The absorption band of water vapor at 0.94 μ is studied photographically by means of a concave grating spectrometer. Twenty eight component lines are observed and measured on a comparator as well as on a Moll microphotometer. This band shows something of a doublet form which suggests that the H2O molecule has a triangular form with the oxygen atom at the vertex of an obtuse angle. The lines agree closely with some of the absorption lines in the solar spectrum as measured by Abney in 1880.

A new method for the biological assay of vegetable purgatives based on the numbers of wet faeces excreted by groups of mice after dosing is described. The relation of the number of wet faeces per group of mice to the logarithm of the dose was found to be linear. A cage has been specially designed for this assay and it has been found advantageous to incorporate a definite proportion of water in the diet during test. 40 mice divided equally into 4 groups were used in each assay. 2 groups received the standard preparation and the other 2 groups received the test preparation. The standard deviation of a single determination based on 9 such assays was estimated to be 15.7 per cent. For rhubarb and its preparations, a“6-point”assay is advocated. With suitable restric-tion in the design of the assay, it is possible to calculate the potency by simple methods. Powdered crude drugs are used as laboratory standards in the assay of senna and rhubarb. The doses of cascara bark required to produce distinctive responses are too inconveniently large to be administered in suspension. It was found possible to use a potent extract of cascara in place of the powdered bark as a laboratory standard. Examples of the assay and the subsequent calculations are given. The method described is not only convenient in use but also gives a comparatively high degree of accuracy. The method has been successfully applied to senna leaf, senna fruit, rhubarb, cascara sagrada and extracts and commercial preparations made from these drugs, pure glycosides(sennosides A and B) and pure anthracene compounds(aloe emodin and aloe-emodine anthranol).

(1)本文详述植物性泻药的一种新的生物测定法,此法係用小白鼠在服药后所排出的濕粪数为基础,以定泻药的效价。(2)小白鼠服药後所排出的湿粪数与剂量指数的关係经证明为一直线。(3)本法所用鼠笼係特别设计,并证明在饲料内加入一定量的饮水,具有多种优点。(4)番泻效价的测定,每次用小白鼠4组,每组10只。2组给与标准品,另外2组给与试验品。根据9次试验的结果,试验的标准差是15.7%.(5)大黄效价的测定,以采用“6点”法为宜,即每次试验用小白鼠6组,3组给与标准品,另外3组给与试验品,所得的准确度与上述相仿。波希鼠李皮浸膏的效价测定,则用“4点”法或“6点”法均可。(6)所有试验一律采用粉状生药为实验室的比较标准,但是波希鼠李皮的效价太低,它的粉末不适於作为标准之用,可用波希鼠李皮乾浸膏来代替,作为比较标准。(7)本文对於效价测定及其计算方法都举例说明,并介绍了比较常法为简捷的相关效价计算法。(8)本法不但方便易行,而且有相当高的准确度;曾用在番泻、大黄、波希鼠李皮及其制剂,以及一些纯粹的蒽醌衍生物的效价测定,都获得了满意的结果。

In view of the necessity of a rapid and accurate process for the deter-mination of fluorine applicable in the analysis of sodium fluoride and otherfluorine compounds,the author has established a new volumetric processconsisting in the titration in aqueous-alcoholic medium with ferric nitrate asstandard solution and sodium salicylate as indicator.All of the methods,published by Guyot,Greeff,Fairchild andVisintin proposed for the determination of fluorine using ferric solutionas standard,are based on the reaction:6NaF+FeCl_3→Na_3FeF_6+3NaCl. But the sodium ferric fluoride thus formed is fairly soluble in water and makesthe end-point unclear,therefore the titration can not be performed accurately.This seems to be due to the fact that the following two reactions advancesimultaneously,and accordingly the formation of sodium ferric fluoride is in-complete in aque(?)us medium:3NaF+Fe(NO_3)_3→FeF_3+3N_aNO_33NaF+FeF_3→Na_3FeF_6Nevertheless,these reactions,according to the author's experiments;proceedalmost quantitatively in meda.containing at least 50% by volume of alcohol.This paper reports the xperimental results obtained in the fundamentalstudies on the various factors influencing the accuracy of the volumetry,namely,the sensitivity and the necessary amount of sodium salicylate used asindicator,the pH value,the alcoholic concentration of the titration medium,the concentration of the fluoride taken for the determination and the timewhen alcohol should be added in the course of titration.Furthermore,a rapidvolumetric process with high accuracy is proposed together with its applicationsin ordinary analyses of sodium fluoride and other fluorine compounds.The proposed method is characteristic in using sodium salicylate asindicator,which shows sharp violet color with minute amount of ferric ion inmedium of pH 3 controlled with buffer solution,then titrating with standardferric nitrate,and adding proper amount of alcohol(the alcoholic concentra-tion at the end-point should be above 50%)during the titration,when themedium becomes orange yellow in color.The method may be summarized as follows:Take 5 ml of neutral sodiumfluoride solution of about 0.3 N in a small Erlenmeyer flask,add 2.5 mlof Walpole's buffer solution of pH 3(formed by dissolving 34.0 g ofcrystalline sodium acetate and 20 ml of 38% HCl in water,and making upto 250 ml)and 1 ml of 0.1 M sodium salicylate dissolved in 50% alcohol.After sufficient stirring,titrate with standard 0.3 N(0.05 M)ferric nitratesolution,using micro-burette until the medium becomes orange yellow,thisstep being reached after addition of about 4 ml of titrant.Then decolorizethe solution by adding 12.5 ml of absolute alcohol(or 13 ml of 95% alcohol),previously purified by redistillation with lime;stirring is necessary during theaddition.Further continue the titration until the light pink color formeddoes not fade after stirring for 30 seconds when observed over a white surface. In the analyses of sodium fluoride and other fluorine compounds con-taining interfering substances,such as divalent and polyvalent metallic ions,phosphate,silicate,borate,carbonate,sulfide ions and reductants acting on ferricion,it is necessary to separate fluorine from these interfering substances bythe distillation with sulfuric acid according to the method of Willard andWinter(20).Then the distillate is neutralized with dilute sodium hydroxideand adjusted to the proper pH with hydrochloric acid using p-nitrophenol asindicator.The solution is ready for titration as described.But in the caseof absence of these interfering substances except carbonate,for example,inthe determination of the concentration of sodium fluorde solution obtained bythe extraction of the crude product,produced industrially by fusing fluorsparwith sodium carbonate and silica,the above separation of fluorine by dis-tillation is dispensable.The anaIytical results obtained by the proposed method are in goodagreement with those obtained by the lead chlorofluoride process(8),whichis recognized as official method for the determination of fluorine in agriculturalproducts.

本文介绍一容量分析氟的新方法和在工业制品上的应用,并分析了一种工业制备的氟化钠液,所得的结果和氟氯化铅法所得的极为一致。对于影响该分析法准确度的各种因素:指示剂的灵敏度和滴定时适宜的用量、溶液的 pH 值、应加的乙醇量、操作中加乙醇的次序、以及氟离子的适宜浓度,均加以研究并找出适宜的情况。本法用硝酸铁为标准液,水杨酸钠作指示剂,在 pH=3左右作滴定;当溶液呈橙黄色时,加入适量的乙醇,使其浓度在终点时仍不低于50%。如有干扰物质如二价及多价金属离子、磷酸根、矽酸根、硼酸根、碳酸根、硫化物和还原物质可能与三价铁起作用者,均应分离之。
