reports on the bacteriology of the disease (p. 35). A summary of investigations 

 on the Isle of Wight bee disease (pp. 36-39), and a short account of Pasteur's 

 investigations on the Nosema disease of silliworms, known as pebrine (pp. 

 40-45), follow. A bibliography of 24 titles is appended. 



" Though it is highly probable that adult bees suffer at times from infectious 

 diseases other than microsporidiosis, there can be little doubt that the wide- 

 spread epidemic of recent years is mainly due to N. apis, and that preventiro 

 rather than curative measures will have to be adopted in order to limit its 

 ravages." 



The influence of temperature and moisture in fumigation, W. J. Schoene 

 {New York Sta. Tech. Bui. 30, pp. S-11). — The author reports upon a series 

 of fumigation tests with potassium cyanid that were carried on with caterpil- 

 lars of the brown-tail moth. 



"A greater number of caterpillars survived the fumigations made at low tem- 

 peratures than at higher temperatures; also fumigations made under humid 

 conditions were uniformly more destructive to the larvae than tests that were 

 conducted in a relatively dry air. It is suggested that the difference in the 

 results referred to above and the unusual resistance of the caterpillars to fumi- 

 gation are due largely to the conditions incidental to hibernation, viz, the 

 reduced moisture content and comparative inactivity of the insects." 



Studies on the flagellates of the genera Herpetomonas, Crithidia, and 

 Bhynchoidomonas, W. S. Patton (Sci. Mem. Med. and Sanit. Depts. India, n. 

 set:, 1912, No. 57, pp. 21, pi. 1, figs. 2). — Part 1 of this work deals with the 

 morphology and life history of Herpetomonas culicis. 



Color standards and color nomenclature, R. Ridgwat {Washington, D. C, 

 1912, pp. in +43, pis. 53). — This work, consisting of 53 plates and 1,115 named 

 colors, has been prepared with a view to the standardization of colors in their 

 application to biology. 



FOODS— HUMAN IflTTRITION. 



Influence of vegetables greened with, copper salts on the nutrition and 

 health of man, I. Remsen et al. {U. 8. Dept. Agr. Rpt. 97, pp. 461). — This 

 report of the Referee Board of Consulting Scientific Experts presents in detail 

 and discusses the experimental data obtained in the four series of investigations, 

 summarized below : 



Action of coppered vegetables on the health and nutrition of men, A. E. Taylor 

 (pp. 9-20S). — In these experiments normal young men were given mixed diets 

 containing measured quantities of canned vegetables (notably peas) colored by 

 copper, and the usual means were taken for measuring and analyzing the food 

 and excreta during a period of about 3 months. The author summarizes the 

 results as follows : 



" The sole results that are clinically apparent in the subjects who ingested 

 coppered vegetables in amount carrying up to 0.025 gm. of copper per day were 

 possibly slight disturbance of the alimentary tract in one; possibly a slight 

 increase in unresorbed nitrogen in a second ; and possibly a slight reduction in 

 the retention of nitrogen in the same individual. These data are of very 

 doubtful value. The important fact that has developed in these investigations 

 is the retention of copper. In all the subjects there was retention of copper, 

 varying from individual to individual ; in 1 subject very high considering the 

 dosage, in 2 marked, in others low. These data parallel those that have been 

 obtained by Professor Chittenden in animals. And, by analogy, we may infer 

 that the retention was in the liver. By further analogy with lead and mer- 

 cury, we may infer that a later redistribution may occur throughout the body.
