United States Dispensatory spoke of them as occasionally employed in 

 cases of chronic diarrhoea. The last (20th, 1918) edition contains the 

 somewhat contradictory statement that they "are no longer prescribed 

 internally. Aromatic syrup of galls is sometimes prescribed." This 

 syrup is a form in which they were employed in the treatment of 

 diarrhoea. 



Officinal galls are derived almost exclusively from Quercus infectoria, 

 and this is recognized as their source in the United States Pharma- 

 copoeia. They are produced by Cynips gallcetinctorice Olivier, and are 

 of the well-known hard, spherical type, about ten to twenty milli- 

 meters in diameter. They are often known in commerce as the Aleppo 

 galls, since they formerly were largely produced in the vicinity of the 

 Syrian city of that name. 



The most significant feature of the use of galls by the Indians for 

 the same disease as that for which the officinal preparations were more 

 often used, is that the Indians use a type of gall differing radically from 

 that above described. Doubtless both owe their efficacy to the pres- 

 ence of tannin but it is clear that the Indian usage could not be a mod- 

 ern one, derived from that by the whites. 



Scientific Notes 



Hessian Fly: Supplementing previous outdoor experiments, to determine 

 whether or not certain strains of wheat are actually less severel}^ attacked by the 

 Hessian fly than others, the Department of Entomology of the Missouri Agricultural 

 Experiment Station is carrying through an interesting series of greenhouse experi- 

 ments. Some difficulty has been experienced in making growing conditions abso- 

 lutely vmiform, where a large series of varieties are tested and the conditions under 

 glass are naturally not exactly the same as in the field. Standard Missouri varieties 

 as well as others previously reported as ha\'ing resistant qualities are being used in the 

 experiments. The pest seems to breed and develop norma'ly indoors on all strains 

 tested, but in the first test just completed, some varieties are decidedly less severely 

 attacked than others. Chemical tests and observations on different structural varia- 

 tions of the indoor plants are also being made the same as in case of the field experiments.

Exiropean Com Borer In Connecticut; What appears to be a small infesta- 

 tion of the European Corn Borer, Pyrausta nubilalis Hubner, was found in Milford, 

 Conn., March 12, by assistant entomologists from the Agricultural Experiment 

 Station. The infestation Ues just north of the village, and at this vmting its limits 

 have not been definitely ascertained. Prompt measures will be taken to suppress the 



pest.
