into carbonic acid and water ; we find no tendency in these 

 oxides of carbon and hydrogen to become reduced to such 

 products as sugar, starch or cellulose, nay, much further, we 

 know no process by which such transformation might be 

 effected, still less are we acquainted with any internal forces 

 which can mould them into cells with functions to perform. 

 On this account a very great deal of thoroughly sound experi- 

 mental evidence is necessary to establish the doctrine of evolution 

 of life de novo. But so far as our present knowledge guides 

 us, whether we term it spontaneous generation, abiogenesis 

 or archebiosis, the process by which living things spring from 

 lifeless matter must be said to be only ideal."

Injecting Carbolic Acid into the Diseased Animal's Blood. 

 It occurred to Mr. Crookes, that as he could so successfully 

 attack and destroy the floating disease germs by atmospheric 

 disinfectants, he might so be able to neutralize the virus 

 in the blood by the introduction into it of appropriate 

 antiseptics, especially as Dr. De Ricci, Professor Polli, 

 Dr. McDowall, Dr. Waters and others had advantageously 

 used in this way sulphites and bisulphites as prophylactics 

 and cures in zymotic diseases. Injection of carbolic acid 

 (4 per cent, solution) was tried on an animal having cattle 

 plague; six ounces containing 105 grains of pure carbolic 

 acid were injected, the animal appearing to suffer no incon- 

 venience from it after the first trembling, consequent upon 

 the disturbing influence upon the circulation had subsided. 

 The cow gradually improved, and at length perfectly re- 

 covered. Seep. 301.

Dr. Calthrop published the following in the Lancet of 

 September 23, 1871 : 



Mr. F. had the eruption of small-pox developed on 

 March 6th ; the disease was of a mild kind, and he was 

 soon convalescent. Mrs. F., six months pregnant at the
