The animals do not die until some days have elapsed after they 

 have eaten the infected bread — in my experiments from 7 to 15 days 

 were required. It is claimed by the discoverers that dying animals 

 leave their burrows and runs and come into .the open where they die 

 or are easily caught, so that no offensive smells occur. On this point 

 I cannot speak, as my experiments, owing to the need of having relia- 

 ble " controls," were on rats in captivity. 



The price of the Liverpool virus is 15/s per dozen tubes plus 4/s 

 for the packing tin. A planter who wishes to try the virus would do 

 best to order a dozen tubes, or two may combine to order a dozen. 



It might be better if the orders were sent through me. If the 

 supplies could send a number of consignments together to one address 

 they could make special arrangements to store the package in a cold 

 room on the way out. This is important as it must be remembered jhe 

 virus is alive and not a dead inert thing like the ordinary rat poisons, 

 and therefore if it is protected against heat in tropical seas, a greater 

 number of tubes are more likely to retain their virulence.

TWO MANICOBA RUBBERS, 



Manihot dichotoma, Ule, 4 Jiquie Manicoba,' and Manihot piau- 

 hyensis, Ule, ' Romanso or Piauhy Manicoba.' 



Three lots of seeds of these two little known species of Manihot 

 have just reached the Botanic Gardens Singapore. One lot was kindly 

 sent by S. T. Dunn Esq., Superintendent, Forestry and Botanical 

 Department, Hongkong, and the other by W. N. Smith Esq., Superin- 

 tendent, Royal Botanic Gardens, Calcutta. 



These seeds are, I believe, a part of a consignment recently receiv- 

 ed from Brazil by the Director, Royal Botanic Gardens Kew. 



A large quantity of seeds from the same consignment has just been 

 received by us from Kew through the Crown Agents for the Colonies. 



Mr. Dunn writes that they have such poor results from this tree 

 in Hongkong (much too far north) that there is no desire to extend 

 their experiments and he sends the seeds here as the best way of 

 utilizing them. 



Mr. Smith sends a small packet of each species with the request 

 that we will in due course let him know what progress the plants make 

 in Singapore. 



The seed is slightly larger than that of Ceara but otherwise differs 

 very slightly in appearance. 



According to an article on these two Manicobas appearing in the 

 Kew Bulletin, 1908, page 59, it appears that the first intimation to 

 reach Kew of the existance of rubber yielding plants closely related to 

 the commonly cultivated Manihot Glaziovii took place in the early 

 part of 1906 when Mr. J. A. Davy, Manager of the Dumont Coffee 

 Company, Ribeirao Preto, Sao Paulo, Brazil, called at the Gardens and 

 left some seeds of the Jequie Manicoba. It further appears that on his 

 return to Brazil he sent more seeds with the following information; —
