30 THE ESSEX FIELD CLUB. Desiderata for the Library.—Mr. W. Cole called attention to the Circular which had been sent out giving a first list of parts and volumes of various publications needed to complete sets in the Library. He pleaded strongly for kindly aid in making the library more complete and useful to enquirers. THE 445th MEETING. Saturday, 27TH February 1915. The fourth meeting of the Winter Session was held at 6 o'clock at Stratford, as usual. The President in the chair. During the afternoon the Toynbee Natural History Society (of which our member, Mr. D. J. Scourfield, is President) visited the Museum, and afterwards joined in the evening meeting. Mr. George W. Ivey, of "Alcyone," Harrow Drive, Romford, was elected a member. In anticipation of the Annual Meeting, nominations were made of officers and members of the Council (see report of the Annual Meeting). War-Time Field Meetings.—Mr. Percy Thompson said that the Council and Officers had carefully considered the possibilities of holding Field Meetings during the coming spring and summer. Very considerable restrictions had become necessary owing to the military occupation of our County. Any meetings on or near the coast would be absolutely barred, and therefore it would be necessary to organise meetings in other and more accessible districts in the county and around London, and in some of the Public Gardens and Museums. Particulars would be sent to members as soon as possible in each case. All would appreciate the peculiar difficulties attending the planning and carrying out excursions of large parties during the present times of national stress and anxiety. Incisor Teeth of Rhinoceros.—Mr. E. T. Newton, F.R.S., exhibited some incisor and canine teeth of the Indian Rhinoceros, and called attention to their peculiar form. There were only two broad incisors in the upper jaw, one on each side, and sometimes a very small one behind these. The front of the lower jaw was occupied by a pair of large triangular teeth usually regarded as canines, but in the position of incisors, and between these a very small pair of cylindrical incisors. African Rhinoceroses have no teeth in the front of either upper or lower jaw, except perhaps rudiments which are never functional. British Pleistocene Rhinoceroses are said to be most closely related io the African species, and it seemed probable therefore that they likewise had no incisor teeth, and this would account for the fact that Rhinoceros incisors have not been met with in British Pleistocene deposits. Bone Polishing Implements.—Mr. H. Mothersole sent for exhibition some bone implements used by the late Mr. W. Brown, cricket-bat maker, of Chelmsford, for the purpose of burnishing the backs of the bats after they had been planed and rubbed down with sand paper ; they were then polished; the face of the bat being oiled only. Mr. Brown's son states that they were used about 50 years ago. I have enquired of other makers, writes Mr. Mothersole, who were
