Tokyo, June 4.
A "cold light" that gives off brilliant illumination with a minimum heat, invented by a young bachelor of science connected with the botanic cal laboratory of Tokyo Imperial University, Mr. Hiroshi Nakamura, is causing a sensation in scientific circles here.
The extraction of a luminous element from the firefly and noctiluca has been successfully experimented with by Mr. Nakamura, it was claimed, leading to.a belief that the discoveries may cause important changes in the manufacture of explosives.
Mr. Nakamura first experimented with luminous bacteria found in the firefly by adding vitamins and letting them propagate on the surface of a flask. An ash white light produced thereby. suddenly increased its brilliancy many times, giving off five candle-light power for one litre of flask. But when the bacteria died the light went out.
Not discouraged by this failure, the young scientist continued his experiments and later discovered that the light came from a luminous element which he was able to segregate.
By a special process he is able to extract the component parts of this luminous element. separately and has succeeded: in putting them together to produce a light equal to the light of the bacteria.
Thus it is claimed that the secret of a cold light "bacteria lamp" has been solved after puzzling scientists for many years, Plans will be made to utilize the invention when a "cold light" laboratory is established in the near future—Domei.
London, June 4, The question of the extradition of the alleged murderers of Mr. Cheng Shi-kang, Commissioner of Customs, from the British Concession in Tientsin to the local Japanese authorities is still the subject of exchanges between the) British Government and British diplomats in China, Reuter learns in London today.
It is quite untrue to say that decision has already been reached to hand over the wanted men, but it is anticipated that the British Consul-General in Tientsin, Mr. E. G. Jamieson, after contact with London, will resume discussions shotty with Japanese officials.
On the basis of reports that Mr. Jamieson had been instructed to comply with the recent Japanese request to surrender the assassins of Mr. Cheng Shi-kang the Chinese Ambassador here, Mr. Quo Tai-chi, ye terday visited the Foreign Office and lodged a strong protest.
The Ambassador pointed out that compliance with the Japanese roques was tantamount to de facto recogn tion of the "Provisional Government." "Mr. Cheng was assassinated in cinema in the Bı Concession on n s citizen, Mr.
s Glauser, chief engineer of the Energie Electrique de Tientsin, was also killed by a stray shot. Another foreigner, who attempted to prevent the escape of the assailant, was seriously wounded. Mr, Cheng was shot from behind, four shots entering his body.—Reuter, British Dug-out at
