E. M. Kindle attended the Washington meeting of the International 
Geological Congress as a delegate of the Geological Survey and participated 
in the six-day Chesapeake Bay geological excursion that preceded it. 
Representative collections of the fossils of the Cretaceous and Tertiary 
formations of Maryland and Virginia were secured during this excursion 
for the reference collections of the Museum. 
Office Work 
During the early months of the 1933-34 year L. S. Russell prepared a 
model restoration of the horned dinosaur Chasmosaurus belli on a scale of 
fa natural size. The skeleton was modelled to scale, and upon this the 
muscles were reconstructed. A layer to represent integument was added 
and the skin pattern modelled on this. Plaster casts of this model are being 
prepared by C. E. Johnson. Several labels for vertebrate exhibits were pre- 
pared by L. S. Russell. 
In response to an invitation from the Central Canada Exhibition an 
exhibit was prepared and installed. A member of the division was present 
during the week of the exhibition to give any desired information. 
In the laboratory of vertebrate palaeontology seven skulls of the hooded, 
duck-billed dinosaurs were unpacked and partly prepared. Mr. Sternberg 
is at present confining his preparatory work and study to this group of 
dinosaurs. 
A. E. Wilson continued work on the catalogue of type fossils and further 
work on the synoptic exhibition cases. 
Museum Exhibits 
Four water colour paintings of Palaeozoic marine life by Mr. Lefebvre 
have been added to the systematic exhibits of fossils. Two tusks of the 
hairy mammoth were added to the exhibits. 
Considerable progress has been made in preparing an exhibit of marine 
and freshwater shells. 
To the series of exhibits in stratigraphic palaeontology a case of fossils 
has been added showing the succession of Palaeozoic faunas that characterize 
the Rocky Mountains section near the Canadian Pacific railway, the 
Pala?ozoic faunas of Jasper park, and the Devonian faunas of Mackenzie 
River valley. 
An exhibit has also been installed showing fossils preserved in amber, 
various concretions preserving fossils, and also a large variety of concretions 
that simulate fossils. 
Educational Work 
The divison has contributed to the educational work of the Museum 
by assembling during the winter two carefully prepared exhibits, which wuth 
other collections prepared by the biologists and anthropologists of the 
Museum, will be available as loans to Canadian educational institutions 
wishing to borrow them. One of these is a dinosaur exhibit confined chiefly 
to fossil material displaying the contrasted types of teeth that have been 
evolved to correspond with the different feeding habits of various kinds of
