660 EXPERIMENT STATION RECOED. 



The best results, however, were obtained by using a long narrow 

 piece placed across the top of the section, or a rectangular starter 

 extending about halfway' down the section. 



The use of wooden or tin separators between the rows of sections is 

 strongly advocated by the author, since by their use the sections are 

 rendered much more regular. 



By determinations of the weight of diilerent samples of comb honey 

 it was found that the weight of the wax in thick combs is proportion- 

 ateh" less than in thin combs, the proportion varjdng from 1 : 19 to 1 : 28. 



The author tried a number of substitutes for pollen, the substances 

 being laid upon flat boards in the vicinity of the apiary. A small pile 

 of each kind of meal was put upon the different boards, and notes were 

 taken upon the apparent frequency with which the different kinds were 

 visited. The order of preference appeared to be as follows: Ground 

 whole kernels of oats, corn, wheat, fine wheat bran, cleaner dust, 

 cotton-seed meal, wheat bran, pea meal, wheat flour, rye flour, bean 

 meal, and barley meal. 



Bee poison and bee stings, J. Laxger {Sitzber Dent. Natui^w. 

 Med. Ver. Bohmefi, n. ser., 10 {1899), jjp. 291-310). Bee poison has 

 an acid reaction, but its toxic action is not due to formic acid. It is 

 free from bacteria and has the effect of slightly checking the growth of 

 micro-organisms. The author made observations on the sensitiveness 

 of different persons to bee poison. Of the individuals upon whom 

 observations were made, 11 were not sensitive to the poison, and 153 

 were sensitive when they first began the business of bee culture. 

 Brief notes are given on the various remedies which are popularly 

 employed for the treatment of bee stings. The author recommends 

 that in the case of persons who are oversensitive to the action of this 

 substance, chemical antidotes should be applied at the point of the 

 sting by means of a hypodermic syringe. 



On the metamorphosis of the young form of Filaria bancrofti in 

 the body of Culex ciliaris, the house mosquito of Australia, T. L. 

 Bancroft {flour. andProc. Roy. Soc. New South Wales., 33 {1899), jjp. 

 4^-62, Jigs. 8). — The author gives a brief critical account of the litera- 

 ture relating to this subject. It was found by experiments that the 

 FilarijE do not develop so rapidly in the body of mosquitoes as had 

 hitherto been suspected. According to the author's experiments, the 

 time required for this development is 17 or 18 days. The Filaria is 

 fir.st taken into the alimentar}' tract along with the blood sucked from 

 the host of the mosquito and later penetrates into the thorax. All 

 FilariBB which are for an}^ reason unable to make their waj'" to the 

 thorax of the mosquito ultimatel}^ die or, at least, fail to produce 

 young Filariaj. The juices of the alimentar\' tract seem to have an 

 injurious effect upon them and the}" are in some cases killed outright 

 and digested by these fluids. In dissecting mosquitoes infested with
