FREEFAGE 


THIS compilation was undertaken as it was thought desirable 
that there should be available to students and scientists, an 
up-to-date work somewhat on the lines of Stormonth’s MZanual 
of Scientific Terms (1879, republished 1903). It contains 
definitions of about ten thousand terms, including several 
hundred lately coined expressions, many of which have not 
hitherto appeared in a dictionary. The work is expected to 
supply a want felt by many students and other readers of 
the Biological Sciences, as the usual handy-sized dictionary 
contains comparatively few purely scientific terms. The sub- 
jects selected for treatment are Biology and its allies, Anatomy, 
Botany, Zoology, Embryology, Cytology, Physiology; and 
some terms in Bacteriology and Palaeontology are included, 

In a first edition of a book of this kind, errors of omission are 
inevitable, as few people have convenient access to each text- 
book and treatise, even in one subject, as it makes its appearance 
Suggestions for additions will be welcomed and noted for future 
use, and should be accompanied by the name of the work in 
which the original definition is to be found; derivation offers 
no difficulty as a rule, but pronunciation might be indicated by 
coiners of entirely new terms. 

In the etymological section, Greek words have been trans- 
literated, as science and medical students are seldom acquainted 
with that language, and on the advice of an authority on 
Greek, the transliteration of certain combinations of letters 
represents the sound rather than the exact letters of the 
original; hence the frequent occurrence of such words as 
brangchia, hydor, etc. 

This work was begun by Mr J. H. Kenneth, who compiled 
most of the primary lists from which the whole has been 
elaborated. Mr Kenneth had completed upwards of three

hundred terms when ill-health prevented his continuing the 
work, and it was handed over to the present authors. 

We have to acknowledge our indebtedness to Professor 
J. H. Ashworth of Edinburgh University, who has very kindly 
read over the manuscript and given us some suggestions for 
additions.

NOTE AS TO PRONUNCIATION 


Ir has seemed expedient in many cases to give alternatives, as different 
centres of learning have different types of pronunciation ; again, as it is 
usage which determines correct pronunciation, and the terms are not 
everyday words, it will be long before a term which lends itself equally 
well to two methods will be fixed down to one. 

As to many anatomical and other purely Latin terms, students will 
probably follow the type of pronunciation, English or Continental, 
learned at school; in the latter case, the second alternative or some 
modification of it will be employed. Those who can readily pronounce 
ch as in loch, and who have so learned to pronounce the combination 
in Greek, will naturally introduce that sound into such words as 
branchial, brachyenemic ; although the & sound has been adopted in 
this as in other dictionaries, the other is not to be regarded as 
incorrect. 

The sound-symbols have been made as simple as possible, only the 
broader differences of vowel-sounds having been included. A general 
indication of pronunciation, rather than a critically exact reproduction, 
is what is wanted for the average reader of scientific works. 

In the case of words which have not previously appeared in a 
dictionary, and whose pronunciation is not clearly indicated by 
etymological or other rules, it remains for the coiner to indicate his 
preference.
