I have contrived several; that which is adopted in the present engine is perfectly secure and considering the very complicated nature of the conditions it is not very deficient in simplicity. This extreme complication of the conditions will perhaps be more felt by considering the following cases Time of Add. n 006012345678 101987655 22 007999990690 Time of Carr. 008000000700 Time of Adding Time of Carr. 0004365780064128976438052 0005634238990771023562 48 0009999918954899999990090 1 1 1 1 0010000019054900000000100 The complexity arises from the circumstance that the result of any carriage may effect the value of every figure on its left hand and that the effect of any carriage may terminate at any digit and a new carriage may commence its effect at the succeeding one; and this like its predecessor mayor may not be the precursor of many others.

It may be:Successive in its operation It may postpone its operations It may anticipate operations. Carriage may be successive in its operations: Those of the first class are the most simple but the time necessary for the performance is an effective impediment to their employment in Engines like that we are considering. Let us suppose unity to be added to 999999 then Add together 00999999 Time of 1st Carriage 00999990 Time of 2nd Carr. 00999900 Time of 3rd Carr. 00999000 1 00990000 Time of 4th Carr.

This process is necessarily slower in its operation than the former modes of rendering the calculated results permanent. It has however the advantage of possessing greater clearness; although the additional cost of taking off impression may in some instances be objectionable. Since however the invention of the number cards these modes of printing or engraving have ceased to become essential parts of a Calculating Engine. The absolute certainty of every printed result can now be obtained although the printing mechanism be totally detached from the calculating portion of the Engine, an improvement which it was impossible to make untill that point of the enquiry was attained.
