I. " On the Influence of Carbonic Anhydride and other Gases 

 on the Development of Micro-organisms." By PERCY F. 

 FRANKLAND, Ph.D., B.Sc. (Lond.), F.I.C., Assoc. Roy. Sch. 

 of Mines, Professor of Chemistry in University College, 

 Dundee. Communicated by Professor T. E. THORPE, 

 Ph.D., F.R.S, Received December 18, 1888. 



In consequence of a paper which has appeared in the last number 

 of the ' Zeitschrift fur Hygiene,' by Dr. Carl Frankel, entitled " Ueber 

 die Einwirkung der Kohlensaure auf die Lebensthatigkeit der Mikro- 

 organismen," 1 have been led to publish the results of some prelimi- 

 nary experiments on the same subject which I made in the spring of 

 1886, but which, owing to my attention being at that time devoted to 

 investigations in other directions, 1 was obliged to put on one side. 

 Although the methods which I adopted in my experiments are essen- 

 tially different from those which Frankel has employed, yet the results, 

 so far as they can be compared with his, are on the whole concordant.
