562 PROCEEDINGS OF THE ACADEMY OF [1893. 



are the Rhoads collection of British Columbian birds, comprising 

 about 1,000 specimens, an important collection of birds and 

 mammals from southern California made by R. B. Herron, and the 

 Morelet collection of mollusca. 



Through the aid of friends of the Academy, Professor E. D. 

 Cope was also enabled, in company with Dr. A. P. Brown, to carry 

 on explorations in the fossil beds of Dakota and Kansas during the 

 summer. He brought back many valuable specimens which will 

 greatly enrich the department of vertebrate paleontology. These 

 specimens will be placed in the museum as soon as they can be prop- 

 erly mounted. 



As heretofore, the Academy's museum has furnished aid to many 

 students and specialists. Besides those who have consulted the 

 collections, specimens have been loaned during the year to Dr. C. 

 Hart Merriam, Dr. J. A. Allen, Dr. Harrison Allen, Mr. William 

 Brewster, Dr. L. Stejneger, Mr. G. D. Harris and Professor W. B. 

 Clarke. 



Certain collections which are not arranged in the museum 

 proper have, as in former years, been under the charge of special 

 conservators and to these the Curators desire to express their thanks 

 — to Mr. John H. Redfield, Conservator of the Herbarium; Mr. 

 W. W. JefFeries, Curator of the Vaux Collections, and Dr. Henry 

 Skinner, Conservator of the Entomological Section. Reports on the 

 condition of these collections will be found in the special reports from 

 the Sections. 



The thanks of the Curators are also due to Mr. W. W. Jefleries 

 for his valuable assistance in the labeling and arranging of the 

 Carpenter collection of minerals, to Mr. Clarence B. Moore, for the 

 careful arrangement and labeling of his archaeological collection, 

 and to Messrs. Woolman, Schultz and Boyer for valuable assistance 

 in cataloguing the collections of diatoms. 



Messrs. H. G. Ives, J. E. Richardson and H. Y. Pennell, stud- 

 ents on the Jessup Fund, have rendered important aid during the 

 year in the departments of mineralogy and ornithology.
