uniformity in the publication of these results ; accordingly it continues 

 the Travaux along similar lines, though outside contributions are solic- 

 ited also. Three numbers make a volume, the fascicles to appear at ir- 

 regular intervals. We extend to our colleague hearty congratulations 

 upon the amount and (luality of the researches which have been issued 

 from his laboratory since the first appearance of the Travaux in 1897.

The publishers announce that 100,000 of these dictionaries have 

 been sold. New editions of the three popular issues are announced, 

 the latest being the pocket size. This compact and richly bound little 

 book (i X TiVz X 6 inches) contains 837 pages, definitions and pronun- 

 ciations of 30,000 words, with numerous useful tables, and sells for $1. 

 It cannot take the place of the author's larger dictionaries, as the defi- 

 nitions are too brief; they are however adequate in most cases to their 

 purpose and the list is very complete and well chosen. c. j. h. 



[nfonnatio7i Wanted. — The psychophysiology of anaesthesia is a 

 productive subject greatly in need of adequate investigation and dis- 

 cussion. Both pure science and practical surgery have doubtless much 

 to gain from a deeper-going study of experiences under ether, cholo- 

 form, nitrous oxide, etc., than has as yet been made. Scientific litera- 

 ture has frequently contained accounts of isolated individual experi- 

 ences reported most often because of their strangeness. A" very large 

 number of descriptions of the ordinary experiences is what is now de- 

 sired, and to this end blanks have been prepared on which replies to 

 certain simple questions may be written. All persons, and especially 

 hospital surgeons, officers of medical societies, and instructors in med- 

 ical schools, are respectfully requested to send to the undersigned for 

 as many blanks as they care to distribute among persons who have been 

 under an anajsthetic. These will be gratefully sent, and received when 

 filled out. George V. N. Dearborn.
