means of the excellent cliff sections, the sug- 

 gestion of the occurrence of such deposits. 

 Pre-Pleistocene deposits were found at Third 

 Cliff, twenty miles southeast of Boston, and 

 possibly at Peaked Cliff, southeast of Ply- 

 mouth. 



The section at Third Cliff shows yellow 

 clays at the base conformably overlain by 

 yellow and white sands and succeeded by a 

 bed of bright red sands with an unconformity 

 at their base. On the eroded edges of the 

 red and white beds are deposited dark, glau- 

 conitic and lignitic clays and sands. The 

 entire series of beds has a total maximum 

 thickness of sixty or seventy feet, and out- 

 crops for a half mile along the cliff face. 

 Absolutely no erratic material occurs either 

 within the beds themselves or along the lines 

 of unconformity. 



The lithologic characters of the lower beds 

 are like those so persistently characteristic of 

 the Cretaceous from Marthas Vineyard to 

 New Jersey; while the upper beds of dark 

 clays appear to be homologues of the Miocene 

 at Gay Head and at Marshfield. This fact, 

 together with the evidence of the unconformi- 

 ties and of the lignites is being examined 

 with a view toward suggesting probable cor- 

 relations with the deposits worked out at Gay 

 Head by Professor Woodworth (Bull. Geol. 

 Soc. Amer., VIII., 1897, 197-212); although 

 the absence of specific paleontologic evidence 

 renders such correlation merely tentative. 

 The detailed descriptions of the beds and the 

 conclusions inferred with respect to their age 

 will be published in a later paper. .

exoglossum in the delaware. 

 The occurrence of the little minnow, Exo- 

 glossum maxillingua (Le Sueur), in the Dela- 

 ware basin is of interest. So far as I am 

 aware, it has not been taken in any of the 

 tributaries of the Delaware before the capture 

 of two examples which , I caught in the Red 

 Clay Creek, Chester County, Pa., during 

 April of 1904. In this instance I am in- 

 debted to Mr. Alfred C. Satterthwait, who 

 assisted me in securing the specimens. When 



first seen, I was under the mistaken impres- 

 sion that they were simply young unmottled 

 examples of Catostomus commersonnii. 



In the Susquehanna basin this fish is abun- 

 dant and I have also met with it in tribu- 

 taries of the Allegheny in Pennsylvania, espe- 

 cially near Cole Grove, in McKean County.

THE BRAIN OF THE HISTOLOGIST AND PHYSIOLOGIST 

 OTTO C. LOTON. 



Professor Loven, the Swedish histologist 

 and physiologist who will be best remembered 

 for his discoveries of the endings of the taste- 

 fibers in the papillae of the tongue of mammals, 

 as well as of the vaso-dilator nerves, had ex- 

 pressed it as his wish that his brain be pre- 

 served after death and studied by his friend 

 and associate, Gustaf Retzius. 



With characteristic care and skill Professor 

 Retzius has just published his studies upon 

 Loven's brain in Biologische Untersuchungen, 

 Vol. XII., 1905. The brain exhibits a richness 

 of fissures and these are marked by a superior 

 degree of tortuousness and ramification. The 

 subparietal region is very complex in its sur- 

 face configuration, while the central (motor) 

 regions are only moderately developed. The 

 cortical centers for speech and language for- 

 mation are notably large, and Professor 

 Retzius brings this fact into relation with 

 Professor Loven's notable powers of clear, ex- 

 act and logical expressions of thought in 

 words; less so in the way of oratorical finesse 

 than in the talented use of the best and most 

 adequate expressions. The weight of the 

 brain is not given in this report though its 

 size is said by Retzius to have been well above 

 the average. Edw. Anthony Spitzka. 



APPLES injured BY SULPHUR FUMIGATION. 



Recently some injured Esopus Spitzenburg 

 apples were received at the New York Experi- 

 ment Station with a request to diagnose the 

 trouble. They were of the first grade, each 

 fruit wrapped in paper, and packed in a bushel 

 box. The financial loss was important, as a
