notes to their proper places at the time they are made, it is well to have an 

 extra portfolio, which, in this case, would be marked, " Heart of Cat ; 

 Distribution." 



When its contents are to be distributed, the other portfolios are arranged 

 upon the table in some natural order ; the removal of their bands will 

 permit the upspringingof the side so as to expose the heading, and facilitate 

 the introduction of slips. 



110. Slip-box. This should be of stout tin, preferably Japanned. 

 The inside measures of length and width should be 22 cm. x 14 cm. (about 

 9 x 5.5 in.), which is nearly the size of the ordinary sheet of note paper. 



The depth is less simply stated. If the box has a folding lid, like the 

 " Japanned tray, postal size," here figured (Fig. 8), a depth of 8 cm. will be 

 needed. But the scientific student has such abundant need for shallow 

 trays, that he will usually find it more convenient to have, in place of the 

 folding lid, a single cover, 2 cm. deep. This should overlap the edge of 

 the box for 1 cm., resting on a welt. The depth of the box itself will then 

 be only 7 cm. 



If the slips are kept in envelopes instead of portfolios, the box and 

 cover together should have a depth of 9 cm. The Japanned tray, " standard 

 size," is only 5 cm. deep, and if the "postal size " is ordered, care should be 

 taken that it is of the actual width required for the postal card, since some 

 the of so-called " postal slips " are only 12.5 cm. long. 



The free edges of the box and cover should be turned, and the latter 

 should be "soldered." 



111. Cost of Materials. The tin box may be had for from 50 cents to $1.00. A 

 ;:n cash-box, with lock, costs $1.50. The Japanned tray, postal size, with slips, blocks 

 and guides, costs $2.65. 



" Roll Manilla," 40 inches wide, is 8 cts. per yard ; including the cutting, the slip- 

 folios cost at the rate of 10 cts. for 25-35. 



The bands are rated at $2.20 per M. for No. 372, and $5.85 for No. 385. By the hun- 

 dred they cost proportionally a little more. 



The slips may be cut by hand, but it is 

 usually cheaper to have the cutting done 

 by the stationer. They cost from 50 cts. 

 to $1.00perM. 



112. Other Methods. The slips 

 snay be placed in envelopes, sealed at the 

 code, and with the right end cut off. If 

 this plan is adopted, it is true economy to 

 use stout envelopes which will not readily 

 fray and tear. Cloth-lined envelopes of 

 the proper width, 9 cm. (three and one-half 

 inches! may be had for about $250 per J ED TEAT, rOB CATA-

Another way is to write the heading 

 upon a card the size of the slips, and put
