We hail the advent of Volapuk from voda of 
the world; and /zz, language, the new scien- 
tific international language. By means of this 
most useful medium we may, in the future, | 
talk or write to our brothers in science of | 
any nationality without fear of the confusion | 
born at Babel. We quote from 7he Educational | 
eview of Saint John, N. B.: “It is formed 
on the general model of the Aryan family of 
languages. Its material is largely taken from 
the English, but itsstructure, noun-declension 
and verb-conjugation is rather un-English, as | 
are two or three of its vowels. It is far easier | 
learn than any existing language, and has | 
already made rapid progress in twenty or thirty 
European or Asiatic languages. The text-book 
‘Seret’s Grammar with Vocabulary of Vola- 
puk,’ 420 pages, published in Glasgow, by 
Thomas Murray & Son, and in London, by 
Whittaker & Co, At a Congress of Volapuk 
scholars in Munich this year, a Volapuk Acade- 
my was formed. The next meeting of the Con- 
gress is in Paris, 1889.” 
Two new and valued contributors have 
been added to our list since last issue, and we 
trust the articles by Mr, Berlfm H. Wright, of 
Lake Helen, Florida, and Mr. Theo. D. A. 
Cockerell, of West Cliff, Colorado, will meet 
with the approval which the painstaking labors 
of the writers in the field of Conchology so 
richly deserve 
AN absurd error crept into the article “On a 
New Floridian Natica,” by Mr. Charles T. 
Simpson, in our last number. The types gave 
the size of the shell, Vatica Lordiana, Simpson, 
as “length, 40 inches, diameter, 30 inches,” 
whereas, the dimensions should be /ezgth, .4o 
inches, diameter, .30 inches. The shell was 
named in honor of Mr. John Ford, of Philada. 
WE make a special request of our young 
readers to forward us any original matter upon 
Conchology for inspection previous to insertion 
in our “ Young Collectors’ Corner,” which they 
must look upon as open to all young readers. 
Cultivate the habit of describing shells as voz 
find them, and, take our word for it, it is not 
at all impossible that you may find the solution 
to many knotty problems which have puzzled 
older heads. 
WHEN we send you a sample copy of THE 
CONCHOLOGISTS’. EXCHANGE, we help you to 
subscribe by meeting you half way. The rest 
is an easy business transaction, and consists in 
forwarding 50 cents for the certainty of an early 
and sure profit.
