His splendid collection of footprints was purchased last 

 year by Councillor C. Sydney Jones and presented to the 

 Liverpool Public Museum ; his albums of photographs were 

 presented to the Liverpool Geological Society, and his other 

 geological material has been acquired by the Geological Depart- 

 ment of the University. 



Mr. Beasley was imbued with the spirit of the fine old 

 British amateur geologists. Although active commercial duties 

 left him scanty leisure for geology, he pursued the Science with 

 unabated vigour until illness compelled him to relinquish the 

 work. His kindly and helpful disposition endeared him to his 

 friends. 



On May 28th, 1920, at the early age of 42, Leonard 

 Donc aster, Derby Professor of Zoology in the University of 

 Liverpool, passed away. Perhaps the most brilliant of the 

 younger school of British zoologists, he was early attracted to 

 the problems of variation and heredity, to which he applied 

 the exact methods of cytological research. A believer in the 

 theory of Mendelism, he was led on to problems relating to 

 the determination of sex, his work upon which constitutes a 

 milestone in the progress of biology. His books upon " The 

 Determination of Sex " and " The Study of Cytology " remain 

 a monument to his memory as well as an indication of what 

 we have lost by his early death. 



We knew him as a colleague for barely a short session, 

 but his humanity, charm, and uprightness commanded our 

 affection and respect. To use Professor Herdman's words, 

 his death was nothing less than a calamity to the University 

 of Liverpool and, one would add, to the cause of Science.
