forwards, whereas in the common form the leaf is paler green, 

 the leaflets are flat, and the teeth straighter. The berries of the 

 green variety are globular with ten veins, resembling Currants, 

 the ordinary form being oblong and black. The taste is the 

 same in both.

Bouillie Bordelaise. — A communication was received by Mr. 

 Blandford from Mr. E. D. Till, The Priory, Eynsford, Kent, 

 stating that of twenty-six experiments, in gardens, fields, and 

 allotments, on different sorts of Potatos this season, they were 

 all completely successful. The mixture used consisted of 1 lb. of 

 copper sulphate, 1 lb. of freshly slaked lime, 1 lb. of syrup, and 

 5 gallons of water. The following are some of the more striking 

 results selected from Mr. Till's report : " ' Early Puritan,' once, 

 twice, and thrice syringed respectively, all were good ; the haulm 

 being green four weeks after the others had decayed. When not 

 syringed 25 per cent, were bad. ' Wilford Park,' considered a 

 good disease resister ; of seven rows not syringed 5 per cent, 

 only were bad. Of a row twice syringed all were good, cleaner, 

 and of a more regular size than the others. Of ' Sutton's 

 Abundance,' 20 to 25 per cent., ' Victory,' 20 per cent., and 

 ' Chancellor,' 3 per cent, were bad when not syringed. ' Reading 

 Giant,' when twice syringed, were all good, with more than a 

 fourth excess of crop ; all being cleaner and of a more regular 

 size than in the rest of the field, where it gave an average crop. 

 The haulm was green to September 25, six weeks after the others 

 had decayed. Of seven varieties grown on allotments, of 

 1 Snowdrop,' twice syringed, all were good ; once syringed, eight 

 tubers bad ; not syringed, sixteen bad. Of ' Early Puritan,' 

 twice syringed, twenty-five tubers bad ; about sixty being bad on 

 two adjacent rows not syringed. In a garden, ' Beauty of 

 Hebron,' once syringed, all were good and very clean ; while of 

 two rows not syringed 30 per cent, were bad." Mr. Till con- 

 cludes his report with the following general remarks : " The 

 leaves were very thoroughly syringed on both surfaces, and at a 

 date (July 1, 15, or 20 to 23) when growth had nearly attained
