THE AMERICAN MUSEUM JOURNAL 



The obser\'ation beehive, which was installed in one of the 

 windows of the Hall of Entomology last spring, has proven a 

 constant source of interest to the visitors to the Museum. The 

 bees, some 10,000 in number, that make this hive their home, have 

 been so industrious that the hive has been nearly doubled in size 

 since it was first installed. The hive contains not less than 

 seventy-five pounds of honey and is a practical illustration of 

 what might be accomplished in the way of bee-keeping by any 

 person in the city, at any rate by one living near the parks. 



Mr. Barnum Brown, of the Department of Vertebrate 

 Palaeontology, who has been carr^dng on exploring work in east- 

 ern Wyoming during the past season, reports that he has found 

 two Plesiosaur skulls which are in the best and most nearly com- 

 plete condition of any known to be in existence. With one of 

 the skulls was associated most of the skeleton belonging to the 

 individual. These finds will enable the department to place on 

 exhibition a practically complete skeleton of this rare animal. 

 Mr. Brown furthermore reports the finding of several more or 

 less nearly complete skeletons of Mosasaurs. 



Mr. J. H. Batty, who is conducting an expedition in Mexico 

 for the Department of Mammalogy and Ornithology, reports 

 satisfactory progress and has forwarded to the Museum a large 

 quantity of material supplementing the extensive collection 

 already in the building. The boxes comprising Mr. Batty's 

 first shipment of the present expedition contained 274 specimens 

 of mammals, 518 specimens of birds, about 400 specimens of 

 serpents and reptiles and 64 specimens of invertebrates, together 

 with the accessories needed for mounting some of the forms as 

 groups. An important feature of the expedition is the number 

 of negatives which has been taken. 



Mr. George H. Sherwood of the Department of Inverte- 

 brate Zoology spent about a fortnight in August at Southport, 

 Maine, collecting marine invertebrates for the Museum series 

 and for the work being carried on by the Museum in co-operation 

 with the public schools. Among the material resulting from 

 this expedition may be mentioned many beautiful hydroids, a
