Shrinkage of cold-cured cheese during- ripening, S. M. Baucock, H. L. Rrs- 

 SELL, and U. 8. B.\er ( Wisconsin Sta. Bui. 101, i^p. 30, figa. 11). — This is essentially 

 the same as that i)ortion of the report of cooperative work previously noted (E. S. R., 

 15, p. 398) , which deals with the effect of cold curing U2:)on the loss in weight of cheese. 



The duration of the life of the tubercle bacillus in cheese, F. C. H.\rrisox 

 ( r. S. Ihpt. A(jr., Bureau of Animal Imlu.^try Rpt. 190S, j>p. 217-233). — This is a 

 translation of articles previously noted (K. S. R., 12, p. 985; 14, p. 292), with an 

 introductory statement by H. E. Alvord. 



Examination of Babcock test apparatus ( Connecticut Stute Stu. Rpt. 1902, pt. 4, 

 p. ./-■')■ — T'uring the year 600 pieci-s <if glassware were tested, of which 1 per cent 

 was found inaccurate. 



Statistics of oleomargarine, oleo oil, and filled cheese, 1900-1902, R. A.

Preparation of condensed milk by means of a centrifuge {Chem. Ztg., 27 

 {1903) , No. 78, }). 964) ■ — The milk in a thin layer is brought into contact with a cold 

 surface, revolved at the right speed to freeze the water out of the milk, and at the 

 same time to throw out the condensed product. The process is covered by German 

 patents.

Cytotoxic sera, Wanda Szczawixska {Arch. FarastL, 6 {1902), No. 3, pp. 321- 

 358). — The author presents a general discussion of cytotoxic sera, including the 

 method of preparation, their properties and actions, and the various practical uses to 

 which these sera have been put. It was found that specific toxic sera could be 

 obtained either from isolated cells or from groups of cells in the form of a tissue, and 

 that these sera owe their specific action to the presence of 2 substances, an inter- 

 mediary body and complement. As a rule these sera exercise a toxic effect when 

 given in large doses, a slightly injurious effect in medium doses, and a stimulating 

 action in small doses. 



Precipitating sera, H. Yallee {Jitv. Gen. Mkl. Yet., 1 {1903), No. 1, jyp. 9-18). — 

 If a given species of animal is repeatedly inoculated with albuminous matter of 

 another species, the serum of the inoculated animal soon acquires the power of pre- 

 cipitating in vitro-albuminous solutions coming from the second species. Notes are 

 given on the practical application of these facta in the examination of meat and milk 

 and in the study of animal diseases. 



The absorption of tetanus antitoxin in -wounds and the immunizing action 

 of dry antitetanus serum employed in the treatment of wounds aflPected with 

 tetanus, A. Calmette {Chmpt. Rend. Acad. Sri. Pfov'.s, 1J<J {1903), No. 19, pp. 1150- 

 1152). — During experiments carried out by the author it was found that guinea jjigs 

 could easily be immunized against tetanus by causing absorjition of small quantities 

 of antitetanus serum in wounds involving the whole thickness of the skin. Good 

 results, however, are usually not obtained from rubbing the wound with a brush 

 dipped in the liquid serum. Positive results, on the other hand, were almost always 

 obtained when a small quantity of finely-pulverized dry serum was sprinkled into 

 the wound. 



Experiments were also conducted for the purptjse of testing the action of dry anti- 

 tetanus serum wlien ])laced in the wound simultaneously with living tetanus bacilli. 

 In a test during which 10 guinea ])igs were inoculated and not treated and 10 others 

 inoculated and treated as just indicated, with dry antitetcnus serum, the latter 10 

 animals all failed to develop tetanus while the former 10 died after the usual course 

 of the disease.
