any accumulation of stocks in the principal markets. It is further said that the export- 

 duty from the producing country has lately been raised again, a circumstance which 

 naturally contributes to make the prices still dearer. 



H. R. Jensen 1 ) recommends that in testing Peru balsam analytically the iodine value 

 of its cinnameine shall also be estimated, and that furthermore the rotation of the 

 initial 30 p. c. which pass over in the distillation of cinnameine shall be determined. 

 Cinnameine from pure balsam gave an iodine value of 23,8, whereas that isolated from 

 a synthetic product only gave 1,5. Distillation in vacuo (with a three-bulb flask) of a 

 cinnameine from synthetic balsam only gave inactive fractions, whereas of cinnameine 

 from natural balsam the initial 10 p. c. had rotation +5°40', the second lOp.c. -fl° 

 and the third 10 p. c. + 0°15\ Jensen believes that the distillation can also be con- 

 ducted under ordinary pressure. 



Another balsam which was examined at the same time, and of which the cinna- 

 meine was markedly rich in cinnamate was in Jensen's opinion probably adulterated 

 with storax. 



Pollantin. Judging from authoritative expressions of opinion, and from our own 

 experience, Pollantin-ointment, the new form of applying Pollantin, which was first 

 placed on the market by us in the year 1912, has been everywhere well received. In 

 almost all cases which have come to our knowledge, patients who, for whatever reason, 

 abstained from using the older Pollantin-preparations, have willingly taken to the salve 

 and have found in it a means of successfully combating hay-fever. 



We may also take this opportunity of referring once more to the Pollantin-tablets 

 of which we first made mention in our Report of April 1912. We prepared these 

 tablets on the advice of Prof. Dunbar as a remedy for the exceedingly tormenting 

 asthmatic troubles which afflict many patients in the later stages of hay-fever. The 

 tablets consist simply of Pollantin-powder levigated with sugar of milk, and (with 

 the exception of a neutral binding -material) they are free from any alien sub- 

 stance. We have had nothing but good reports of their efficacy last year. Before 

 placing these tablets upon the market, we again desire to call the attention of the 

 medical profession to this remedy, of which the mode of application is extremely 

 simple, and of which we shall be pleased to supply samples for experimental purposes. 



We also wish to point out once more to our customers, and in particular to the 

 pharmacists among them, that we are prepared to exchange old tins of liquid Pollantin 

 bearing control-numbers from 161 (inclusive) downwards for fresh serum, and we there- 

 fore request them to look out such numbers from their stock and return them to us. 

 Upon receipt the new tins will be forwarded immediately. Powdered Pollantin, if 

 properly stored, has unlimited keeping quality, and for that reason, as we have 

 repeatedly stated, we cannot undertake to exchange it. 



After laborious experiments extending over several years, we have succeeded in 

 producing a UNIFORM SERUM, suitable for SPRING as well as for FALL Hay Fever 

 and kindred troubles. Beginning with the coming season we shall, therefore, put up 

 Pollantin, powder as well as liquid, in a single style of packing only, thus obviating 

 the possibility of mistakes which, it would appear, happened occasionally, such as 

 patients receiving Fall serum when requiring Spring serum, and vice versa.
