PHILADELPHIA PREFACE TO THE EIGHTH EDITION. 
The Eighth Edition of this book has been carefully 
revised, and a large amount of new matter has been added. 
A vast number of new terms have appeared in surgery, 
pathology, clinical medicine, laboratory methods, chem- 
istry, serology, dentistry, veterinary medicine, and 
nursing. The new terms in these departments have been 
added, with the result that the Eighth Edition defines 
several hundredTmore words than the previous one. 
The Seventh Edition of this book had an extremely 
large sale, and the editor has been encouraged to make 
the Eighth Edition more complete than ever before. PREFACE. 
This small volume is the outcome of a need for a pocket 
dictionary which, though handy in size, should be so full 
and complete as to supply the wants of the practising 
physician no less than those of the student of medicine 
It is not the editor's intention to attempt to take the 
place of the larger dictionaries indispensable to a thorough 
understanding of the language of medicine, but he has 
striven to develop the possibilities of the pocket lexicon 
to a degree not heretofore attained. 
The chief aim has been to make the selection of words 
as complete as possible. To this end the larger diction- 
aries have been freely used, and a systematic gleaning has 
been made through the latest medical literature, so that 
the vocabulary may be said to be strictly up to date. Of 
necessity the definitions of terms are brief, but the en- 
deavor has been to make them clear, adequate, and to the 
point. 
The order of arrangement of matter is strictly alpha- 
betical. In cases of a phrase, consisting of a noun and 
qualifying adjective, the definition will usually be found 
under the noun, under which all the phrases containing 
that noun have been grouped. 
Besides the ordinary dictionary words it has seemed 
desirable to insert a considerable amount of matter in 
tabular form. This matter, it is believed, will prove of 
value to students for memorizing in preparing for exam- 
inations, besides serving to group correlated facts in a 
convenient form for quick consultation. INDEX TO THE TABLES

Ehr'Itch's solution. Basic anilin dye in anilin oil and 
water. E.'s 600. See Salvarsan. E.'s side-chain or 
lateral-chain theory, a theory regarding immunity and 
cytolysis, according to which the protoplasm of the body 
cells contains molecules, consisting of a stable central group, 
to which are attached less stable "lateral chains" of atoms. 
The chemical transformations in the protoplasm are carried 
on by these lateral chains (receptors'). The lateral chains con- 
tain a group (haptophore group) which is capable of uniting with 
similar groups (haptophore groups') in toxins, bacterial cells, 
and foreign cells. As the lateral chains are seized upon by the 
foreign cells, the stable central group is stimulated to produce 
new lateral chains (receptors) which are thrown off into the body- 
juices. These side chains constitute intermediary bodies. The 
Intermediary bodies (called also cep tor, haptine, immune body, 
sensitizer, fixative, preparative, and desmon) are designated, ac- 
cording to their nature, as uniceptors and amboceptors. The uni- 
ceptors, represented by the antitoxins, produce their effect by 
seizing the toxin by means of its haptophore group. The ambo- 
ceptors, represented by the cytolysins and bacteriolysins, have 
two affinities, one for the invading foreign cells, and one for a 
body called the complement, end-body, or addiment, which exists 
normally in the body-juices. The complement, when united with 
the oacteria or foreign cells by the amboceptor, is capable of 
causing solution of the bacteria or cells by means of a toxophore 
or zymotoxic group.

IN BOTH APOTHECARIES' AND METRIC SYSTEMS. 
The following doses are intended for adults. The dose for a child may be obtained approximately by Young's rule: Divide the 
age by the age plus 12, which will give the fraction of the adult dose to be used for the child. Thus, for a child of four years, 
4 
--- = i, and the dose is J that for an adult. 
4+12 *' 
Narcotics should be given in only one-half this proportion, while cathartics may be employed in two or three times this proportion. 
For hypodermic use the dose should be one-half of that by the mouth; by the rectum, five-fourths of the same. 
In the following table gr. = grains, dr. = drams, m. = minims, oz. = ounces. The doses in the metric system are either grams or
