880. In 1894 this valuable accum- 

 ulation of specimen fossils, minerals and rock types was donated to Throop 

 Polytechnic Institute. 



CoNCHOLOGY Collection, — Hon. Delos Arnold has the largest and 

 finest accumulation of scientific material in this line of an}^ man in the State, 

 I suppose — and all systematically arranged and classified — a total of about 

 25,000 specimens. Among these are some 1,500 different living species or 

 varieties of moUusca, about 400 species of which are found on the Pacific 

 coast, and at least half of these occur in Los Angeles county. More varie- 

 ties are found at San Pedro Bay and vicinity than at any other one point 

 from Alaska to San Diego. Also about 300 species of fossil shells have been 

 found at San Pedro and Deadman's Island. In Mr. Arnold's collection as a 

 whole, there are specimens representative of every age in the geological 

 scale, from the lower Silurian up to the living present. And some 25 or 30 

 specimens from this Pasadena collection were illustrated in Vol. 8, of the 

 State Geological Reports of Illinois, published in July, 1890 — one of them 

 being Adinocrmus Arnoldii, which Mr. Arnold himself discovered in a quarry 

 near Marshalltown, Iowa ; it was named by the professional experts, and 

 pronounced the only specimen of its species known in the world. These 

 illustrations were borrowed and used in ' ' North American Geology and
