1808.1 SENATE— No. 218. 9 



J 



It gives me great pleasure, also, to state that I have been able 

 to induce Dr. Hagen, of Konigsberg, to come over to Cambridge 

 and assume the arrangement of the department of Entomology. 

 The loss of Mr. Uhler, who, to my great regret, was called 

 away from us by his appointment as Superintendent of the 

 library of the Peabody Institute, at Baltimore, left a great 

 hiatus in our organization. This blank is now filled, and the 

 high position which Dr. Hagen holds among Entomologists 

 makes his presence among us not only of immense practical 

 service to the Museum, but an honor also to the scientific 

 character of the institution. Dr. Hagen has already presented 

 a general plan for the arrangement of the collection intrusted 

 to his care, which I shall submit to you as soon as its execution 

 has been so far carried out as to give material evidence of its 

 excellence. 



Shortly after the departure of Mr. Uhler, the Museum 

 sustained another great loss in the death of my old friend, Mr. 

 Burkhardt, who, for more than thirty years, had worked by my 

 side faithfully, drawing the specimens I was investigating. 

 His place is now occupied by Mr. Paul «Roetter, from whose 

 service I expect valuable results in the illustration of the 

 original researches carried on at the Museum. 



There are also some other names absent from the annual 

 record of scientific work accomplished at the Museum, which 

 are usually associated with it. Private considerations have 

 called away my son, Alexander Agassiz, but before the year is 

 over he expects to resume his post. Mr. Shaler also has been 

 travelling in Europe for his health, while at the same time 

 continuing his studies with reference to the Museum, and I 

 trust we shall soon have his valuable services again as a perma- 

 nent associate of the institution. Mr. St.-John has been 

 appointed assistant to the State geological survey of Iowa, a 

 service in which he is likely to be engaged for a long time, 

 and for which his mature studies here had well prepared him. 



Mr. Allen, who had been compelled by ill-health to abandon 

 his work at the Museum after his return from Brazil, has lately 

 resumed his place, and is now engaged upon the arrangement 

 of the Ornithological collection. I have also secured, recently, 

 the services of the Rev. Mr. Perry, in the systematic arrange- 

 ment of the Tertiary fossils.
