37(6 Mammalian Cerebellum. Part I. The De- 

 velopment of the Cerebellum, in Man and the Cat: 

 By Bert Brenette Steoud. This paper is 

 introduced by sections on technique and termi- 

 nology ; also by an historical review. The de- 

 velopment of the cerebellum of both man and 

 the cat is presented in a series of drawings and 

 descriptions of all of the imjiortant stages. In 

 1891 Herrick gave a brief description of the 

 development of the cerebellum of the mammal 

 and reptile, in which he showed that this organ 

 arises not from a median anlag, but from two 

 lateral centers of proliferation from which the 

 neuroblastic elements migrate dorsad and mesad. 

 In 1894 Schaper verified and amplified these 

 observations in the teleosts. Mr. Stroud has 

 fully illustrated the process in his two types, 

 and has then traced the development of each of 

 the major divisions of the adult organ. His 

 pajjer is accompanied by eight plates and a 

 bibliography. 



Notefs on Child Experiences: By C. L. Her- 

 rick. I. Anthropomorphization of Numerals. 

 The strong tendency of children toward per- 

 sonification has led in the case cited to a phe- 

 nomenon not unlike pseudochromsesthesia. The 

 boy of ten years habitually personifies and 

 visualizes his numerals and attributes to each a 

 moral nature in keeping with his form. II. 

 Hallucinations of Vision in Children. In the 

 course of a description of certain unusually 

 vivid visual hallucinations which the author 

 experienced in his own childhood, he takes occa- 

 sion to criticise the recent statistical studies of 

 the power of visualization. The average un- 

 trained observer is unable to tell whether he 

 truly visualizes or not, so that much of the 

 work done on the basis of I'ecent statistics is 

 is fallacious. 



The Cerebral Fissures of two Fhilosophers, 

 Chauncey Wright and James Edward Oliver : By 

 Burt G. Wildee. A brief comparison of the 

 fissural patterns of these brains shows, in both, 

 the frontal region unusually high and wide and 

 the supertemporal fissure larger than common ; 

 but the very exceptional features of Wright's 

 cerebrum are not repeated in Oliver's. But all 



estimates of the extent and significance of their 

 peculiarities will be only provisional until the 

 careful comparison of many average brains sup- 

 plies one or more types or standards. 



Formalin for the Preservation of Brains. [Pre- 

 liminary Note] : By Pierre A. Fish. A mini- 

 mum shrinkage and loss in weight, cheapness 

 and rapidity of action are the advantages 

 claimed for the mixture proposed. 



The Physiological Condition of Consciousness : 

 By De. Paul Carus. This article was called 

 out by Professor Herrick' s reply to Dr. Carus' 

 article in the Journal of Comparative Neurology 

 for September, 1894. Dr. Carus defends his 

 use of the words 'feeling' and 'intelligence,' 

 and reviews his arguments for regarding the 

 corpus striatum as the seat of consciousness in 

 the sense of an organ by which through some 

 kind of a mechanical arrangement the connec- 

 tion between the memory-images are established 

 so as to produce by their interaction the con- 

 dition of consciousness. A bibliography accom- 

 panies the paper. 



SOCIETIES AND ACADEMIES. 



new YORK academy OF SCIENCES. 



The first regular meeting of the year 1895- 

 96 was held on Monday evening, October 7. 

 No formal program had been announced be- 

 yond regular business, but after this had been 

 transacted, the members present gave personal 

 sketches of the work of the summer, and 

 touched particularly on the meetings of the 

 American Association, its afliliated societies and 

 the British Association. 



A proposed plan for the meeting of the British 

 Association in joint session with the American 

 Association at San Francisco in 1897 was 

 brought up and informally discussed, but no 

 action was taken.

 Secretary.

A REGULAR meeting of the Academy was 

 held on the evening of Friday, October 4, at
