mixture made so striking a diflerence in 

 the plants that it could have been observed 

 by anyone passing along the side of the 

 field. The untreated rows had the foliage 

 smaller, more upright and badly spotted 

 with the fungus, while the sprayed plants 

 showed a rank growth of foliage, nearly 

 green throughout, more inclined to lop and 

 much less spotted than the untreated plants. 

 The difference between the roots in the 

 treated and untreated rows shown below 

 in pounds was not so great as that seen in 

 the foliage.

This is an increase of nearly twenty-six 

 per cent., or one-quarter in round numbers. 

 Therefore, the conclusion is that whatever 

 the crop may have been per acre in this 

 case, spraying with Bordeaux mixture 

 would have increased it one-fourth, or, for 

 example, from nine tons to twelve tons.

SCIENCE IN CANADA. 

 A NEW volume of the transactions of the 

 Royal Society of Canada (Volume XII.) 

 will shortly be issued. It will be the largest 

 of the series and will contain a bibliography 

 of the work of the Society, collectivelj' and 

 individually. This Society was founded in 

 1882 by the Marquis of Lome, at that time 

 Governor-General of Canada, and was or- 

 ganized, to some extent, on the basis of the 

 Institut de France. It consists of four sec- 

 tions, of which two are scientific, one being 

 devoted to the physical and chemical, the 

 other to the biological and geological sci- 

 ences. The system of HoyeK, introduced 

 originally by the French Section (I.), has of 

 late been adopted by the other sections also. 

 Carefully conducted, this feature cannot fail 

 to be of value to the future inquirer. An 

 accurate catalogue of deceased members' 

 works, with their dates of publication, etc., 



and an impartial estimate, ought to accom- 

 pany the biography. 



The scientific members of the Eoyal So- 

 ciety of Canada comprise several scientific 

 workers and writers of continental, a few of 

 European, fame. Except one year (1891 ) it 

 has always met at Ottawa, a rendezvous 

 which, though inconvenient for members 

 living at a great distance, has some import- 

 ant advantages, such as access to the Na- 

 tional Library, the Archives Bureau, the offi- 

 ces, museum and lil)rary of the Geological 

 Survej- and the Central Farm, with its la- 

 boratories, etc. All these departments are 

 represented in the membership. 



Not the least of the services that the 

 Eoyal Society has rendered to Canada is 

 that which arises from the afiiliation of the 

 principal local societies throughout the 

 Dominion. Some of these are iiuportant 

 bodies, which publish transactions of theu" 

 own, and have done a fair share of original 

 work. Among these may be mentioned 

 the Natural History Societj- of Montreal, 

 founded in 1827 ; the Canadian Institute 

 (1851), the Hamilton Association (1856), 

 the Nova Scotia Institute of Natural Science 

 (1862), the Entomological Society of On- 

 tario (1863), the Murchison Society, Belle- 

 ville (1873), the Ottawa Field iS^atural- 

 ists' Club (1879), the Canadian Society of 

 Civil Engineers (1888), the Natural His- 

 tory Society of British Columbia (1889) and 

 the Literary and Scientific Society of AVin- 

 nepeg (1879). It will be seen that this list 

 practically covers the Dominion from At- 

 lantic to Pacific, and when it is added that 

 every one of these bodies is represt^nted at 

 the May meeting by a delegate, who reads 

 a statement of the year's woi-k. published 

 in the ensuing volume, it will be ad- 

 mitted that the plan is not unfruitful. 

 Some of these allied societies have organized 

 their work into departments, and their re- 

 ports in the proceedings of the Royal So- 

 ciety form a valuable record of scientific
