The Annual Report of the Delegates for Forestry 

 at Oxford shows a large number of students in this 

 subject during 1921, no less than 52 (including 2 

 ladies) having been awarded the Diploma in Forestry. 

 Of these 45 obtained Government appointments. 

 Practical work was carried out by the students in 

 the Crown woods of Dean, Tintern, and High Meadow 

 and in Bagley wood near Oxford. TWe list of 

 published papers by members of the stafi shows 

 research mainly in insect and fungus pests. 



The annual report of Livingstone College for the 

 year 1920-21 has recently been issued. The College 

 is doing excellent work in training missionaries in the 

 elements of medicine, and 36 students entered for 

 var^'ing periods during the session. There is now an 

 accumulated deficit of 1021/. on the working of the 

 College, and subscriptions are earnestly asked for. 

 There is great need for bursaries of about 50/., which 

 could be offered to missionary societies or to suitable 

 candidates to enable students to enter for the full 

 course of the College. 



In the January number of The Fight against 

 Disease, published by the Research Defence Society, 

 an account is given of the Nottingham outbreak of 

 smallpox down to November 21 last. The number of 

 cases was 81, none of which proved fatal. Of these, 

 65 occurred in unvaccinated persons, and in none 

 of the others had vaccination been performed within 

 thirty-three years of the attack. All members of the 

 Hospital and Health Department staffs in contact 

 with the smallpox cases — some 120-130 in number- 

 were recently vaccinated, and no member of these 

 staffs contracted the disease. 



Messrs. Burroughs Wellcome and Co., of Snow 

 Hill Buildings, E.C.i, have just issued another 

 booklet, which may be had free on application. 



NO. 2734, VOL. 109] , 



" The Right Way in Photography " gives instructions 

 that reduce the process of taking photographs to a 

 mere matter of routine. The booklet will prove of 

 interest and use to those who do not need elementary 

 instruction by reason of the various tables it contains, 

 showing the times of development required at various 

 temperatures, using various tanks, and various 

 strengths of solutions ; and a very long Ust of plates, 

 classified according to the multiplier of the time 

 indicated that is necessary for each. 



The Journal des Dibats states that during a visit 

 to the National Porcelain Factory at Sevres the 

 President of the Republic and Mme. Millerand were 

 shown the operation of an experimental oil-fired 

 porcelain kiln. Hitherto the kilns have been fired 

 by wood (oak for the small and birch for the large 

 furnaces), but it is pointed out that the Copenhagen 

 factory has, for some time past, been using oil-fuel, 

 which affords better control and necessitates only 

 one man per kiln instead of two. The results of the 

 experiments at Sevres have been fully satisfactory^ 

 and although fuel oil is costly in France at present, 

 it is thought that its application to pottery and 

 porcelain firing may sooner or later revolutionise the 

 ceramic industry. 



The Spanish Nature {Iberica) continues to make 

 rapid strides, and the recent double number (January 

 21-28) is a remarkable production in every way. 

 many of the advertisements being excellently pro- 

 duced in colours. Among the contents may be 

 mentioned a full description, well illustrated, of the 

 new commercial university at Deusto, which is laid 

 out and equipped on modem lines. Another interesting 

 description is that of the largest quicksilver minefield 

 in the world at Almad^n. in the province of Ciudad 

 Real, which comprises to-day twelve separate mines 

 having an annual output of some 20.000 bottles of 

 mercury of 11-5 kilos each. There are notes on the 

 New Metropolitan Railway in Madrid ; an interesting 

 article, illustrated in colours, on geometrical anaglyphs 

 and stereoscopic vision ; a brief historical account of 

 developments in locomotive design ; some notes on 

 the progress of railway electrification in Italy ; and 

 the usual notes from foreign sources. 



We have received a circular announcing the pub- 

 lication in Italy of an Encyclopaedia of Science and 

 Arts. The work, which will be entirely new and 

 contain twice the number of articles of the present 

 edition of the " Encyclopaedia Britannica," is to be 

 under the direction of Prof. Giorgio Giuseppe Ravasini 

 da Buie d'Istria, and will be prepared in collabora- 

 tion with the foremost scientific authorities in Italy. 

 Articles and information from private individuals 

 will be welcomed and paid for, according to their 

 value and number, in money or in one or more sub- 

 scriptions to the complete work. The encyclopaedia 

 will be copiously illustrated by ordinary and coloured 

 plates, maps, plans, etc. The pubUcation of the 

 work is being undertaken by the publishing house 

 of the Accademia " Scienze ed Arte," and all inquiries 

 regarding subscriptions or contributions should be 

 addressed to Accademia " Scienze ed Arte," Sezione 

 Enciclopedia, Via Ugo Foscolo 2, Trieste (Italy).
