Probably few American physiologists re- 

 ceived the news of Ludwig's death without 

 a feeling of sadness far beyond that occa- 

 sioned by the loss to science. Ludwig liked 

 America and Americans, and many of his 

 colleagues upon this side of the Atlantic 

 have been his pupils and have found in 

 him a warm personal friend. His wit, his 

 sympathj', his breadth of mind, his love of 

 books and of music, were conspicuous. To 

 work with him was to receive the undy- 

 ing stimulus of a master mind and to feel 

 the charm of a simple, sweet, winning per- 

 sonalitj'.

COBBESPONDENCE. 



THE FEOG WAS NOT BRAINLESS BUT DECERE- 



BEIZED. 



In the report of the meeting of the Asso- 

 ciation of American Anatomists last De- 

 cember in Science for March 15, 1895, p. 

 297, it is said that ' Dr. Wilder exhibited a 

 brainless Frog, etc' The animal shown 

 had been deprived of his cerebrum Dec. 7, 

 1894, for demonstration to my class in physi- 

 ology of the points first, I believe, observed 

 by Goltz. The brain was transected at the 

 diencephal (thalami) and the entire cere- 

 brum removed as described by me in 1886.* 

 The frog was unusually large and vigorous, 

 and was exhibited partly on that account, 

 and partly because when it dies the condi- 

 tion of the brain will be determined and re- 

 ported to the Association. At this ■WTiting, 

 however, it is stQl living and has been

 others while maintaining its balance on a 

 cylinder hy ' backing ' instead of going for-^ 

 ivard as usual. 



The object of the present note is to repro- 

 bate the use of brainless and decerebrized as 

 interchangeable terms. The latter alone 

 was used by me at the meeting, and was 

 accessible in type-writing to all who were 

 present. Ifevertheless, both at that time 

 and afterward, there appeared many news- 

 paper paragraphs as to ' Dr. Wilder's 

 brainless frog.' An attempt to correct the 

 misapprehension through the Associated 

 Press onlj' made the matter worse, for I 

 was promptly credited with ' another brain- 

 less frog.' 



Perhaps, however, we ought not to con- 

 demn the popular confusion of terms too 

 strongly in view of the following example 

 among professional anatomists. At the 

 Tenth International Medical Congress in 

 Berlin, August 5, 1890, Professor Sir Wil- 

 liam Turner, F. E. S., etc., delivered an 

 address, the official title of which, as printed 

 in the Journal of Anatomy and Physiology for 

 October, is ' The Convolutions of the 

 Brain ;' the real subject is The Fissures of 

 the Cerebrum.

TEST-BOOK OF INVERTEBRATE MORPHOLOGY. 



To THE Editor of Science : A reply to 

 a book review is undoubtedly in manj' cases 

 inadvisable, but there are certain state- 

 ments in the review of mj^ Text-book of 

 Invertebrate Morphology in your issue of 

 May 3d which seem, as a matter of justice, 

 to call for some comment. A reviewer has 

 a perfect right to express his opinion con- 

 cerning the views set forth by an author, 

 but the latter has a right to expect that his 

 statements will not be misrepresented either 

 directlj' or by implication, and I wish to 

 call attention to certain misrepresentations
