NOTES AND COMMENTS. 



Donation to the Library. — It will be remembered that 

 last year the Club's library was enriched by a valuable donation 

 from Madame Ville, of Paris, France, who presented to us, 

 through Mr. Shutt. twelve handsomely bound volumes contain- 

 ing the record of the labours of her husband, the late Professor 

 Georges Ville, the eminent agricultural chemist. During the 

 past month a further volume has been received from the same 

 donor. Its title is " Le dosage de r Ammoniaqm deFair etVabsorp- 

 tson de I' Azote de lair par les Plantes" and contains an account 

 of the chief work undertaken by this scientist. The thanks of 

 the Club have been forwarded to Madame Ville for her valuable 

 gift. 



Dr. Adolf Lehmann, a member of the Club, and a con- 

 tributor to the Ottawa Naturalist, who for years was 

 Assistant Chemist at the Experimental Farm, Ottawa, has been 

 appointed Agricultural Chemist for the district of Mysore, India. 

 This is an important position, and we offer him our heartiest 

 congratulations, wishing him all success in his new and distant 



field of labour. 



Since his return form Leipsic Dr. Lehmann has been at 



Queen's College, Kingston, as Demonstrator and Lecturer irl 



Organic Chemistry. Dr. Lehmann will leave in Canada many 



warm friends, and we trust that from time to time we may be 



able to inform them of the good work and good health of our 



erstwhile co-labourer.
