same class of individuals, — both ailments were classed together under 

 the general name of "hayfever". But since Dunbar's publications that 

 name is given only to the complex of symptoms which is provoked 

 by the effect of pollen on predisposed individuals, and removed by a 

 specific serum. Bonnier, however, as will be seen, does not apply the 

 expression "rhiime des foins" in this, its only correct sense; he uses this 

 term for both affections, in the old fashion, although their causes are 

 fundamentally different. Bonnier would immediately recognise the 

 great distinction between Coryza nervosa and true hay fever if he would 

 amplify his theories by practice, test the excitability of a few of his 

 patients by means of pollen extracts, and then proceed to remove any 

 symptoms of excitation which may manifest themselves, with the specific 

 serum. 



The error into which Bonnier has fallen in his views on the treat- 

 ment of "hay fever" is shown by the many reports which we receive, 

 principally from Western Europe, and above all from England, of the 

 excellent action of our Pollantin. To these reports must be added one 

 which has just come to hand from a medical practitioner in Paris, who 

 has experienced its beneficial effects on himself. 



SafroL Enormous quantities of this article continue to be sold, 

 the United States especially showing strong interest in the preparation. 

 We refer to the statements under camphor oil (p. 29), and will only 

 add thereto that during the period under review no alterations in 

 price have taken place. 



Tannothymal. During the past year or so this preparation has 

 been much used in the Veterinary Institute of Leipzig University in 

 the treatment of diarrhoea in animals. According to a communication 

 by Prof. A. Eber 1 ), Director of the Institute, it has been found of 

 particular service (in doses of 4 to 5 g.) against diarrhoea of calves, 

 a complaint which, owing to change of food, often causes much 

 trouble in animals acquired for experimental purposes. 



Thymol. It has lately been noticeable that those Hamburg firms 

 who have earned the doubtful distinction of having thoroughly ruined 

 the trade in this article are no longer quite so persistent as formerly 

 in undercutting every reasonable quotation, and it is to be assumed 

 that they are at last growing tired of the practice. It is to be hoped 

 that some understanding may be arrived at, which will make business 

 in the article more satisfactory again in the future. That enormous 

 quantities, both of thymol and of ajowan-seed, are available in Europe 

 is evident from the fact that although the raw material has risen in 

 price by about 2 5°/ during the past few months, the thymol quot- 

 ations at present show no inclination to follow suit.
