A tentative table gives the minimum percentages of phosphorus deemed adequate for general farming in Wisconsin under different soil conditions.-F. M. Schertz. 5272. WAKSMAN, SELMAN A.

It may be used as a preservative, a vehicle of stains, and a general solvent in micro-technique. As a preservative it is best used as a concentrated (8 per cent) aqueous solution; it does not harden or shrink tissues but it does impart a slight yellowish-brown tinge. It dissolves coal tar dyes, alcohol, xylene, balsam, parlodion, and other reagents.-C. J. Lyon. Vol. 12 OCTOBER, 1923 No. 8 ENTRIES 5284-6131 BOTANICAL ABSTRACTS PUBLISHED MONTHLY UNDER THE DIRECTION OF THE BOARD OF CONTROL OF BOTANICAL ABSTRACTS, INC. CUMULATED INDEX, VOLUMES 1 TO 10, READY IN DECEMBER Cumulated subject and author indexes of Botanical Abstracts, volumes 1 to 10, are ready to print. The author index contains about 26,000 citations while the subject index has 60,000 entries with perhaps 3 or 4 times as many citations. All topics mentioned in the abstracts are suitably indexed. For a sample page, see cover page 4 of this issue. The completed work will comprise a volume of about 500 pages. The indexes will be offered for subscription within a few days. Subscribers will receive notice and an order blank in ample time to take advantage of a special reduced subscription price. Non-subscribers who desire a copy of the notice are requested to communicate at once with the Business Manager. Subscribers are reminded that the early volumes were sold on the basis of a book of 300-325 pages. It was planned, at the outset, to publish annual subject indexes; but when a variety of circumstances made this impossible the volumes were filled up with abstracts and author indexes. Upon examination it will be found that the first 10 volumes average 311.4 pages each. Price. It is estimated that the subscription price for the indexes will be $10. If a great many non-subscribers desire a copy it may be possible to reduce the price somewhat. The post-publication price will be much higher than the subscription price. Index for volume eleven. Subscribers to Botanical Abstracts are reminded that the index for volume 11 is in preparation and that its cost is included in the subscription price for that volume. Address.
