Museum in the fall the first presentation 

 of the zoological results of his recent expedi- 

 tion to South America. 



Two expeditions from the department of 

 vertebrate palaeontology will be sent out this 

 summer in search of fossils. The first expedi- 

 tion in charge of Mr. Barnum Brown, assisted 

 by Mr. P. C. Kaisen. will confine its operations 

 to the Red Deer River of Alberta, Canada, 

 where it will endeavor to collect Cretaceous 

 dinosaurs, and the second in charge of Mr. 

 Albert Thomson will go to the big quarry at 

 Agate, Nebraska, to secure additional Moro- 

 pus skeletons. 



Mr. John A. Grossbeck, a patron of the 

 Museum and a member of the department 

 of invertebrate zoology, died in Barbados 

 on April 8. Although Mr. Grossbeck was 

 taken ill more than a year ago, his health 

 seemed to be partially recovered, and in order 

 to regain his strength he was touring the 

 Caribbean region with his brother when he 

 died suddenly during a change of boats. 



Mr. Grossbeck came to the Museum about 

 four years ago, having previously been con- 

 nected with the New Jersey State Experiment 

 Station. While in that institution he made 

 valuable discoveries concerning a wide range 



214 



of injurious insects but especially concerning 

 the life history of mosquitoes. His chief 

 scientific interest however was in the Geome- 

 tridse — • the family of moths whose young are 

 the "measuring worms." On coming to the 

 Museum Mr. Grossbeck gave to it his valua- 

 ble collection of this group as well as his gen- 

 eral collection of local insects. In recognition 

 of his generosity he was made a patron. Mr. 

 Grossbeck devoted himself to the work on in- 

 sects with untiring zeal and by reason of his 

 broad entomological training was able to 

 further the work in all of its branches. He 

 had already made an international reputation 

 in entomology and it will be exceedingly diffi- 

 cult for the Museum to find a successor who 

 will combine Mr. Grossbeck's wiUingness to 

 serve with an equal entomological knowl- 

 edge. 



The Museum wishes to express its sincere 

 sympathy to the bereaved families of two of 

 its workers, William A. Dolan and Christian 

 Hundertpfund of the mechanical staff, who 

 had served the institution faithfully for 

 thirteen and twelve years respectively. 



The publicity committee of the Museum, 

 created during the winter, has been endeavor- 

 ing to acquaint the people in New York City
