photographic printincr was to produce permanent 

 results, but, as many of those present knew, silver 

 prints were liable to change. Lately great interest 

 had been taken in the carbon method of printing. 

 It was not a new method, having been discovered 

 in 1S32. It was left to Blair, of Perth, in 18.59, 

 and Swan in 1SH4, however, to discover the 

 method of producing really good results by the 

 carbon process. By that process the silver was 

 replaced by any of the pigments used in water- 

 colour painting mixed with gelatine, and sensitized 

 with potassium bichromate. It was possible to 

 obtain by the carbon process any colour which was 

 required. Another advantage was that the films 

 were practically indestructible, and a third was 

 that it could be controlled so well by the person 

 developing. Mr. Kay then proceeded to 

 illustrate by means of practical demonstrations 

 the method of sensitizing the film, which, he 

 observed, had the disadvantage of only remaining 

 sensitive for a fortnight. He then developed 

 several photographs with the assistance of hot 

 water, the members being very interested in the 

 process. The printing was the same as in ordinary 

 ^photography. One disadvantage of the carbon 



process was that the image could not be seen in 

 the printing stage, but this could beov-^rcorae by 

 means of a new process called Ozotype, which had 

 recently been introduced. This is a simplified 

 civrbon process with which the Hon. .Secri?tary and 

 Mr. Kay had experimented, and obtained excellent 

 results. This process has been introduced since 

 the war has been on, therefore it is not strange 

 that the picture should print out a pure khaki 

 colour. The print is then washed and pressed 

 into contact with a piece of ordinary caibon 

 tissue, which is afterwards developed with hot 

 water in the usual way. It is worthy rf note that 

 there was a demonstration of this process before 

 the Koyal Photographic Society in London on the 

 same evening, so that our local Society is kept 

 well up to date. The various photographs were 

 handed round as they were developed, and were 

 examined with much interest by those present. 

 Kound the room were numerous carbon photo- 

 graphs and pictures, lent by the Autotype Company 

 and Elliott and Sons. 



The Chairman moved a hearty vote of thanks 

 to Mr. Kay for his most interesting and instruc- 

 tive lecture, which was unanimously accorded. 



THIRD AVIXTEE MEETING,

 Treasurer), and A. Lander (Hon. Secretary). 



Alter reading the minutes of the previous meet- 

 ing, some new members were elected, including 

 Dr. Brian Rigden and the Science Master of the 

 King's School. Mr. Small was elected an honorary 



member for his useful work in arranging the 

 Lepidoptera, etc., of the Museum. Attention was 

 then called to the exhibits, T;hich, besides the 

 numerous corals, included an interesting specimen 

 of Cohea Scandens, grown in the open air by the 

 Misses Holmes and Phillpotts. The plant was 

 shown with green flowers and others turned to 

 puiple, and also with the large capsule or fruit. 

 Several mineral specimen.s, which caused some 

 discussion, were brought from Mr. J. Overy, of 

 Hastings, by Mr. W. Cozens. On the table 

 were a number of garden flowers, tastetully ar- 

 ranged by Miss Holmes and Miss Phillpotts. 



The President stated that he had a very pleas- 

 ing announcement to make, which was that two 

 ladies, wlio had already done so much for the 

 oociety, were still anxious of doing more, and 

 desired to present to the Society some monthly 

 scientific pejiodical. He had agreed to see what 

 publication would be most needed, and meantimd 

 would leave the lu^mbers to guess who the ladies 

 were. The Chairman then briefly introduced Mr. 

 Morgan.
