PREFACE. 

THE increasingly numerous class of learners and junior students in 
our higher class schools and colleges, as well as of general readers, 
experience the want of a ' Manual of Scientific Terms ' specially suited 
for the particular stage of their studies. The present work is an 
attempt to furnish such Lists of Terms in Botany, Natural History, 
Chemistry, Anatomy, Medicine, and Veterinary Science, as may be 
met with in the student's ordinary text-books, and in the current 
literature of the day. No attempt has been made to supply an 
exhaustive vocabulary. The selected words have been taken from the 
more popular text-books ; and the definitions are very generally given 
in the language employed in them, though often simplified. The 
Author feels assured that the special end in view, in the preparation of 
the present work, has been best served by making this legitimate use 
of such text-books ; for the language and phraseology employed in his 
text-books must become familiar to the student in the course of his 
studies. 

The general terms in Botany will be found a pretty exhaustive list. 
All the names of Orders, and generally Sub- orders, as found in 
Balfour's Manual of Botany r , have been inserted. Only, however, 
such names of genera and species are given as have some noteworthy 
particulars or qualities affirmed of them. The list of Latin Anatomical 
terms will be found a very full one ; but only such compound terms 
are given as are deemed most useful, inasmuch as the Latin compounds 
are now very often laid aside, and their English equivalents employed 
instead. The terms in Natural History, Chemistry, Medicine, 
and Veterinary Science, will be found in sufficient numbers to meet 
ordinary requirements. 

Each term is followed by its re-spelling in simple phonetic characters, 
and accented, while the syllabication employed is that laid down in 
the Author's Handy English Word-Book and Complete Dictionary 
Appendix. 1 - By using these methods, the pronunciation has been indic- 
ated with very great precision. A system of re-spellings with the view of 
indicating the correct pronunciation of scientific terms was much needed, 
for the pronunciation of many of them sadly puzzled most persons, and

viii PREFACE. 

even scientific men were frequently not agreed as to the correct pronuncia- 
tion of many terms which they were constantly using ; indeed, they 
were not unseldom inconsistent with themselves in the pronunciation of 
many scientific terms. The endeavour is here made, and it is hoped 
not unsuccessfully, to settle the pronunciation of terms in regard to 
which there has hitherto been no certain agreement. Where the 
pronunciation of a term has been fixed by usage, such of course has 
been retained. In every case, the analogy of the English language, 
and the etymology of the term, has been considered in fixing its 
pronunciation. The student must particularly remember that the 
symbols ( w ) here employed to indicate English pronunciation 
regard the quality of the vowel-sounds only, and not quantity, as in 
Latin and Greek. Hence it often happens that the root-words, or 
Latin words within the brackets, may have such a symbol as (J) 9 
while the corresponding syllable in the Latin word, re-spelt for pronun- 
ciation, may have the symbol (-), and vice versa. 

The student or learner should, in the case of a difficult or uncertain 
word, enunciate aloud each syllable of the re-spelling, distinctly and 
firmly, pronouncing each syllable and word repeatedly, always taking 
care to place a halt or stress on the accents marked thus (' or '). By 
such practice, the pronunciation of the terms will be well and correctly 
done ; and repetition, first slowly, and then more rapidly, will tend to 
fix their pronunciation in the memory. The re-spellings is an important 
feature in this work, and its importance will readily be seen and 
understood. The table of sound symbols on page x, should be care- 
fully studied. 

The root-words or etymologies, and Latin words with literal meanings 
and their quantities, are placed within brackets. It is of great import- 
ance to exhibit the primary meanings of the terms by means of root- 
words, and the simpler forms of Latin terms. A root- word not only 
exhibits the origin of a particular term, but very frequently supplies 
a key to the primary meanings of a large number of other related 
terms. In the case of specific and anatomical terms, the meaning of 
each Latin word is given clearly and literally. 

In the study of Botany, Anatomy, and Geology, specific names are 
apt to be misunderstood. At any rate, to the learner and young 
student, they are often mysterious and puzzling. Accordingly, a con- 
siderable list of the second names of the binomials, used as specific 
names, has been given by way of an Appendix, beginning on page 448. 
In order to smooth the way to many not over familiar with Latin, or 
entirely ignorant of that language, the list of specific names has been 
prefaced by a short introduction ; and a considerable number of 
examples of Latin nouns and adjectives have been declined, marked 
for pronunciation, and defined. This will be found no less useful 
to the student in the study of anatomical terms. 



PREFACE. IX 

Following the specific names, there will be found a pretty full list of 
prefixes, including those used in connection with scientific terms. The 
list of postfixes contains only the common terminations of scientific 
terms. These are not only explained, but also illustrated by examples. 
In the examples the roots are printed in black letters, and the prefixes 
and postfixes in italics, A list of abbreviations in use by medical 
practitioners, with their unabbreviated forms and meanings, concludes 
the work. 

Students or learners are recommended to use the present work before 
commencing their special studies, or, at least, in the earlier stages of 
them, as a daily lesson-book. Let a certain portion be accurately com- 
mitted to memory daily, or frequently, and the very great advantage of 
such a course will be seen and felt on its accomplishment, for by so 
doing students will attain a competent knowledge of the spellings of 
the terms, their pronunciation, their root-words, and their definitions. 
Equipped with this knowledge, they will be able to follow the lectures 
and instructions of their teachers and professors both with freshness 
and intelligence. In short, by a little hard work to begin with, their 
after-studies will become very much more pleasant and profitable. 

Though great care has been exercised in the preparation of the work, 
it is scarcely to be expected that it will be free from error. It is 
hoped, however, that errors will be unimportant, and few in number. 

The Author has here to acknowledge the deep obligation under 
which he lies to G. W. Balfour, Esq., M.D., E.R.C. P., of Edinburgh, 
and to Alexander Morison, Esq., M.D., of Canonbury, London, for many 
excellent suggestions. The whole proof sheets were carefully read by 
Dr. Balfour, and a similar service was rendered by Dr. Morison on the 
MS. Of course, the suggestions and corrections made by these gentlemen 
chiefly regarded terms in those departments of science with which they 
were most conversant. The Author also gladly acknowledges similar 
favours from other friends. While thus gratefully acknowledging his 
obligation to these gentlemen, and other friends, it must be distinctly 
understood that the Author is alone responsible for any deficiencies 
which may be found in the work. 

The Author of this compilation now submits his work to the 
judgment of professional men, and the general public, and he will be 
glad to learn that their judgment in regard to the objects of the work, 
as well as the manner of its execution, is a: favourable one.
