188 Correspondence — Clement Reid. 



explanation is that this portion originally drained into the Whitewater 

 over tlie present col of Grolden Pot. In discussing this explanation, 

 it appears that the Tisted tributary has the characters of a consequent 

 stream ; but there is no very good evidence, except alignment, of the 

 former connexion of the two basins. On the other hand, the Farnham 

 Kiver rather appears to have originated in a Chalk surface than in 

 Wealden beds ; and thus it and its tributaries may have been developed 

 on the Chalk portion of the peneplain of the Weald. Thus the 

 Farnham stream appears to present a case of the conversion of a Chalk 

 valley into a Wealden one in its lower part, while in the Caker stream 

 the reverse is the case, and it is the upper part of the stream that has 

 entered Wealden beds. 



On April 1st, 1908, at 7"45 p.m., a Special General Meeting "will 

 be held, to consider the following resolution, signed by ten Fellows of

 assuming that this can be done under the present charter."

 Society, and, if so, whether as Fellows or as Associates." 



GLACIATED ERRATICS IN SCILLY. 



SiK, — During September, 1907, Professor A. G. IS'athorst and 

 I made a flying visit to Scilly in order to see the very interesting 

 deposit with striated erratics discovered by Mr. (ieorge Barrow. On 

 St. Martin's Head, the highest point in the Isles, we obtained some 

 additional evidence. When I formerly visited this spot in company 

 with Mr. Barrow we did not succeed in tracing the striated erratics to 

 a gi'eater height than 100 feet above the sea, though we noticed 

 unstriated fragments of a similar buff sandstone at higher levels. 

 During this later visit Professor Nathorst and I worked slowly up the 

 slope leading to the Beacon, turning over the boulders of sandstone 

 half imbedded in the soil. We thus found that though at the liigher 

 elevations the exposed surfaces of this rock had all lost their striae 

 through the action of the weather, yet iu every case the surfaces 

 protected by soil were beautifully glaciated. We traced these erratics 

 up and up, till we found an imbedded block at a level less than 

 20 feet below the highest point, which is marked 160 feet above 

 Ordnance datum. 



On returning to London I showed these striated masses of reddish 

 or buff tine-grained sandstone to several of my colleagues, for I could 

 not recognize them as belonging to any Cornish rock. Neither could
