ANNOTATIONS THE EASTMAN DENTAL CLINIC. THE opening of the Eastman Dental Clinic on Wednesday of last week is an important event in the record of the efforts made to provide for the dental needs of the children of London. For a long time the only institutions available for the care of children’s teeth other than extractions were the dental hospitals, and if time and distance had not limited the attendance they would have been overcrowded. The instit .tion of a large number of clinics in London and its suburbs by the London County Council has made conservative dentistry accessible to large numbers of children, but as the scheme is far from
child clientele only would not be adequate. For the training of dental nurses for employment in school clinics throughout the country the institution offers good facilities and the employment of such assistants to school dentists, with strict limitation of function, might well be more extensive than it is; but until the demand develops it would obviously be unwise to train more than can be easily absorbed. Another possibility is research, for which there will clearly be ample accommodation and.equipment, and probably clinical material which it would be a pity to a
waste. ____

the treatment of diseases of the gums and some surgical affections of the jaws, form a very valuable part of the work of the special dental hospital. Mr. Eastman’s object is to demonstrate, in a particular area, the beneficial effects on health of thorough and complete preventive and remedial treatment of the mouth and teeth from the earliest years. For this purpose the sumptuous building and equipment generously provided by Mr. Eastman are more than adequate, and the maintenance has been guaranteed by Lord Riddell and Sir Albert Levy, the chairman and honorary treasurer of the Royal Free Hospital, which the new building adjoins, and with which it is closely associated as regards management and contact. The orthodontic department is to be a special feature, and will go far to meet a growing demand for the treatment of the various forms of abnormal jaw development, which are more intimately connected with general health than is sometimes appreciated. Further possible developments of the clinic leap to the mind. Its association with the Royal Free Hospital suggests a school for the training of women dentists, but for that purpose

The first definite results from this research
are
reported in the current proceedings of the Society for Experimental Biology and Medicine.1 Healthy young women volunteers were secured for the experiment. They were isolated with great care from all chance infection. The experiments, moreover, were carried out in the months of June and July, 1930, when the incidence of colds in Baltimore was at a low level. Nasopharyngeal washings were taken from persons who were in the first 48 hours of a common cold infection. Half of each washing was put through a Berkefeld V candle and in each case the filtrate contained filter-passing anaerobes. The other half was filtered either through a Berkefeld W candle or an improved Seitz filter, when all attempts to demonstrate micro-organisms, either aerobic or anaerobic, in these filtrates failed. The experimental subjects were inoculated intranasally and the pharynx swabbed with small quantities of the same filtrate. In the first group of ten volunteers half received Berkefeld V filtrate and half Seitz filtrate. Two subjects in and
