most generally found in the midst of clumps of red corpscules. In 

 several cases a faint, delicate line, curved the other way, was seen 

 connecting the ends of the crescents. Marchiafava and Celli also 

 describe these crescentic forms, and suppose them to be developed 

 from the plasmodia (2). 



In two cases of intermittent fever the crescents were found in 

 the blood at the same time that the corpscules contained plasmodia. 

 * * * The number of crescents varied much in difPerent cases. 

 In all of the fatal cases the crescentic bodies were found in great 

 numbers, along with other bodies which were seemingly identical 

 with the hyaline bodies found in the capillaries after death. Several 

 times in the same preparation with ciliated bodies, free cilia were 

 seen. The latter appeared to be the same size as those attached 

 to the bodies, and like these had small nodes among them. They 

 moved rapidly through the blood, sometimes with a spiral 

 motion similar to that of a spermatozoon (3). In their onward 

 motion they often came in contact with a red bood corpuscle and 

 would violently indent this, or they would agitate a whole group 

 of corpuscles. 



The motion of the cilia, both when attached and free, seemed 

 to have a certain rythm : they woidd move slowly at first, the 

 motion increasing until it became very rapid, then it would become 

 slower and nearly cease, again to become very rapid. In addition 

 to the motion of the filaments, a wave-like motion of the periphery 

 of the body was often seen. ****** 



The importance of these recent discoveries in malaria can 

 hardly be overestimated. Not only is a new territory opened to 

 the pathologist, but to the clinician the sure means is given, by 

 a simple examination of the blood, of diagnosticating accurately 

 the most complex, and sometimes most terrible of diseases, and 

 in which more depends on a speedy and certain diagnosis than 

 in any other disease. Not only is he able to designate the dis- 

 ease as such, but in most cases the particular form. — Med. News. 



A WRITER in the Dental Review in an interesting article, " Mi- 

 croscopy in Dentistry," says : The microscope has revealed much 

 to the dentist regarding the teeth and their development. It has 

 much more to disclose. It is telling us much regarding the diseases 

 of the teeth and the environing tissue. It has recently shown 

 us -the origin of one of the acids which is found in the 

 mouth. We are just entering a field in which there is much work 

 to 1)6 done, and truly the laborers are few. Large opportunities
