Investigations on flacherie, S. Sawamura {Bui. Vol. A<jr., Tohja, Imp. Tnir., 5 

 {lUOS), No. 4, pp- 403-44S). — An olahorati' series of bacteriological studies was carried 

 on by the author for the purpose of determining the connection of different bacterial 

 organisms \vitli flacherie of silkworms. A number of organisms were found in study- 

 ing this disease and detailed notes are given on their behavior on different nutrient 

 media. 



From the study of diseases of silkworms in connection with inoculation experi- 

 ments it A\as found that flacherie is claused by the growth of bacteria in the intestinal 

 juices of silkworms. Various kinds of micrococci were found in such location, 

 together with Bacillus megathermmi and coli bacillus. B. megatherium and one species 

 of micrococcus, Sarcina luiea, was found in the eggs of silkworms. About 10 species 

 of micrococci were found on mulberry leaves, and it apjiears from the author's inves- 

 tigations that flacherie is caused by eating mulberry leaves contaminated with these 

 1 )acterial organisms. 



Under onlinary circumstances, healthy silkworms resist the action of the bacteria. 

 When reared at high temperatures, liowever, or under imfavorabk' conditions the 

 worms may become infected. The author believes that flacherie is not caused by 

 any s})ecial form of bacteria. 



Eleanor Ormerod, R. Wallace {London: Jolm Murray, 1904, PP- XX-\-34S, pb. 

 SO, Jigs. 76) . — This volume is almost entirely occupied with an autobiography of 

 Eleanor Ormerod and selections from her entomological and other corresjiondence, 

 edited b}' Professor Wallace. The correspondence reprinted in this volume relates 

 to various problems connected with a great variety of injurious insects. 



Supplement to the entomologists' directory, H. Skinner {Philadelphia: Amer. 

 E)it. Sac, 1904, pp. :?S) . — Lists are given of entomologists whose addresses have been 

 changed and also of additional names and of certain entomologists whose names are

Eighth, report on food products, A. I^. AVinton et al. {C'onneclinU State Sta. 

 apt. 1903, pt. 2, pp. 107 -19S, figs. 26). — The work carried on during the year under 

 the ])rovisions of the State pure-food law is briefly spoken of in the introduction l)y 

 E. H. Jenkins. The station has collected for analysis 227 samples of food products, 

 30 sanijjles were submitted by private individuals, and 882 l)y the State Dairy Com- 

 missioner, making a total of 1,139. 



Chocolate and other products of the cocoa bean, A. L. Winion, E. M. Bailey, and M. 

 Sdvirman (pp. 123-145). — Of the 40 samples of chocolate examined 11 were found to 

 be adulterated, 7 were mixtures marked compound, and the remainder were not 

 found to be adulterated. Four of the samples were chocolate or cocoa containing 

 milk or casein. Analyses and other data are discussed at length. 



Coffee, A. L. Winton (pp. 145-148). — Seventeen samples of wOiole and 29 of ground 

 coffee were examined. In every case the wliole coffee was found to be pure. Nine 

 of the samples of ground coffee were found to be adulterated, chickory being present 

 in all such cases. In addition to chickory some of the samples containetl brown 

 imitation coffee made fnmi wheat Hour middlings or j)ellets made of i)ea hulls and 

 other ingredients. 



Lard, A. L. Winton and A. W. Ogden. (pp. 149-155). — Of the 134 samples examined 

 during the year 4 were sold as compound lard. Analyses showed that 48 per cent of 

 the remainder were actually mixtures containing large amounts of cotton-seed oil 

 "and consequently were grossly adulterated."
