Incorporated in the text are 265 illustrations, and over three hundred experiments, which specially enhance the value of the book for schools and colleges where botany, agriculture, and horticulture are taught. _Nature._--"We have no hesitation in recommending it as _the_ elementary handbook for the agricultural student. The chapters on weeds and on diseases of farm-plants are distinctly better than those in any previous English works dealing with agricultural botany." _Journal of Education._--"A book which supplies what has for a long time been felt as a serious want in the literature of agricultural textbooks.... The book could hardly have been better." _MASSEE, GEORGE._ =A Text-Book of Plant Diseases=, caused by Cryptogamic Parasites. By GEORGE MASSEE, F.L.S., Mycologist and Principal Assistant, Royal Herbarium, Kew. With 92 Illustrations, drawn from Nature by the Author. Crown 8vo. 5_s._ net. _Literature._--"The book deserves to become the leading English textbook on the subject." _Farmers' Gazette._--"The manual which Messrs Duckworth have so attractively brought out for Mr Massee is one of the best of its kind that has yet appeared." _MOYLE ROGERS, THE REV. W._ =A Hand-book of British Rubi.= By the Rev. W. MOYLE ROGERS, F.L.S. Demy 8vo. 5_s._ net. DUCKWORTH & CO. 3 HENRIETTA STREET, COVENT GARDEN. Transcriber's Notes. The printer used raised dots for the decimal point; they were changed to periods. The dagger symbol was used in the keys; I changed them to the plus sign. There are many inconsistencies in the way words are abbreviated, the hyphenation, the Latin word endings and the capitalization of names, as well as the spelling in general; except where noted below, I left them as is. Changed "subq." to "subg." on page 11: "sp. subg. 6-7." Changed comma to period after "rufous" on page 23: "p. tinged rufous." Changed "peristently" to "persistently" on page 24: "persistently reddish flesh colour." Added missing period after "g" on page 30: "g. deep ochraceous." Sometimes the abbreviation "sp." is missing when the spores are described, such as page 31; I left them as is. Similarly, the abbreviation "P." is sometimes missing when the pileus is described as on page 50. I also left this as is. Added period after "var" on page 36: "var. violacea." Changed "striata" to "striate" on page 42: "striate at paler margin." Changed comma to period in entry for haematopoda on page 45: "Caespitose." Changed "mik" to "milk" on page 45: "giving out milk when broken." Changed period to comma after "lax" on page 49: "lax, campan. then exp." Changed "hariolarum" to "hariolorum" on page 51: "Differs from C. hariolorum." Although it appears that "P." should be after "Acrid.", I left it as is on page 56 in the entry for M. urens. Changed "palllid" to "pallid" on page 56: "pallid then rufescent."
