" Science Progress " 



With the commencement of our twelfth Volume further 

 changes, but this time only small ones, will be made in the 

 arrangement of our sections : the Recent Advances will be 

 given first place, and the Essay-Reviews will be put in small 

 print between the Essays and the Reviews, as seems reason- 

 able. The Recent Advances head our Contents because in 

 that position they enable the busy reader to see at a glance 

 the most important scientific work which has been done during 

 the quarter, and he can then peruse at leisure the more specia- 

 lised papers which follow under the heading of Articles. The 

 Editor would like to take this opportunity publicly to thank 

 the contributors of Recent Advances for their work, which 

 requires constant attention to the literature of the subjects 

 with which they deal and, often, much consideration in the 

 choice of the matter which is to be referred to in the short 

 space available. We hope to add later occasional Recent 

 Advances on various branches of Applied Science ; but the 

 reader will understand that these subjects are too large to be 

 dealt with in any single quarterly publication except in very 

 brief abstract.

It has been a striking and a fortunate circumstance that with 

 each of the three remarkable therapeutic strides of the last 

 century and a quarter, of vaccines, of sera, and of organic 

 extracts, the first application of each new step has at the same 

 time been the most successful. The prophylaxis of small-pox 

 by calf vaccine, the treatment of diphtheria by antitoxic serum 

 and the cure of myxodoema by preparations of the thyroid 

 gland have never been equalled in their success by similar 

 efforts in other diseases. 



The foundation of the specific treatment of diphtheria was 



laid by Behring when, in 1890, together with Kitasato, he 



successfully immunised and treated animals for the infections
