flianvm; also a fossil pupa, this being the first instance of a land shell 

 being found in the coal formation. He also informed him that a jaw- 

 bone had been found in the Eed Sandstone of Prince Edward's Island, 

 which sandstone he considered equivalent to the Red Sandstone of 

 Connecticut and Pennsylvania. He lent him a rough drawing of the 

 jaw by Mr. 'J. W. Dawson. Sir Charles also showed Dr. Lea draw- 

 ings of a cetacean, which had been described by Dr. Leidy, from the 

 Greensand of Mullica Hill, N. J. ; and the drawings of the vertebra 

 of another, said to be from the Greensand of Greenwich, N. Y. But 

 Sir Charles was satisfied that the latter was not from Greenwich, IST. 

 Y., and was therefore not to be considered; but there remained the 

 Mullica Hill specimen, and a tooth, which Mr. Wetherill, of Burling- 

 ton, ]Sr. J., had given Prof. H. D. Eogers, but which, when Sir Charles 

 saw the professor, was packed up, and therefore could not be seen. 

 Sir Charles remarked that this matter of a cetacean being discovered 

 in the chalk formation was of great interest, as there never had been 

 one found so low in the strata. Some days after Sir Charles called on 

 Dr. Lea, and they again talked over the subject of the bones of the 

 ' Greensand formation of ISTew Jersey, and the jaw of the Red Sandstone 

 of Prince Edward's Island. He mentioned that he had written to Dr. 

 Leidy before leaving America in regard to it, but he was not sure that the 

 box containing the bone had ever reached New York. He had ordered it 

 sent to the Clarendon Hotel, where he was stopping, but ithad not arrived 

 before he left there. He expressed great desire that the fossil bones 

 from the Greensand of New Jersey should be collected for the Acad- 

 emy of Natural Sciences, and regretted that the tooth, which had been 

 sent Professor Rogers, had been lost, as it was of great importance to 

 the geologist of the State of New Jersey. Sir Charles told Dr. Lea 

 that Professor Rogers now could not remember anything about it. He 

 said that a drawing was made of it by Mr. Conrad, and that it was in 

 the form of a 3Iammifer ; that Mr. Lesueur had seen it, and that it was 

 similar to a seal's. They also talked over the New Red Sandstone of 

 Nova Scotia, which Sir Charles thought to be the equivalent of that of 

 Connecticut, New Jersey, and Pennsylvania. The "foot-marks" {Sau- 

 ropus primwims) from near Pottsville, Pa., discovered and described 

 by Dr. Lea, was a very interesting subject to Sir Charles, who exam- 

 ined a specimen of the rock, which Dr. Lea had with him. It suri)rised 

 him from the bear.ty of the raindrop pits which covered the specimen, 

 and he expressed great satisfaction on seeing it. He was surprised to 

 find it was so low down in the series. Indeed, he seemed to have taken 

 Professor Rogers's opinion, and as he said, quoted from that. Dr. Lea 

 then read a few i)aragraphs from his paper to show him exactly how 

 many feet (1,700) below the conglomerate of the Coal Measures these 

 "foot-marks" were found, and on reading the quotation from Professor 

 Rogers that these '• 'footuiarks' were but a few hundred feet below the 

 Coal Measures, and only a single leaf in the creation," he emphatically
