THE LYMPH SPACES IN FASCI.«. 91 



of the Ehrenbergian genus, Ceratoneis, for the purpose of 

 separating the forms embraced under it from the genus 

 Nitzschia, to which they belong. Grunow has well 

 described Ehrenberg's genus, Ceratoneis, as a medley of 

 heterogeneous forms, and retained the generic name to 

 receive the single species = Eunotia arcus, W. Sm., in which 

 he is followed by Professor H. L. Smith, There may 

 indeed be good reason for retaining the generic name so 

 limited, but strong objections may be urged against the 

 genus as Ehrenberg and Kiitzing left it. Too much praise 

 cannot be given to Dr. Pfitzer for his observations on the 

 genus Nitzschia. No doubt the forms investigated by him 

 constitute but a small proportion of those comprehended 

 under this extensive family ; but the structural characters 

 he has illustrated, in such as he has examined, may serve as 

 a clue to further investigations, and can scarcely fail to lead 

 to satisfactory results. — [From the ' Journal of Botany.'] 



The Lymph Spaces in Fascia ; a New Method of Injec- 

 tion. By H. P. BowDiTCH, M.D., Assistant Professor of 

 Physiology in Harvard University.^ 



The lymph spaces existing between the tendinous fibres 

 of fasciae, and the connection of these spaces with lymphatic 

 vessels, have been well described and figured by Ludwig 

 and Schweigger-Seidel in their monograph on this subject.- 



The researches of Dr. Genersich^ have shown that the 

 fasciae, in virtue of this structure, play a very important part 

 in keeping up the flow of lymph through the lymphatic 

 vessels. His first experiment was as follows : — A piece of 

 fascia was removed from the leg of a dog, and tied over the 

 mouth of a small glass funnel with the inner side («'. e. the 

 side next to the muscles) uppermost. A few drops of a tur- 

 pentine solution of the extract of alcanna root were then 

 placed upon this surface, and the fascia alternately stretched 

 and relaxed by partially exhausting the air from the funnel 

 and letting it return again. In this way the colouring 

 matter was made to penetrate into the spaces between the 

 fibres of the fascia, and to enter the lymph vessels on the 

 opposite side. The same result was obtained when the 

 colouring matter was injected between the muscle and the
