and Chilian varieties were tested as well as Solatium Commersonii and 

 S. etuberosum. The Chilian varieties and some of the French and 

 German varieties proved immune, as did the two species mentioned. 

 None, however, appeared to be of much commercial value. 



In 191 5 Mr. Snell (77), who was appointed an inspector of the 

 Board in 1913, and was stationed at Preston, started, in conjunction 

 with the Lancashire Farmers' Association, a series of semi-official 

 trials in the grounds of Ormskirk Poor Law Institution, already men- 

 tioned as being the scene of the earlier trials conducted by the 

 Lancashire Education Committee. From this what are now known 

 as the Ormskkk Trials have arisen, and most of the well-known 

 varieties of potatos have been tested there. A full account of the 

 trials up to 1918 is given in the Supplement to the Journal of the 

 Board, issued March 1919 (78). 



The following varieties have been confirmed as immune since 1909 

 either by Mr. Snell (78), by Mr. Malthouse (46), in Germany by 

 Werth (87), or in America (47). Mr. Malthouse reported a few other 

 varieties immune, but some of these have either not been tried else- 

 where or have since proved to be susceptible, as the soil on which Mr. 

 Malthouse conducted his trials was not uniformly infected. As far 

 as possible synonyms have been deleted, especially in the ' Abundance ' 

 Group. There are some thirteen other German varieties which have 

 come through many tests immune, but have shown a few warts in 

 one or two trials, probably on rogues in the stocks.
