 of the original copy and in keeping with the 
 filming contract specifications. 
 
 Original copies in printed paper covers are filmed 
 beginning with the front cover end ending on 
 the last page with a printed or illustrated impres- 
 sion, or the back cover when appropriate. All 
 other original copies are filmed beginning on the 
 first page with a printed or illustrated impres- 
 sion, and ending on the last page with a printed 
 or illustrated impression.

 Les exemplaires origineux dont la couverture en 
 pepier est imprimie sont filmis en commencant 
 par le premier plat et en terminant soit par la 
 derniire page qui comporte une empreinte 
 d'impression ou d'i!lustration. soit par le second

 la derniire page qui comporte une telle 
 empreinte. 
 
 The last recorded frame on each microfiche 
 shall contain the symbol ^^{meening "CON-

 Maps, plates, charts, etc., may be filmed at 
 different reduction ratios. Those too large to be 
 entirely included in one exposure are filmed 
 beginning in the upper left hend corner, left to

 required. The following diagrams illustrate the 
 method:

 ARSENATE OF LEAD 
 
 Ottawa, March 27, 1914. 
 
 Wm illMSWOBTH, Esq., 
 
 Deputy Minister, Inland Revenue. 
 
 Sir, — I have the honour to submit herewith a report upon eighty-two sampl i 
 purchased as Arsenate of Lead in June, .July and August of last year. 
 
 Consequent upon many complaints regarding the character of this article as offereii 
 on the Canadian markets, a collection of 26 samples was made in 1910 (see Bulletin 
 No. 206). 
 
 Upon the work then done, and further study of the subject, the following standards 
 were recommended and are incorporated into tlie fourth schedule to the Adulteration 
 Act, l)y an amendment dated June 6 1913. 
 
 Arsenatk of Lead. — 1. An insecticide, containing at least 48 per cent of its weight of 
 of solids as a residue when dried to constant weight on the 
 steam bath ; and these solids must essentially consist of the 
 pentoxide of arsenic in combination with the monoxide of 
 lead. Water-soluble arsenic (expressed as the tri-oxide of 
 arsenic) must not be present to more than one per cent of the 
 weight of the in.secticide as sold. 
 2. Arsenate of lead shall lie regarded as adulterated if any 
 substance has lx?en mixed or packed with it so as to reduce, 
 lower or injuriously affect its quality or strength. 
 
 The results obtained by analysis of the S2 samples now reported must be judged in 
 accordance with the legal standards quoted. 
 
 The great majority of these samples are sold in the form of a paste, this being the 
 form in which the article is most readily available for use as a spray. In order that the 
 article may not dry out on the shelves of the dealer, it is usually put up in glass or tin con- 
 tainers, and hermetically sealed. Forty-one (41) samples of tliiscollection were furnished 
 to the analyst in the original container, and these are specified in the table. The 
 remainder were furnished in glass bottles or in tins which had been filled by our inspec- 
 tors from the larger packages of the dealer. Owing to the great difiiculty of sampling a 
 paste of this kind, some uncertainty attaches to the determination of the water content 
 
11 these cases ; and where the conUinern used by our tors have been imperfectly 
 
 ,:l,>-<i'<i, more or less loss of moisture occurs during si i.ige in the interval between 
 , nllectioii and analysis. Indeed many of the samples, as packe<l by the manufacturer, 
 sliowed clearly that loss of water had occurred through imperfect sealing. Home of 
 tli.'-i', put up'iu tin containers, showed the tin rusteti quite through, and the contents 
 iliv. This was particularly the case with strnple 54148. In spit« of these imperfections, 
 a MiHR-icnt number of samples, (more than 30) were received in such good condition as 
 t,, lustify the conclusion that, so far as content of solid matter is concerned, the manu- 
 ti.tiirprs of Arsenate of Lead endeavour t. meet the requirements of the legal definition. 
 
 Water soluble arsenic varies considerably, but in no case does it reach anything 
 likr tlie permitted limit. 
 
 With regard to the content of Arsenate of Lead in Arsenic Acid and Oxide of L*ad, 
 wliiih are the active ingredients of this insecticide, the following work reported by the 
 Niw Jersey Experiment Station (Bulletin No. 222) is important. " Arsenate of Lead 
 iv prepared by the action of I^ead Acetate or I^ad Nitrate on Di-Sodium Arsenate. 
 l'^'u\ii pure chemicals the product prepared from the Acetate contains theoretically 74-40 
 per cent of Oxide of I^ead and 25-60 per cent of Arsenic Anhydride. At a conference 
 i.t manufacturers and entomologists a standard agreed upon was that Lead Arsenate 
 shmild contain not over 50 percent water, and not less than 12-5 per cent. Arsenic 
 Ariiiydride. Fifteen samples of the commercial article gave the following results, calcul- 
 ated to a dry basis ; — 
 
 Arsenic Anhydride 1794 to 3330 per cer*. 
 
 Lead Oxide 62-48 to 70 63 " 
 
 The great difference noted between theoretical composition and the composition of 
 llir niiinufactured article is due to the formation of basic salts whose amount and 
 ili;irHeter vary with the method of manufacture, the mixtures of salts at diflFerent stages 
 uf the process determining (along with temperature and other conditions) the establishing 
 ■ f I'luilibria, which change with every change in the conditioning. It will be noted that 
 tlii- Canadian article, shows a greater uniformity and a nearer approximation to theore- 
 •■w:i\ requirements than the samples analvzed at the New Jersey Station. 
 
 The results now placed on record indicate that this article, as offered for sale in 
 C.inada, is of very satisfactory character. 
 
 I l)eg to recommend publication of this report as Bulletin No. 284. 
 
 1 have the honour to he. Sir, 
 
 Your obedient servant.
