Meeting of the Society was held at the Royal Society of Arts on Thursday, March ist, 1923, Professor L. Bairstow, C.B.E., F.R.S., in the chair. The Chairman, in calling upon Major F. M. Green to read his paper on “ Air Travel, with Special Reference to the Helicopter,” said that many of those present would be able to> agree with the very critical review of the problem given by the lecturer, and it would be an advantage perhaps to the progress of aviation if the Society gave a technical opinion as to the value of the helicopter as a means of air travel.

In Nature of January 24, 1895, appears an abstract of a paper read before the Royal Society of Edinburgh on March 7, 1892, by Dr John Murray and Mr Robert Irvine, and published in the Transactions of the Society, vol. xxxvii. part 2, No. 23, entitled “Chemical Changes between Sea-water and Oceanic Deposits.”This is an account of a chemical examination of the sea-water salts in the water adhering to or retained in mud, with special reference to the formation of the deposit known as “Blue Mud.”Dittmar's analysis of sea-water is quoted and compared with an analysis of mud-water. The chief points of difference between the two is the occurrence in mud-water salts of 0·206 per cent. of ammonium sulphate, 0·729 per cent. of magnesium carbonate, and 0·18 per cent. of manganous carbonate; also that the total salts are low in proportion to the chlorine they contain.The occurrence of ammonium sulphate in this mud, and also of manganous carbonate, are facts of much interest; but there are some equations given to explain the chemical changes which the mud undergoes which are not strictly in accordance with facts. There are three points which I would desire to draw attention to: first, the reduction of the sulphates; second, the oxidation of sulphuretted hydrogen; and third, the formation of manganous carbonate.The equations are written without reference to the part played by water in the chemical changes involved, but it may have been thought that the accuracy sacrificed was compensated by the simpler form of the equations.

The characters previously used for the distinction of the species of Acrometopa are reviewed and modified differential diagnoses are given. Neotypes for A. macropoda (Burmeister) and A. servillea (Brullé) and a lectotype for A. syriaca Brunner von Wattenwyl are designated. From the Aegean island of Ikaría A. cretensis daedali nov. subsp. is described, and a key to the species and subspecies is given. The geographical variation within A. macropoda is described and discussed. A critical review of previous records in literature, together with the addition of new distributional data from Greece, has brought more logic in the known distributional pattern of the species.

In furtherance of the views put forward regarding the nutrition of the early embryo by the author in a preliminary note read before the Royal Society in February, 1905, the following series of experiments was carried out. The changes that take place between the growing embryo and the maternal secretion are in the mammalia, not easy to study, on account of the difficulties to be encountered, such as the minute size of the embryo, and the small amount of uterine secretion available. In birds, on the order hand, the uterine secretion, viz., the white of the egg, is abundant. The growing embryo can be examined easily at any stage which may be desired, and since all the changes which take place do so within the limits of the shell, the products of these changes are capable of accurate analysis.

Bhaishajya Kalpana is a specialized branch of Ayurveda scientifically explained by all the acharyas in their respective classical Samhitas. All the classical textbooks of Ayurveda give utmost importance to this particular branch. Acharya Sharangadhara gives wider explanation regarding the pharmaceutical preparations and procedures. The branch clearly explains the selection of drugs, the methods involved, the season to be considered, useful part to be collected, processing of the raw material, shodhana if any required, preparation of the medicine, steps involved, assessing the final product, siddha lakshanas obtained, the medicine to be discarded etc in detail along with the indications, Anupana to be used along with the medicine.

Ayurveda the science of life, not only deals with the prevention of diseases there by to maintain health but also with the alleviation of diseases. The unique position of man as a master mechanic of the animal kingdom is because of skilled movements of his hands and when this shoulder joints get obstructed, we call it as Apabahuka. While looking into comprehensive management of Apabahuka, Nasya, Uttarabhouktika Snehapaana Sweda, Raktamokshana etc. are commonly in practise, but Naasapana a special procedure explained in Vatavyadhi Chikitsa of Chakradatta with Dashamooli Bala Masha Kwatha is rarely in practise. This article enlightens about practise of Naasapana in the management of Apabahuka.

Data Requirements

Demand forecasting may be the most critical factor in the development of airports and airline networks. This chapter reviews various approaches used to forecast air travel and airport demand forecasting. It classifies existing methods according to the modeling approach used to evaluate the available data; then, the forecasting approaches are viewed in relation to data requirements. Finally, a new matrix classification scheme is introduced that combines both the data available and the technique used to evaluate this data in a more concise and manner.
