date as a student and investigator, together with a list of such 

 original papers as may have been published by him. The appli- 

 cation should be also accompanied by a statement of the character 

 of the investigation which the candidate desires to pursue, and 

 the dates between which he wishes to occupy the table. 



Appointments will be made by the secretary of the Smithsonian 

 for a specific period, and, in the considpration of the claims of the 

 candidates, the Secretary will probably avail himself of the coun- 

 sel of an advisory committee of four, representins; the National 

 Academy of Sciences, the Society of American Naturalists, the 

 American Morphological Society, and the Association of Ameri- 

 can Anatomists. 



Persons who may occupy the Smithsonian table are expected to 

 make a report at the end of their term of occupation, or every 

 three months in case of long residence at the station. It is ex- 

 pected that due credit will be given to the Smithsonian Institution 

 in any publication resulting from studies carried on at its table, 

 and the "Smithsonian Contributions to Knowledge" will proba- 

 bly be available for the publication of at least a part of the papers 

 resulting from the Naples investigations. 



All correspondence should he addressed to S. P. Langley, Secre- 

 tary of the Smithsonian Institution, Washington, D.C.

S. P. Langley, Professeur Dr Anton Dohrn, 



Secretary of the Directeur de la Station Zo61o- 



Smithsonian Institution. gique de Naples. 



In conclusion, I wish to express my obligations to the signers 

 of the petition for their prompt and hearty support in this matter, 

 which is of great interest to us all. 



The Smithsonian Institution has now placed a table at our dis- 

 posal, and in so doing has rendered to the professional biologists 

 of the country a service which should be appreciated by all, and 

 which will be especially appreciated by those of us who, on ac- 

 count of the non-existence of an American table for many years 

 prior to the establishment of the Davis table, have either been 

 debarred from the Naples Station or have worked there only at 

 the courtesy of foreign institutions or by personal favor of Pro- 

 fessor Dobrn. Let us now show our appreciation of Professor 

 Langley's action by seeing that the table is occupied the entire 

 time. I would respectfully suggest that those conteuiplating 

 making application for the use of the table should do so at as 

 early a date as possible, so that ample time will be given for cor- 

 respondence and for arranging a proper distribution of the table 

 so that all worthy applicants may be given an opportunity to 

 spend a few months at the station. 



Respectfully submitted, 



C. W. Stiles. 



ASSOCIATION OF COLORS WITH SOUNDS. 



BT B. F. UNDERWOOD, CHICAGO, rLL. 



A BLOW on the head often gives rise to luminous sensations 

 (for luminousness is a sensation and not, as is popularly supposed, 

 a thing per se) and, under the influence of the shock, the person 

 seems to see a multitude of sparks. Describing the effect of a 

 fall on the ice, boys say it made them "see stars." Frequently 

 there is great variety and brilliancy of colors tbus seen. Vibra- 

 tions which, affecting the auditory nerve, produce the sensation 

 of sound, in some cases have the power of causing the sensation 

 of luminousness. Indeed, there are persons who, whenever they 

 hear a sound, also perceive a color, one sound corresponding 

 with red, another with blue, another with green, etc. Dr. Nuss- 

 baumer, of Vienna, relates that when a child, in playing one 

 day with his brother, he struck a fork against a glass to hear the 

 ringing, and while he heard the sound, he discerned colors. He 

 says that when he stopped his ears, he could tell by the colors 

 how loud was the sound produced by the contact of the fork 

 with the glass. Very much the same were the experiences of the 

 brother. The doctor relates the observations of a medical student 

 in Zurich, to whom notes of music were translated by certain 

 fixed colors, the high notes by clear, the low ones by dull colors. 



M. Pedrona, anopthalmologist of Nantes, states that he had a 

 friend who was accustomed to the simultaneous perception of 

 sounds and colors, but he avoided speaking of it, not wishing ta 

 be thought strange or to be an object of curiosity or a subject of 

 discussion. At one time a number of persons were repeating a 

 slang expression, which occurred in some popular story, "That 

 is as fine as a yellow dog," applying it in a jocular manner to all 

 kinds of things and actions. One of the company said of another 

 person, " Have you noticed his voice? It is as fine as a yellow 

 dog." M. Pedrona's friend replied seriously and with emphasis, 

 "His voice is not yellow; it is pure red." The downright 

 earnestness with which the remark was made, caused the whole 

 company to laugh outright. "What," said they, "a red voice? 

 What do you mean?" The gentleman had to explain the pe- 

 culiar faculty which he possessed of seeing the color of voices. 

 When he had done this each person present desired to be in- 

 formed of the color of his own voice. The voices were charac-
