On Friday afternoon, October 8, the 

 pegmatite dikes at Collins Hill, Portland, 

 were visited. Twenty-two mineral species 

 have been found at this locality and the party 

 was fortunate in collecting, among other spe- 

 cies, flat, purple, transparent apatite crystals 

 which showed strongly developed facets of 

 the first and second order prisms, the first 

 and second order pyramids, and the basal 

 pinacoid. The relations of the pegmatites to 

 the Bolton schist, the intrusive contacts of 

 the Maromas and Glastonbury gneisses with 

 the schist, the interglacial course of the 

 Connecticut river were brought to the atten- 

 tion of the party. 



Friday evening an excellent buffet lunch 

 was served at Fish Hall by invitation of 

 Wesleyan University. After the lunch the 

 party listened to an address by Professor W. 

 M. Davis, whose classic work on the compli- 

 cated structure of the Connecticut Triassic 

 has long been a model for structural geol- 

 ogists. During the lecture he gave a most 

 interesting account of the methods ho em- 

 ployed in working out the fault structures in 

 the vicinity of the excursion of the following 

 day. He also discussed the mechanics of the 

 faulting and erosion which produced the 

 striking topography of the Connecticut valley. 



At the conclusion of this lecture. Professor 

 Eice, also a pioneer student of the Connect- 

 icut Triassic, described in detail the faulted 

 structures between the Lamentation Mountain 

 and the Hanging Hills blocks which were to 

 be visited on the morrow. Professor Foye 

 exhibited a collection of minerals from the 

 pegmatite dikes in the vicinity of Middle- 

 town, and gave a brief account of the locali- 

 ties from which they were obtained. 



Saturday morning the party was conducted 

 by autotruck and on foot to some of the step 

 faults and drag dips along the line of the 

 great fault described by Professor Eice the 

 evening before. 



Lunch was eaten at Spruce brook by a 

 picturesque waterfall. After lunch the resig- 

 nation of the secretary who had been in office 



for eighteen years was accepted, and Professor 

 Foye was elected for an indefinite term. 



At Spruce Brook the contact of the main 

 trap sheet with the overlying conglomerate 

 was studied. Pebbles of the underlying trap 

 were found in the basal layers of the con- 

 glomerate and the contemporaneous character 

 of the main sheet was established. 



At two localities, lying west of Lamentation 

 Movmtain, the problematic " pillow lavas " of 

 the anterior sheet were examined, and their 

 origin discussed by members of the party. 

 The Meriden " ash bed," also within the 

 anterior sheet, was visited and created con- 

 siderable discussion, but the general opinion 

 favored a volcanic source for the deposit. 



At the Lane quarry north of Meriden was 

 seen a pahoehoe surface of lava overlain by a 

 denser flow showing that, in this locality at 

 least, the main trap sheet did not consist of 

 but a single flow. 



None of the many enjoyable and profitable 

 excursions taken by the ISTew England geolo- 

 gists has been more successful than this one.

" PHYSIOLOGICAL REVIEWS " 



A NEW journal under this name will be pub- 

 lished quarterly by the American Physiolog- 

 ical Society under the editorial direction of 

 W. H. Howell, Baltimore; Eeid Hunt, Boston; 

 F. S. Lee, New York; J. J. E. Macleod, To- 

 ronto; Lafayette B. Mendel, New Haven; H. 

 Gideon Wells, Chicago; D. E. Hooker, Man- 

 aging Editor, Baltimore. 



The main purpose of the Physiological Re- 

 views is to furnish a means whereby those in- 

 terested in the physiological sciences may keep 

 in touch with contemporary research. The 

 literature, as every worker knows, is so exten- 

 sive and scattered that even the specialist may 

 fail to maintain contact with the advance along 

 different lines of his subject. The obvious 

 method of meeting such a situation is to pro- 

 vide articles from time to time in which the 

 more recent literature is compared and sum- 

 marized. The abstract journals render valu- 

 able assistance by condensing and classifying
