clinics, a new testing and experimenting 

 laboratory in civil engineering, new ma- 

 chine shops in mechanical engineering, and 

 an entirely new establishment for the de- 

 partment of chemistry, where the great in- 

 crease in the number of students taking the 

 work has created serious embarrassment 

 even necessitating the exclusion from the 

 already overcrowded laboratory of under- 

 graduates in whose courses chemistry is a 

 prescribed or elective subject. A new 

 chemical laboratory entirely adequate for 

 the purpose would, as President Schurman 

 estimates, cost from $300,000 to $400,000. 



THE DELOS ARNOLD COLLECTIONS OF 

 NATURAL HISTORY SPECIMENS 



Hon. Delos Arnold, of Pasadena, has pre- 

 sented to the department of geology of Stan- 

 ford University his grtat collection of fossils, 

 shells, corals, minerals, ethnologic materials, 

 etc. This collection is a gift to the university 

 on the condition that it be kept intact, and 

 that it be properly cared for, labeled and 

 exhibited. It represents the work of a life- 

 time by an enthusiastic student and collector, 

 and is one of the finest private collections of 

 fossils in the country. It is especially valu- 

 able on account of the large amount of recent 

 and Tertiary material collected on the west 

 coast of North America. Por the use of stu- 

 dents of the geology of California and the 

 west coast generally, it is without an equal. 



The collection was begun by Mr. Arnold in 

 1860 when he lived in the state of Iowa, and 

 besides the constant work done upon it by 

 him, it has received many acquisitions up to 

 1908, and it is stipulated by the donor that 

 still further additions may be made to it in 

 the future. Most of the minerals were col- 

 lected in Colorado in the seventies and in 

 Arizona in the eighties. 



The collection of recent marine shells so 

 necessary in the study of Tertiary geology is 

 one of the finest in this part of the country, 

 and it embraces a large amount of material 

 collected on the Atlantic coast from Maine 



to the West Indies. It includes most of the 

 co mm on forms both of shells and corals and 

 a large number of the rarer ones collected 

 by Mr. Arnold at Jacksonville, Key West, 

 St. Augustine and New Orleans. Of the west 

 coast materials, it embraces collections made 

 by Mr. Arnold and his son Dr. Ealph Arnold 

 almost continually all the way from Puget 

 Sound to Panama, and includes both the 

 littoral species and the deeper water forms 

 obtained by dredging. There are also a good 

 many shells obtained by exchange and pur- 

 chase from Europe and other parts of the 

 world, and especially from the Mediterranean 

 Sea, from the coasts of France, and from the 

 Hawaiian Islands. A representative col- 

 lection of fresh-water shells from various 

 parts of the United States is also included in 

 the materials. 



The fossils, however, form the most im- 

 portant part of the collection. These em- 

 brace Paleozoic, Mesozoic, Tertiary and 

 Pleistocene forms. The paleozoic materials 

 include one of the best collections ever made 

 from the famous crinoid-bearing Kinderhook 

 beds (Carboniferous) at Le Grand, Iowa. 

 Many of these fine specimens are types, and 

 are figured in Wachsmuth and Springer's 

 monograph on the crinoids. Of especial in- 

 terest in connection with the collection of 

 fossil crinoids is a beautiful specimen of a 

 living crinoid from the China Sea. 



The Mesozoic materials of the collection 

 come from different parts of North America, 

 notably from California, and the Dakotas, and 

 from Europe. 



The collection of Tertiary and Pleistocene 

 fossils is among the best of the kind in exist- 

 ence, and, in many respects, it is unique. 

 It includes a number of types and a large 

 number of specimens that have been figured in 

 publications upon the Tertiary and Pleistocene 

 of the Pacific coast, notably in the papers 

 published by Dr. Ealph Arnold, the dis- 

 tinguished son of the donor. Getting to- 

 gether this particular part of the collection 

 has occupied Mr. Arnold's time for twenty- 

 two years. At San Pedro, one of the richest 

 and most important localities where collecting
