I, Gilbert Logaa Houser, was born on an Tos-d fam in 136*?. 

 My preparatory training /ras given by several academies ani col- 

 leges not far from home, ^-ntering the University of Iowa, 1 

 pursued an undergraduate course in that institution for four 

 years, receiving the degree Bachelor of Science in 1891. A 

 year was subsequently spent in graduate study at the University 

 of Iowa, leading to the degree Master of Science, 1B92. My 

 graduate studies have since been continued in connection with 

 the University of Chicago and the Johns Hopkins University. 



My earlier investigations were chiefly in the fields of 

 geology and paleontology. The dissertation for the Master's 

 degree was a critical study of the "Genera of Paleozoic Corals 

 of the Order Madreporaria". Later, the Iowa Geological Survey 

 comrnissioned me to examine certain building-stones and lime- 

 burning rocks of eastern Towa; my report on this subject is 

 published in the Report of the Iowa Geological Survey, Vol.1. 

 Receiving an appointment as Instructor of Biology in the Uni- 

 versity of Iowa, my studies have since flowed entirely in biolog- 

 ical channels.
