LISTER I THE STUDY OF MYCETOZOA IN BRITAIN. 2ig 
Mv father wrote also a Guide to the British Species of Mycetozoa 
to explain the table-case of specimens exhibited in the botanical 
gallery of the British Museum. This little book, which can 
be obtained for the sum of three pence, contains a sketch of 
the life history and descriptions of all the British species. It is 
illustrated by wood-cuts showing the characters of each genus. 
The stimulus which the publication of the Catalogue 
■of the Mycetozoa and of the Guide gave to the study of 
these creatures led to a rich increase of correspondents living 
in many parts of the world. Many new species were discovered 
and a wealth of information with regard to geographical dis¬ 
tribution was obtained. A number of articles summing up 
new facts and observations were published by my father, and 
materials stored for a second edition of the Monograph —an 
edition which he did not live to bring out. 
It was my father’s delight to share his ‘ hobby,’ as he called 
it, with others. Unstinted help was gladly given to all who 
asked for it, whether by identifying or in giving specimens, or 
by carefully written letters of instructions. 
To quote from my brother’s Obituary Memoir of my father, 
written for the Royal Society, “ His was no dry and lifeless 
exposition ; he stood rather as one who had ascended the Mount 
of Vision and whose high privilege and urgent duty it was 
to reveal what had been vouchsafed to his view. This was, 
in fact, his attitude of mind to all the phenomena of nature, 
whether the ways of beast or bird, the structure of plants, 
geological or physical phenomena, or the movement of the 
heavenly bodies. It was all a revelation of the mystery of 
life or of the environment of living things on the earth and 
in the universe. When moved to speak of these things, he 
would cast aside a shyness which had clung to him from his 
boyhood and discourse with a force and eloquence which carried 
conviction to the hearers and enlisted their sympathies in the 
cause.” 
My father was an original member of the Essex Field Cdub. 
He did not attend many of its meetings, partly from his 
living for some months every year at Lyme Regis, but he 
always had great sympathy with its objects and ideals. 
Of my brother J. J. Lister’s work on Mycetozoa, I will 
only say that all his observations, such as those on the division
