REPORT ON THE DEPARTMENT OF GEOLOGY 

 FOR THE YEAR 1902-3. 



By GEORC4E p. Merrill, 

 Head Curator. 



The year that has just closed compares very favorably with those 

 immediately preceding-, both as to the number and value of the acces- 

 sions. The Department is to be particularly congratulated on acquiring 

 the Rominger and Sherwood collections of vertebrate and invertebrate 

 fossils; another large portion of the Ulrich collection, and three entire 

 meteorites from Kentucky and North Carolina, as noted below. The 

 tine example of the Shergott3% India, meteorite, secured through 

 the courtesy of Dr. T. H. Holland, and a fragment of the celebrated 

 diamond-bearing meteorite from Novo Urei, Russia, are also worthy of 

 mention.

 purchase, or exchange.
