— not merely of intoned vowels or selected syllables or formally 
enunciated phonographic records, but of actual spoken language 
in the setting of actual life. If, for instance, the phonodeik, 
either alone or in conjunction with the manometric flame, could 
be used to make as careful a study of the spoken language of 
many different persons, as it was used to make of intoned vowels, 
it would likely solve many important problems. Note further 
how many types of apparatus have been barely developed and 
demonstrated, but for lack of funds never applied to the solu- 
tion of urgent phonetic problems. Cases in point are the mano- 
metric apparatus of Nichols and Merritt and of J. G. Brown, 
Muenzinger’s compound lever apparatus and RosseCs syn- 
chronous recording and reproducing apparatus, all of which were 
noted above. When we consider that' language is the vehicle of 
all of human life and institutions and of all of our knowledge 
and study of the outside world, it may be reasonably contended 
that no other single phenomenon is a more important object of 
investigation. The scientific study of its different phases has 
already yielded writing, printing, telegraphy, the telephone, and 
the phonograph, besides making important contributions to 
psychology and physiology, as in the case of the doctrine of 
cerebral localizations which is a part of the basis of modern 
surgery. It is devoutly to be hoped that more nearly adequate 
provision may be made for the scientiflc study of language in all 
its phases. To which of our institutions of learning and research 
will fall the honor of leading in such a movement? 
III. NEW TYPES OF APPARATUS 
As to the development of new apparatus of the light-lever 
type, I would suggest two principles, to which we may provision- 
al y give the names of sonoscope and sonograph, the first in- 
volving the elimination of all physical levers but retaining a 
receiving horn andMiaphragm, the second eliminating all reso- 
nating and physically vibrating parts, and using a light-lever
